Abstract

PURPOSE: To control the rear wheel braking hydraulic pressure when a car is running loaded with or without load, while compensating for the braking force of one rear wheel braking system damaged by the other system by means of a pressure reactive plunger respectively provided to the piston of both systems so as to vary the pressure receiving area thereof.
CONSTITUTION: The dydraulic pressures PM1 and PM2 are raised with strong application of the brake pedal while a car is running loaded, the left end of a plunger 19 is brought into contact with the inner end surface of a plug 17. Consequently the hydraulic pressure in a chamber 22 of a first piston 11 works to push the piston 11 to the right. Thus, whenever the car is loaded, a higher rise in pressure ensured for each rear wheel than when the car is unloaded. In addition, for example when the hydraulic pressure circuit in one rear wheel braking system RW2 is damaged, the hydraulic pressure against the force of a spring 16 is reduced to half. Accordingly, the hydraulic pressure PM1 chamber 24 is doubled as compared to the normal value as well as the hydraulic pressure PW1 for the rear wheel RW1 of the other system. With such an arrangement, the braking power thus halved can be compensated for by the normal circuit
