ABSTRACT:
A brake system for automotive vehicles comprises a dual-circuit hydraulic braking pressure generator (3) which is substantially composed of a power brake booster (4) and a master cylinder (5). Each one front wheel (VR or VL) is connected to the two brake circuits (1, 2) directly, while a rear wheel (HL or HR) is connected thereto by way of braking pressure modulator (6, 7). Further, for the purpose of pressure reduction, there is provided a pressure fluid line containing a separating valve (18) from the rear-wheel brakes (14, 15) to a pressure supply reservior (11). The auxiliary energy supply system comprises a pressure fluid pump (8), the pressure side of which can be "shot-circuited" with the suction side by way of a value (19) for reducing the auxiliary energy transmitted onto the braking pressure generator and thus for decreasing the braking pressure at the front-wheel brakes (12, 13).
