ABSTRACT:
The proposed vehicle brake system includes a brake fluid pressure device embodied as a brake booster, front wheel brakes rear wheel brakes and an anti-skid apparatus having valves for maintaining, reducing and increasing brake pressure. One of the brake pressure maintenance valves is associated with the rear wheel brakes and is further developed into a valve combination, which additionally includes a brake pressure regulating valve. The valve combination includes only one valve seat and one valve element, which serves both for keeping braking pressure constant in the anti-skid situation and to limit the rear wheel braking pressures during braking. The valve element is controlled on one side by a control piston acted upon by brake pressure and on the other by an electromagnet.
