Abstract
A brake system is disclosed including a tandem master cylinder with a vacuum brake power booster and wheel brakes connected to the tandem master cylinder by brake lines. Each brake line contains a braking pressure modulator of a brake slip control appartaus, and interposed between the braking pressure modulators and the wheel brakes are braking pressure regulators which serve to reduce the pressure in the wheel brakes in relation to the pressure in the brake lines. To avoid impairment of the control behavior in the event of anti-lock control, the wheel brakes inserted after the braking pressure regulators are connectible by lines and solenoid valves in the braking pressure modulators directly to a return line leading to a supply reservoir.
