Claims

[Scope of utility model registration request]

a fluid pressure source, a booster that is actuated by fluid from the fluid pressure source in response to the depression force of the brake pedal and transmits amplified output to the master cylinder, and actuated by the brake fluid pressure generated by the master cylinder. a control valve provided between the fluid pressure source and the booster to adjust the pressure or flow rate of the fluid supplied to the booster; and the master cylinder. A pressure that is provided between the rear wheel brake and reduces the brake fluid pressure supplied to the rear wheel brake when the pressure exceeds a predetermined pressure value in response to at least the pressure within the rear wheel brake. The control valve controls the operation of the adjustment valve so as to change the pressure or flow rate of fluid supplied to the booster in response to changes in vehicle weight, thereby changing the output of the booster. and a second means for controlling the operation of the pressure control valve so as to change the pressure value at which brake fluid pressure starts to decrease in response to a change in vehicle weight. A brake device characterized by:
