A hydraulic brake system provided with a wheel slip control means (2) for use with automotive vehicles, comprising a master cylinder (2) pressurizable by a hydraulic force booster (1), wherein valve devices (32,33 and 34, 35, respectively) are provided between the master cylinder (2) and the wheel brakes (25, 26 and 30, 31, respectively) connected to the master cylinder. Pressure fluid is dischargeable through the valve devices from the wheel brakes 25, 26 and 30, 31, respectively) with pressure fluid discharged from the wheel brakes being replenishable by pressure fluid from the pressure chamber (10) of the hydraulic force booster (1) or an auxiliary pressure source (49). During the slip control, a stroke movement of the pedal brake (8) is effected in order to enable the hydraulic brake system to be employed both as a brake-slip-controlled system (ABS-system) and as a traction slip-controlled system (TSC-system). Pressure conduits (53, 54) are connected to the brake lines (51, 52) leading from the working chambers (16, 20) of the master cylinder (2) to the wheel brakes (25, 26, 30, 31) which, through the valve devices (37, 39 and 38, 40, respectively) can be connected to the pressure chamber (10) of the hydraulic booster and/or to the auxiliary pressure source (49). Locking valves (41, 42) are additionally provided in the brake conduits (51, 52) through which the connections of the brake conduits (51, 52) to the working chambers (16, 20) of the master cylinder (2) can be interpreted. |
