WE CLAIM:
1. A bar handle vehicle brake device comprising:
two front wheel side and rear wheel side brake
operators;
two front wheel side and rear wheel side wheel brakes;
a hydraulic brake system configured to cause one of
the wheel brakes to generate a braking force by a brake
hydraulic pressure generated by an operation of one of the
brake operators or by a pump;
a mechanical brake system configured to directly
operate the other wheel brake to generate a braking force by
an operation of the other brake operator;
detecting means configured to detect the braking force
of the other wheel brake; and
a control device,
wherein the control device executes control for
operating the pump according to a detection result of the
detecting means.
2. A bar handle vehicle brake device comprising:
two front wheel side and rear wheel side brake
operators;
two front wheel side and rear wheel side wheel brakes;
a hydraulic brake system configured to cause one of
the wheel brakes to generate a braking force by a brakehydraulic pressure generated by an operation of one of the
brake operators or by a pump;
a mechanical brake system configured to directly
operate the other wheel brake to generate a braking force by
an operation of the other brake operator;
detecting means configured to detect an operating
amount of the other brake operator and
a control device,
wherein the control device executes control for
operating the pump according to a detection result of the
detecting means.

3. The bar handle vehicle brake device according to
Claim 1 or Claim 2, wherein
the hydraulic brake system includes:
an output hydraulic pressure line extending to a master
cylinder;
a wheel hydraulic pressure line extending to one of
the wheel brakes;
a pressure regulator provided between the output
hydraulic pressure line and the wheel hydraulic pressure
line;
the pump configured to suck a brake fluid of the output
hydraulic pressure line and discharge the brake fluid to the
wheel hydraulic pressure line; and a suction valve provided between the pump and the
output hydraulic pressure line.
4. The bar handle vehicle brake device according to
Claim 3, wherein the suction valve is opened by a pressure
difference between a brake hydraulic pressure on the master
cylinder side and a brake hydraulic pressure on a suction
port side of the pump, at which a vacuum is created when the
pump is operated.
5. The bar handle vehicle brake device according to
Claim 4, wherein the suction valve is integrally provided
with a reservoir configured to store a brake fluid released
from the wheel brake.
