ABSTRACT:
In a hydraulic brake circuit for a motor vehicle equipped with a wheel anti-lock device and with a wheel anti-slip device, a solenoid anti-slip valve (48) is located in a conduit (26) connecting the master cylinder (12) to the wheel brakes (10), upstream of a solenoid relief valve (34) controlled by the computer of the anti-lock device. When a risk of slipping of the wheels is detected, the solenoid anti-slip valve (48) is energized and a pump (40) associated with the anti-lock device is actuated. In the absence of any actuation of the brake pedal (14), the brakes (10) are thus actuated automatically by way of the pump (40) which sucks up the brake fluid contained in the tank (28) of the master cylinder (12) via the solenoid anti-slip valve (48).
