A slip-controlled brake system for automotive vehicles comprising two static brake circuits (17, 18) into which pressure fluid can be introduced in case of control, comprising a master cylinder assembly (12) and a hydraulic booster (11), a hydraulic auxiliary-pressure supply system (2) as well as wheel sensors (S1 to S4) and electronic circuits (38) for determining the wheel rotational behavior and for generating electric braking-pressure control signals. The signals serve to control pressure-fluid inlet valves (4, 5, 6) and outlet valves (7, 8, 9) inserted into the pressure fluid lines (14, 17, 18) for the purpose of slip control. Connected upstream of the hydraulic booster (11) is a vacuum booster (1), the force-output member (51) of which is in operative engagement with the control piston (53) of the booster piston (54) of the hydraulic booster (1). The control piston (53) is coupled by way of a lever assembly (41) with the valve piston (20) which controls the pressure in the booster chamber (21), and with the booster chamber (21) communicating with the wheel brakes (HL, HR) of the rear wheels through the brake line (14).
