TECHNICAL FIELD [0001] The present subject matter, in general, relates to a brake assembly for motor vehicle, and in particular relates to a fluid dispensing member for the brake assembly for the motor vehicles.
BACKGROUND [0002] Motor vehicles are one of the important modes of transportation. In the last few decades, two-wheeler automobile industry has shown a remarkable growth and development, gaining popularity as personal transport, in terms of technology as well as sales. Due to consistent advancement in technology, motor vehicles, such as motorcycles, scooters, light-weight scooters, trikes etc. that have a saddle-ride type profile, have succeeded in maintaining their popularity among different sections of society. Different sections of society, based on their requirement, utilize the aforementioned motor vehicles for various purposes, such as a recreational activity, a means of transportation, and for sports activities. As a result, it becomes pertinent for the two-wheeler automobile industry to constantly develop and modify the components of the two-wheeled vehicles to suit requirements of different riders.
[0003] Generally, considering two-wheeled vehicles, they are provided with a pair of brakes disposed on the front and the rear wheels. Typically, mechanically operated drum brakes are used in the vehicle. With the advent of braking technology, hydraulically or mechanically operated drum brakes and disc brakes have gained popularity with time. In some applications, disc brake is installed on front wheel(s) and in some other application, the disc brake is installed on both front and rear wheels. Typically, determination of whether to use disc brakes is ' primarily based on the capacity of the vehicle and the maximum load of the vehicle. Generally, for lesser capacity vehicles that are not expected to reach very high speed levels, a single disc brake is provided, preferably, on to the front wheel of the vehicle.
[0004] In accordance with the aforementioned ideology, various types of brake assembly have been developed for facilitating braking functionalities in the two-wheeled vehicles. Conventionally, braking systems that allow simultaneous actuation of a front brake and a rear brake upon application of a single brake lever

have gained widespread popularity across the globe. Such, simultaneous actuation of the front wheel brake and the rear wheel brake is performed by a brake assembly.

DETAILED DESCRIPTION [00017] Conventionally, motor vehicles are provided with a brake assembly for mainly slowing down or stopping the motion of the vehicle. The brake assembly, usually, includes at least one brake" assembly, such as a front wheel brake assembly and a rear wheel brake assembly for a front wheel and a rear wheel, respectively. Further, each of the front wheel brake assembly and the rear wheel brake assembly is connected to respective brake levers for actuation. The brake lever can be connected to the brake assembly in a variety of ways. For example, the brake lever can be connected to the brake assembly by means of a control cable. In such a case, one end of the control cable may be secured to the brake assembly, and the other end of the cable may be secured to the brake lever. This is typically used in drum brake systems. In another case, the brake lever can be connected to the brake assembly through a hydraulic means. This is generally applicable for disc brake systems. However, a combination of the cable and hydraulic hose can also be used. Further, the link or rod can be used for connecting the brake lever to the brake assembly. Consequently, actuation of the brake lever may result in actuation of the brake assembly and subsequently, the brake may be applied.
[00018] Generally, the front wheel and the rear wheel are provided with separate brake assembly. Conventional two-wheeler and three-wheeler brake assembly usually includes either completely hand-operated brakes for both the wheels or include a combination of hand-operated and foot-operated brakes. In the latter case; generally, the front wheel brake(s) are hand-operated, and include a front brake lever mounted on a handle of the two-wheeled vehicle for actuation, whereas the rear wheel brake(s) can be foot-operated, or sometimes hand operated according to the type of the vehicle.

