Abstract
The proposed vehicle brake system has a hydraulic brake booster, a master brake cylinder, wheel brakes and a pressure source for operating the brake booster. The vehicle brake system also has an anti-skid device, which comprises an auxiliary cylinder with an auxiliary piston and valve assemblies. In the anti-skid situation, the auxiliary piston is acted upon, controlled by one of the valve assemblies, and it acts counter to the brake booster and thereby lowers the pressure in the master brake cylinder. By stopping the valve assembly that is associated with a wheel threatening to skid, the brake pressure in the associated wheel brake drops. Valve assemblies are also further developed such that by including the valve assembly, drive slip at driven wheels can be limited by means of pressure from the pressure source.
