Claims

[Scope of utility model registration request]

a pneumatic source; a booster actuated by compressed air from the pneumatic source to transmit amplified output to a master cylinder; and front and rear brakes actuated by brake fluid pressure generated by the master cylinder. is provided between the pneumatic pressure source and the booster, and controls the air pressure supplied to the booster in response to electric signals corresponding to the brake pedal depression force and vehicle weight, respectively. an electro-pneumatic converter that controls the output of the device;
provided between the master cylinder and the rear brake, and responsive to at least the pressure within the rear brake;
A pressure control valve that reduces the brake fluid pressure supplied to the rear wheel brakes when the pressure exceeds a predetermined pressure value, and the pressure value that starts reducing the brake fluid pressure in response to a change in vehicle weight. A brake device comprising means for controlling the operation of the pressure control valve so as to change the pressure control valve.
