Abstract
A brake system with anti-lock control and traction slip control is disclosed. The system includes a braking pressure generator composed of a master cylinder and a brake power booster. Also provided is an auxiliary-pressure supply system which generates an auxiliary pressure proportional to the pedal force for anti-lock control and generates an uncontrolled predetermined auxiliary pressure for traction slip control. The wheel brakes of the front wheels are connected to the master cylinder. By way of valve assemblies, the auxiliary-pressure supply system is connected to the wheel brakes of the front wheels in the control phases. The rear-wheel brake circuit is designed as a dynamic circuit and is fed directly by the auxiliary-pressure supply system.