[00019] Usually, during operation of the brakes, riders apply the rear wheel brake alone. Such a practice stems from the fact that actuating both the brake ,evers at the same time may be tnconvenient for the rider. In addition, when the front wheel brake is applied, sudden weight transfer towards the front wheel causes the front wheel to brake rapidly, and may result in a sudden jerk to the vehicle The sudden jerk may affect the ride quality and may disturb the balance and stability of the vehicle leading to an accident. However, on the other hand, the braking force applied to rear wheel brake has to be limited to prevent skiddmg of the vehicle. As a result, the deceleration of the vehicle may also be lirm.ed and subsequently, the stopping distance of the vehicle may be significantly long. [00020] Conventionally, in order to address the above-mentioned concerns, brake assemblies that allow simultaneous actuation of a front wheel brake and a •rear wheel brake by application of a singie brake lever have been developed. Accordingly upon actuation of the single brake lever, such a brake assembly may allow distribution of braking force to the rear.wheel as well as the front wheel of the vehicle. In addition to being convenient for the rider, such brake assembly may ensure that the deceleration of the vehicle be increased and subsequently, the stopping dtstance may be reduced without any skidding of the wheel. Further, as would be understood, in two-wheeled vehicles with such brake assembly, a front brake lever may also be provided to independently operate the front wheel brake. [00021] Further, in such brake assembly with front wheel brake assembly betng a disc brake type, a hydraulic fluid dtspensing member is mounted in the vicimty of the front brake lever for actuating a hydraulically operated discbrake by the front brake lever. This enables the front brake lever to actuate the hydraubc flmd dispensing member for dispenstng .requisite amount of hydraulic fluid to apply front wheel brake. Also, another fluid dispensing member is mounted ,n the v.cinity of the rear brake lever to actuate the front wheel brake when the rear wheel brake is actuated. Accommodation of two fluid dispensing members populates the handlebar assembly, particularly in two-wheeled vehicle, whtch «-typically having multiple system hke the head lamp assembly, switch assembly, brake and electrical cable etc. that are mounted and/or routed thereof. Such a brake assembly is not preferred.

[00022] Moreover, there exists another type of brake assembly, in which a single fluid dispensing member is used with either multiple pistons or with a . single piston for actuation by different levers that are pressing with one another to operate the piston. This single fluid dispensing member is disposed on one side of the handlebar assembly and it may include an assembly for mounting to the-handlebar and the assembly also supports levers that actuate the fluid dispensing member. Such type of brake assembly includes a lever acting as an intermediate lever, similar to a third order lever. In such systems, there is a need for providing higher braking force through the lever that could provide a lever ratio close to t to overcome poor braking performance, inadequate braking response, and hard-lever feel. This can be achieved by increasing the lever ratio.
[00023] However, the aforementioned (ever is subjected to certain limitations as the effort and the load lines, which are input and output lines, of the lever are made offset from each other along the lever pivot axis to avoid any interference of input cable with fluid dispending body. This results in an additional strain on the lever leading to breakage due to unbalance force couple acting thereon because of the offset. Therefore, tilting of the le.ver also occurs about an axis perpendicular to the pivot axis that would result in bending of the lever that would affect the functioning of the lever varying the brake performance and feel. Also, such tilting wears out specific portions of the pivot support member, like fastener or pin, and of the lever due to uneven contact that would result in part failure due to face rubbing or digging of the lever into the pivot support. Moreover, this offers diagonal support of the lever pivot which is uneven. Uneven load (pressure) intensity is at the pivot support. Moreover, uneven wear and tear of the lever pivot joints (surfaces), aggravate the lateral tilting of the lever over duty cycles. Moreover, excess hysteresis loss occurs degrading both transmission efficiency and free movement for return of the lever, leading to lever getting stuck from returning back when the brake is released or affecting lever function. With time, this leads to breaking' of lever that would impede the braking function/performance as the lever is typically connected to the rear brake lever, which the most actuated brake lever as discussed above. Also, it may lead to difficulties to recover wheel from skidding when brake lever is released.

