ABSTRACT:
Disclosed is a brake fluid pressure control apparatus in which an anti-lock control mechanism is connected to a hydraulic booster. A large-diameter piston is combined with a small-diameter piston so that the pressurization effected by the master cylinder M/C can be augmented by virtue of the difference in diameter between these pistons before it is transmitted to the wheel cylinder W/C. By moving forwards, the pistons cause a fluid supply passage between the fluid pressure source and a wheel cylinder W/C to be opened. With this structure, the size and weight of a brake fluid pressure control apparatus can be reduced.
