ABSTRACT:
A wheel lock prevention apparatus for use in a motor vehicle includes a main passage connected between a master cylinder and a brake unit for transmitting a brake fluid pressure, a first normally-open solenoid-operated valve disposed in the main passage, a reservoir mechanism for storing a brake fluid, a second normally-closed solenoid-operated valve having one end connected to the main passage between the brake unit and the first normally-open solenoid-operated valve and an opposite end to the reservoir mechanism, and a pump mechanism disposed between the reservoir mechanism and the brake unit for returning the brake fluid from the reservoir mechanism to the brake unit. The pump mechanism is actuated when there is no signal indicating wheel locking and there is a signal representative of a movement of a reservoir piston in the reservoir mechanism.