[00024] Additionally, such assembly disposed towards one end of the handlebar provides poor aesthetics as the handlebar gets populated with the lever, the switch assembly and other ancillary components like cables. Consequently, the switch assembly is to be moved away from the reach of users hand in order accommodate such assembly in the vicinity of the brake lever. Otherwise, the switch assembly is to be moved towards handle grip / throttle grip where there is no space/gap. [00025] Moreover," from the aforementioned reasons, lever pivot with improved performance could not be achieved due to interference or fouling of the lever • pivot with handlebar tube which supports fluid dispending member. Also, the assembly has to be made bulkier to support and withstand the lever and the forces acting thereon which again would affect the packaging of the braking assembly & handlebar assembly.
[00026] Thus, there is a need for brake assembly that addresses the aforementioned and other problems in the prior art. The brake assembly as explained will provide a fluid dispensing member optimally disposed that enables improved packing and at the same time provides reliable braking operation. Also, the present subject matter will be capable of providing improved braking performance and braking feel with the same effort'from the user. [00027] Hence, the present subject matter provides a brake assembly for a motor vehicle. The brake assembly includes a synchronous brake lever, a single control, capable of actuating at least two brakes on different wheels. A fluid dispending member is mounted to a handlebar of the motor vehicle. [00028] It is a feature that the fluid dispensing member includes an actuation member that is actuatable by"an independent brake lever directly operated by user or by a secondary lever functionally connected to the synchronous brake lever by both the independent brake lever and the secondary lever. It is another feature that the present subject matter enables actuation of the actuation member" by independent brake lever or by the secondary lever or by the both, but independent of each other. It is an advantage that the brake assembly, in spite of providing a compact layout, retains the independent functioning of the levers without any interdependency like abutment.

[00029] It is an aspect that the fluid dispensing member is mounted to the handlebar and is disposed ahead of the handlebar away from the user. Further, the independent brake lever and the secondary lever are also disposed ahead of the handlebar. It is a feature, that the fluid dispensing member and the components working in conjunction with the fluid dispensing member are substantially disposed towards one side of the handlebar when viewed form top. It is an advantage that a switch assembly that the user operates can be disposed towards the user side or in an upward direction as ample space is available on the other side of the handlebar.
[00030] It is a feature that the fluid dispensing member supports the two levers including the independent brake lever and the secondary lever such that a first pivot point of the independent brake lever is disposed on one side of a piston axis of the actuation member. Similarly, the secondary lever is supported such that it is having a pivot point that is a second pivot point, disposed on other side of the piston axis. It is an advantage that the both the pivot axes are disposed away from each other without any interference between the rotation of the levers and also avoiding interference of the cable with the brake hose. The fluid dispensing member is secured to the handlebar through a holder member. The fluid dispensing member and the holder member are secured to the handle bar as an assembly, wherein the holder member and the fluid dispensing member conform and complement the profile of the handle bar for secure mounting. [00031] It is a feature that the fluid dispensing member is capable of accommodating the secondary lever with a wider width, which is along a pivot support length, without interfering with ancillary components like the handle bar. In one implementation, the secondary lever is having a width, which is along the pivot support length (axial), substantially greater than the width of the independent brake lever.
[00032] In one implementation, the secondary lever is functionally connected to a secondary cable. The secondary cable creates a pulling effect on the secondary lever by means of actuation of the synchronous brake lever. Moreover, another feature being, the independent brake lever rotates in a first direction of rotation during application of the independent brake lever. Likewise, actuation of the

