A vehicular hydraulic brake system with anti-locking, wherein there is provided a master cylinder (27) with a power booster (9) connected upstream thereof for the purpose of supplying the brake-actuating members (32, 33, 36 37) with pressure. Valves (34, 35, 38, 39) are provided for the pressure control of the brake-actuating members (32, 33, 36, 37) and wherein a pressure piston (23) of the hydraulic power booster (9) can be acted upon by the pressure of an auxiliary pressure source (1) in the brake's release direction. To structurally simplify the brake system, the present invention provides that a housing chamber (24) which can be acted upon by the pressure of an unpressurized supply reservoir (5) or of the auxiliary pressure source (1), alternatively, is confined by an end face of the pressure piston (23) remote from the pedal.
