In the preferred embodiment of the present invention, wherein said slave cylinder (111) is positioned at an inclined angle with respect to the said actuating link (210).
In an embodiment of the present invention, the vehicle is a two wheel drive vehicle. The brake assembly (105a, 105b) is installed in the live axle for the associated wheels. When the pedal (102a, 102b) is pressed by the user, i.e. if either a first pedal (102a) or second pedal (102b) is pressed fluid from the reservoir (104) is sucked into the respective cylinder i.e. first cylinder (103a) or second cylinder (103b) respectively, wherein the sucked fluid is pressurized in said cylinder and transferred to the respective brake assembly i.e. first brake assembly (105a) or second brake assembly (105b) respectively. The pressurized fluid enters the slave cylinder through the inlet. The pressurized fluid reciprocates the piston according to pressure of the fluid. The push rod in tandem to the piston actuates the brake by providing necessary thrust to the actuating link. The actuating link pulls atleast a disc of the plurality of discs (109) to stop the rotation of the axle. If the plurality of discs is worn out, the sleeve spring adjuster adjusts the push rod appropriately to maintain same pedal travel for the actuation of the brake.
Furthermore, if both the pedals (102a, 102b) are pressed together, the fluid from the cylinders traverses to the brake assemblies to actuate the respective brakes.