synchronous brake lever result in rotation of the secondary lever in a second direction of rotation. Preferably, the second direction of rotation is opposite to the first direction of rotation. The direction of rotation is either clock-wise direction or counter-clockwise direction.
[00033] In one embodiment, the fluid dispensing member is having a first face disposed towards one lateral side of the vehicle. The independent brake lever and the secondary lever are securely disposed towards the first face. Further, the fluid dispensing member includes a first lever-support that is capable of rotatably supporting the independent brake lever, wherein in one implementation the first lever-support is substantially disposed on a face facing away from the handlebar tube. Similarly, a second lever-support is provided oh the fluid dispensing member for rotatably supporting the secondary lever, wherein in one implementation the second lever-support is substantially disposed on a face facing laterally outward. Further, the fluid dispensing member includes an abutment member that is capable of supporting the secondary brake cable extending, substantially along the handle bar, from synchronous brake lever towards the secondary lever; In an implementation, the abutment member is disposed on a face facing laterally inward. Thus, in such implementation, the elements of the fluid dispensing member are distribulively disposed thereon eliminating any stress or load at a certain region.
[00034] It is a feature that the abutment member and the second lever-support provided on the fluid dispensing member provide precise orientation with minimum variations between the secondary brake cable and the secondary lever. Moreover, the abutment member is disposed substantially away from the second lever-support, whereby substantial gap is formed therebetween to support the secondary brake cable from such distance. It is a feature that the fluid dispensing member enables the secondary cable to be in a desired orientation and is also supporting the secondary brake cable from overhang.
[00035] The fluid dispensing member includes a second face disposed towards the handle bar that abuts the handle bar. It is a feature that the fluid dispensing member is provided with components distributively disposed avoiding higher load concentration at a single portion.

[00036] In a preferred implementation, the first lever-support is provided at a first edge portion formed between the first face and a fourth face, which is facing away from the handle bar. The second iever-support is disposed at a second edge portion formed between the first face and the second face. Further, the abutment member is disposed at a third edge portion formed between the second face and a third face, which is at an opposite end of the first face. The fluid outlet port of the fluid dispensing member is disposed at a fourth edge portion formed between the third face and the fourth face. Thus, the fluid dispensing member accommodates the parts working with it in a compact and distributive manner. Further advantage being, the aforementioned parts can all substantially accommodated ahead of the handle bar.
[00037] It is an aspect that the fluid dispensing member supports the secondary lever that is having a first width, taken axially, substantially greater than the width of the independent brake lever with ease. It is a feature that the second lever-support of the fluid dispensing member is extending in a downward direction enabling the secondary lever, which is accommodated thereat, to have a desired width. It is an advantage that the second lever-support protruding, in downward direction is aesthetic look of the assembly, especially from the top, which is the viewing direction of the user.
[00038] It is a feature that the second lever-support is disposed in proximity to the mounting portion of the fluid dispensing member. Thus, this provides a larger structural area formed by the mounting portion and the fluid dispensing member to share and support the weight and operating loads of the wider secondary lever. [00039] The secondary lever includes a secondary arm for actuating the fluid dispending member and a cable connecting portion that are supported by a body portion. It is a feature that a plane passing about the cable connecting portion, which is an input line for provision of effort, and another plane passing about the secondary arm, which is the output line indicating the load, cut through the body portion. In other words, the secondary arm and the cable connecting portion are rigidly supported by the body portion due to the wider profile of the secondary lever. It is yet another advantage that the secondary lever provides adequate length to diameter ratio thereof due to the wider profile of the secondary lever.

[00040] Further, the cable connecting portion, which is a force input portion, is
disposed at a first distance from the pivot point of the secondary lever and the
secondary arm, which is force output portion, is disposed at a second distance
from the pivot point. The present subject matter provides a lever ratio around 1 as
the fluid dispensing member provides the flexibility to- accommodate the
secondary lever with desired width.
[00041] It is a feature of the present subject matter that the fluid dispensing
member provides the flexibility of selecting a higher lever ratio or a lower lever
ratio according to the requirement and to deploy on respective motor vehicles.
[00042] It is yet another feature that the secondary lever that is substantially
wider is capable of withstanding any unbalanced couple acting on the secondary
lever. Also, offset of the levers can be maintained to avoid any interference
between the brake cables and the fluid dispensing member. Therefore, the
secondary lever stays rigid and does not tilt.
[00043] In one embodiment, the secondary lever is a third order lever. In the
third order lever the force is between the fulcrum and the load. However, the
order of the lever mentioned herein is not limiting and may include a first order or
a second order.
[00044] It is an advantage of the present subject matter that levers are disposed
in proximity to the fluid dispensing member and the levers can operate
independent of each other thereby providing quicker system response
[00045] Moreover, it is a feature that the present brake assembly provides
improved reliability as the failure of the levers is reduced because of digging or
rubbing into face of the pivot is reduced due to the construction of the second
brake lever with elongated body that provides improved contact at pivot and at the
same time functional performance is improved. Thus, the frequency of
maintenance is reduced.
[00046] It is a feature that the brake assembly especially which is disposed in
the proximity to the handle bar end can be securely enclosed, by a head lamp
cowling of the vehicle.
[00047] The present subject matter is not limited to two-wheeled vehicle. As the
present subject matter in essence is applicable to a motor vehicle with one or more

