Patent ID: 8167381

Claim:
A brake fluid pressure control device for a bar handle vehicle comprising: a front wheel brake system which imparts a braking force to a front wheel; and a rear wheel brake system which imparts a braking force to a rear wheel, wherein at least one of the brake systems comprises: a master cylinder which generates brake fluid pressure in accordance with an operation amount of a brake operation element; first and second wheel cylinders both of which impart the brake force on one of the front and rear wheels; a first hydraulic path which communicates the master cylinder with the first wheel cylinders; a second hydraulic path which is branched from the first hydraulic path and connected to the second wheel cylinder; and a boosting unit which boosts the brake fluid pressure in the second wheel cylinder without boosting the brake fluid pressure in the first wheel cylinder, wherein the boosting unit comprises: a cut valve which is disposed in the second hydraulic path; a suction channel which communicates the master cylinder with the second wheel cylinder so as to detour the cut valve; and a pump provided in the suction channel, and the boosting unit operates the pump so as to supply the brake fluid to a passage between the second wheel cylinder and the cut valve while closing the cut valve, thereby boosting the brake fluid pressure in the second wheel cylinder without boosting the brake fluid pressure in the first wheel cylinder.
