ABSTRACT:
In a brake system with slip control comprising a pedal-actuated vacuum booster and a dual-circuit master cylinder, to which the wheel brakes are connected via brake lines, comprises an auxiliary-pressure source with a hydraulic pump and a pressure-compensating and pressure-fluid supply reservoir wheel sensors and electronic circuits for determining the wheel rotational behavior and for generating electric braking-pressure control signals which serve to control electromagnetically actuatable pressure-fluid inlet valves and outlet valves inserted into the brake lines and into the supply line for slip control, a valve is provided in order to control the auxiliary pressure and to adapt same to the pressure in the pressure chambers of the master cylinder. The wheel brakes of the rear wheels are jointly connected via the supply valve to the supply line which forms the third brake circuit and which is acted upon by controlled pressure, while the wheel brakes of the front wheels are connected to the two static brake circuits in which the non-return valves are inserted.