front wheels arid one or more rear wheels. Therefore, the motor vehicles include a scooter type vehicle, a motorcycle type vehicle, a trike, or an auto-rickshaw. [00048] These and other advantages of the present subject matter would be described in greater detail in conjunction with the figures in the following description,
[00049] Fig. 1 (a) depicts an exemplary two-wheeled vehicle 100 with selective parts, in accordance with an embodiment of the present subject matter. The vehicle 100 includes a frame assembly 105 supporting a front wheel 110 and a rear wheel 115. The front wheel 110 and the rear wheel 115 are rotatably supported by front suspension system 145 and the rear suspension system (not shown). In one embodiment, the rear wheel 115 is additionally supported by a swingarm (not shown). The front wheel 110 is provided with a front wheel brake 120 and the rear wheel 115 is provided with a rear wheel brake 125 (shown in Fig. 1 (b)). The terms front wheel and the front wheel brake are not limiting and includes more than one front wheel or more than one front wheel brake" as and where applicable. Similarly, the terms rear wheel and the rear wheel brake are not limiting and includes more than one rear wheel or more than one rear wheel brake as and where applicable. In the present embodiment, the front wheel brake 120 is a hydraulically operated disc brake 120 that includes a disc that is concentrically • connected to the wheel and a caliper assembly that is functionally connected to the disc. The brake assembly 200 includes a synchronous brake lever 230 of a rear brake assembly 140 for actuating both the front wheel brake 120 and the rear wheel brake 125. An independent brake lever 205 of the brake assembly 200 is capable of actuating only the front wheel brake 120. In one implementation, the independent brake lever 205 and the synchronous brake lever 230 may be disposed on one end and other end of a handlebar H of the vehicle 100. In a preferred implementation, the independent brake lever 205 and the synchronous brake lever 230 are disposed on right-hand side and a left-hand side of the handlebar H, respectively. The handlebar H is functionally connected to the front. wheel 110 through the front suspensions 145 and is rotatably supported by the frame assembly 105 for steering the vehicle 100. In another implementation (not shown), the independent brake lever 205 may be used for applying the front wheel

brake 120 jointly with the rear wheel brake 125, while other brake lever is used to independently apply the rear wheel brake 125.
[00050] The vehicle 100 includes a power unit (not shown), that is either an internal combustion.engine, traction motor or both that is functionally connected to at least one wheel of the vehicle 100.
[00051] Fig. 1 (b) illustrates a schematic layout of the brake assembly of the two-wheeled vehicle 100, in accordance with the embodiment as depicted in Fig. 1 (a). The front wheel brake 120 is a hydraulically operated disc brake. Further, the independent brake lever 205 may be a hand operated lever actuated to apply the front wheel brake 120. In the present implementation, the synchronous brake lever 230 is also a hand operated lever mounted to the handlebar H. In another implementation, instead of providing the synchronous brake lever 230 on the handlebar H, a foot operated synchronous brake pedal (not shown) pivoted to the frame assembly can serve as the brake lever to jointly apply braking forces on the . front wheel brake 120 and the rear wheel brake 125.
[00052] Further, in the present embodiment, the rear brake assembly includes a distributor assembly 140 coupled with the rear brake lever 230. The distributor assembly 140 is connected to a hydraulic fluid dispensing member 215 of the brake assembly 200, disposed in proximity to the independent brake lever 205, through a secondary cable 225. Further, the brake lever 230 is connected to the rear wheel brake 155 through a rear brake cable 155. As can be seen in the present embodiment, the brake assembly 200 includes only a single fluid dispensing member 215 functionally coupled to one of the brake lever(s). The independent brake lever 205 is functionally connected to the front brake 120 through a front brake cable 150 to independently actuate the front wheel brake 120. The term 'brake cable' used herein includes a brake hose capable of transferring hydraulic force, or a cable movable within a sheathed cover for transferring mechanical force, as and where applicable.
[00053] Further, the secondary cable 225 is functionally coupled to an actuation member 217 (shown in Fig. 2 (a)) of the fluid dispensing member 215. For example, the fluid dispensing member 215 contains hydraulic brake fluid for actuation of one or more caliper(s) of the front wheel brake 120 and the actuation

