Abstract
Disclosed is a brake system wherein the wheel brake is hydraulically connected with a relief chamber of periodically variable volume. A valve 11 controlled by control electronics is switched to connect the chamber to either the wheel brake or a reservoir synchronously to the direction of movement of a piston in the relief chamber to either increase or decrease pressure at the brake for the purpose of antilock and slip control of the brake.
