A hydraulic brake system with slip control for automotive vehicles, comprises a master cylinder (2) pressurizable by a hydraulic power booster (1), in which system valve members (39, 40, 43, 44, 47) are inserted between the master cylinder (2) and the wheel brakes (45, 46, 41, 42) connected thereto which serve to remove pressure fluid from the wheel brakes (41, 42, 45, 46). Pressure fluid taken from the wheel brakes (41, 42, 45, 46) is replenished out of the pressure chamber (6) of the hydraulic power booster (1). A stroke limitation of the brake pedal (7) is effected during slip control. To shorten the braking pressure generator (1, 2) while utilizing the known pre-charging effect, a stepped piston is employed as master cylinder piston (4), wherein a piston step (15) with larger diameter confines a working chamber (16) of the master cylinder (2) and wherein an annular surface (18) between the piston steps (14, 15) confines an annular housing chamber (19) which latter is connectable to the working chamber (16) by way of a supply valve (31) governed by the pressure in the working chamber (16). |