member is piston. In an embodiment, the actuation of the independent brake lever . 205 and/or the secondary cable 225 causes a corresponding actuation of the hydraulic fluid dispensing member 215 that transmits braking forces to the front wheel brake 120 through the front brake cable 150 that is connected to the front wheel brake 120. In the depicted implementation, the front brake cable 150 is a hydraulic cable/hose, and the secondary cable 225 and the rear brake cable 155 are mechanical cables.
[00054] Fig. 2 (a) illustrates an enlarged top view of a portion the brake assembly 200, in accordance with the embodiment of Fig. 1 (b). Fig. 2 (b) depicts a top cross-sectional view of the brake assembly, the section of which is taken along the master cylinder piston axis and the first pivot axis PI of the independent brake lever 205, in accordance with the embodiment of Fig. 2 (a). In the present implementation, the brake assembly 200 is mounted to a column handlebar H. The handlebar H includes a tubular type single member, a split type, or any other known type of handlebar. The hydraulic fluid dispensing member 215, which is a master cylinder 215, includes a reservoir 216 and an actuation member 217 disposed therein. The terms master cylinder and fluid dispensing member are interchangeably used, hereinafter. The fluid dispensing member 215 is configured to store hydraulic brake fluid and the actuation member 217 is capable of moving along a piston axis P-P' to displace the brake fluid for engaging or disengaging the wheel brake.
[00055] The independent brake lever 205 is hinged/ pivoted to the fluid dispensing member 215 at a first pivot point PI and the independent brake lever 205 is capable of actuating the actuation member 217 during application of independent brake lever 205. Further, the secondary lever 210 is mounted to the ' fluid dispensing member 215 at a second pivot point P2. The fluid dispensing member 215 is secured to the handlebar H through a holder member 220. In other words, the holder member 220 securely mounts the fluid dispensing member 215 to the handlebar H by fastening.
[00056] The fluid dispensing member 215 is having a first face Fl towards one lateral side RH or LH. The independent brake lever 205 and the secondary lever 210 secured to the fluid dispensing member 215 are disposed towards the first

