装置。[Scope of Claim for Utility Model Registration] A brake pedal that applies a pressing force, a booster that increases the pressing force applied by the brake pedal,
A master cylinder that discharges master cylinder hydraulic pressure further boosted by the pedal force increased by the booster, and the master cylinder hydraulic pressure discharged from the master cylinder is supplied to the front brake unit as front wheel cylinder hydraulic pressure. The front brake fluid pressure supply circuit and the master cylinder fluid pressure are supplied through a first rear brake fluid pressure supply circuit, and the plunger is moved relative to the valve body in accordance with the master cylinder fluid pressure, and the plunger is connected to the valve body. A hydraulic pressure control valve device that opens and closes interlocking valves to discharge adjusted rear wheel cylinder hydraulic pressure, and a second rear brake hydraulic pressure supply circuit that supplies the rear wheel cylinder hydraulic pressure to a rear brake unit. In the hydraulic brake device for a vehicle, the hydraulic control valve device further includes an actuator that changes the actuation force applied to the plunger according to a pressure signal from the booster or booster source. Hydraulic brake system for vehicles.
