Abstract
An anti-lock regulating system for brakes associated with wheels, has a first brake circuit including the brake of at least one wheel; a braking pressure regulating device for altering the braking pressure when the wheels have a tendency to lock; a hydraulic braking pressure generator coupled to the first brake circuit through the braking pressure regulating device; a second brake circuit including the brake of at least one other wheel; and a hydraulic control valve connecting the second brake circuit with the hydraulic braking pressure generator. The hydraulic control valve has a normally open position and a closed position. There is further provided a control piston having opposite first and second faces. The first face of the control piston is exposed to a pressure P.sub.R ' which is dependent from the braking pressure P.sub.R prevailing in the second brake circuit. Further, a control chamber bounded by the second face of the control piston is connected to the braking pressure regulating device through a throttle. The second face of the control piston is exposed to a pressure P.sub.St ' which is dependent, through the throttle, from the pressure P.sub.St as set by the braking pr…
