Abstract
In a slip-controlled automotive vehicle brake system, to reduce the number of the valves used, while simplifying the system construction, the wheel brake cylinders are connected to relief chambers (123, 133, 124, 134) of compensating cylinders (120, 130), the connection between the master-brake-cylinder pressure chambers (80, 90) and the relief chambers (123, 124, 133, 134) being closable during slip control.