face Fl thereof. Further, the independent brake lever 205 and the secondary lever 210 are disposed on either sides of the piston axis P-P' along which the actuation member 217 is movable. In the present embodiment, the first pivot point PI of the independent brake lever 205 is disposed ahead' of the piston axis P-P' and the whereby the independent brake lever 205 with extended profile has sufficient space for movement towards the handle bar H tube. The second pivot point P2 of the secondary lever 210 is disposed rearward of the piston axis P-P', when viewed from top and has sufficient support for the secondary lever 210 that is relatively having shorter length.
[00057] The secondary cable 225 connecting the distribution assembly 140 to the secondary lever 210 is substantially extending along the handle bar H. The secondary cable 225 includes an inner cable 226 that is having one end connected to the secondary lever 210 and other end connected to the distribution assembly 140. Further, the secondary cable 225 includes an outer sheath 227 that supports the inner cable 226 slidably and the outer sheath 227 is secured between the distribution assembly 140 and the fluid dispensing member 215. In the present implementation, the outer sheath 227 is secured to the abutment portion 221 of the fluid dispensing member 215. Thus, the outer sheath 227 is a fixed member and the inner cable 226 is slidable therein.
[00058] During actuation of the independent brake lever 205 in a first direction of rotation Dl towards the handle grip disposed on one end portion in proximity to the fluid dispensing member 215, it rotates about the pivot point PI in a clockwise direction when viewed from the top. Similarly, by the actuation of the synchronous brake lever 230, the secondary cable 225 gets pulled, that results in rotation of the secondary lever 210, in a second direction of rotation D2, which is in an anti-clockwise direction, when viewed from top. The independent brake lever 205 includes a lever arm 206 that is capable of actuating the actuation member 217 during application of the independent brake lever 205. Correspondingly, the secondary lever 210 includes a secondary arm 211 that is -capable of actuating the actuation member 217 during actuation of the synchronous brake lever 230 creates pulling of the secondary cable 225 causing pivotal motion of the secondary lever 210 thereby resulting in actuation of the

fluid dispensing member 215. The fluid dispensing member 215 securely supports the independent brake lever 205 and the secondary lever 210 being disposed on one side of handlebar tube H when viewed from top and away from the user. [00059] Fig. 2 (c) depicts an exploded view of the brake assembly, as depicted in Fig. 2 (a) in accordance with the embodiment of the present subject matter. Fig. 2 (d) depicts an isometric view of the fluid dispensing member, in accordance with the embodiment of Fig. 2 (a). Fig. 2 (e) depicts the top view of the fluid dispensing member. Fig. 2 (f) depicts another isometric view of the fluid dispensing member. The fluid dispensing member 215 includes a first lever-support 218 that is capable of pivotally supporting the independent brake lever 205. The first levers support 218 includes.a first member 218-1, and a second member 218-2 that are spaced apart to accommodate a pivot portion of the independent brake lever 205. The first lever-support 218 includes apertures that define the first pivot point PI. In preferred implementations, the first lever-support 218 is extending at a front facing side, ahead of the piston axis P-P\ of the fluid dispensing member 215. Further, the fluid dispensing member 215 includes a second lever-support 219 formed by a third member 219-1, and a fourth member 219-2 spaced apart to accommodate the secondary lever 210 thereat. Thus, the gap between the members 219-1 & 219-2 is substantially equal to the width Wl of the secondary lever 210. The width Wl is substantially greater than the width define by the first lever-support, wherein the width of the first lever-support is essentially the gap between the arms 218-1, 218-2 of the fluid dispensing member 215. The second lever-support 219 includes apertures enabling the secondary lever 210 to pivot about the pivot point P2. A pin 223 rotatably supports the secondary lever 210 that is either riveted or secured using a circlip. The second lever-support 219 is disposed on other side of the piston axis P-P' extends in a lateral direction RH/LH without interfering with the handlebar tube H to which the fluid dispensing member 215 is mounted. The gap between the third member 219-1 and the fourth member 219-2 is substantially greater than the gap between the first member 218-1 and the second member 218-2, whereby the second lever-support 219 is capable of supporting a secondary lever 210 whereby the secondary lever 210 that is substantially wider is accommodated

thereat. In the present embodiment, the actuation member 217 is disposed on the . first face Fl of the fluid dispensing member 215 that is facing substantially one lateral side RH/LH. The orientation referred herein is with respect to the handlebar tube H in an orientation providing straight line movement of the vehicle.

The cylindrical pin 228 that is pivotable about the connecting portion 212 enables rotation of the secondary lever 210 due to the pulling effect of the secondary cable 225. The secondary cable 225 is capable of being within a desired orientation as the secondary lever 210 and the cylindrical pin 228 adjusts to the change in orientation of the secondary lever 210 by virtue of the cylindrical cross-section. The secondary lever 210 includes an abutment portion 214, which is an elastic member-mounting portion, provided at a substantial mid-portion of the secondary lever 210 for connecting an elastic member (not shown) that provides the return force. Further, the abutment portion 214 is reinforced by a support wall 236 structurally supporting the abutment portion 214.
[00069] Further, the body portion B of the secondary lever 210 accommodates a metal insert (not shown) that is either encasted or press-fitted about the cylindrical hollow portion defined by the body portion B. The body portion B is having the width Wl, wherein a plane passing about the cable connecting portion 212, which is an input line for provision of effort, and another plane passing about the secondary arm 211, which is the output line indicating the load, cut through the body portion B. The width Wl of the secondary lever 210 provides adequate length to diameter ratio thereof. Further, the cable connecting portion 212, which is an input portion, is disposed at a first distance LI from the pivot point P2 and the secondary arm 211, which is output portion, is disposed at a second distance L2 from the pivot point P2. The present subject matter provides a lever ratio L1/L2 around 1 thereby providing flexibility of selecting a higher lever ratio or a lower lever ratio according to the requirement. Further, the fluid dispensing

member assembly 215 is capable of securely supporting the secondary lever 210 capable of providing a lever ratio greater than or equal to 1. [00070] Fig. 4 depicts a bottom perspective view of the brake assembly, in accordance with the embodiment of Fig. 2 (a). The fluid dispensing member 215 comprising an actuation member 217 for actuating the front wheel brake 120, and said actuation member 217 is capable of being actuated by the independent brake lever 205 and the secondary lever 210. Each of the independent brake lever 205 and the secondary lever 210 are capable of actuating the actuation member 217 independent of each other. The independent brake lever 205 and the secondary brake lever 210 are rotatably supported by the fluid dispensing member 215. The independent brake lever 205 is having a first pivot axis, which is analogous to the first pivot point PI, is disposed on one side of the piston axis P-P' passing along direction of motion of the actuation member 217. Similarly, the secondary lever 210,is having a second pivot axis, which is analogous to the second pivot point P2, disposed on other side of the piston axis P-P'. The integrated fluid dispensing member 215 along with the independent brake lever 205 and the secondary lever 210 are disposed ahead of the handlebar tube H. The integrated fluid dispensing member 215 is secured to the handlebar tube H through the holder member 220. [00071] The second lever-support 219 of the fluid dispensing member 215 is disposed such that the second lever-support 219 is downward with respect to the handlebar tube H and not extending upward. Similarly, the secondary lever 210 having wider width Wl is disposed in proximity to the handlebar tube H, in the present embodiment. Further, the second lever-support 219, supporting the secondary lever 210, extends in downward direction with respect to diametric center of the handlebar tube H, whereby the brake assembly 200 is compact from top, which is the general viewing angle of the user. Major portion of the brake assembly 200 is disposed ahead of the handle bar H tube.
[00072] Further, both the independent brake lever 205 and the secondary brake lever 210 those are" capable of actuating the actuation member 217 of the fluid dispensing member 215, independent of each other, are disposed in proximity to the fluid dispensing member 215. This provides both the pivot points/axes PI, P2 at an adequate offset with the handlebar tube H to avoid any fouling or

interference thereof. Consequently, components like switch assembly mounted to the handlebar tube H are also disposed compactly without any interference. [00073] Further, the fluid dispensing member 215 is capable of accommodating the lever with a wider width without interfering with ancillary components. Further, unbalanced couple, if any, acting on the secondary lever 210 does not tilt the secondary lever 210 as the width Wl is substantially greater than the first distance LI and the second distance L2. Further, in one implementation, the secondary lever 210 is having the axial length/height, referred to as width Wl, being about 1.5 times of the first distance LI and the second distance L2 whereby the secondary lever offers an elongated body B that provides improved contact with pivot reducing the digging/rubbing. Further, the assembly disposed towards one lateral end portion of the handlebar H provides aesthetically pleasing assembly as the levers 205, 210 and the corresponding components are disposed away from the user ahead of the handlebar tube H.
