A brake system for automotive vehicles is equipped with devices for the electric control of the brake force distribution and/or for the control of slip. The front wheels are connected to a pedal-actuated braking-pressure generator (1). In contrast thereto, the rear wheels (HR, HL) are acted upon with braking pressure by virtue of a braking pressure generator unit (5) which is composed of a vacuum servo unit (6) and a master cylinder (7) and which is actuated by a multidirectional control valve (4), such as a three-way/three-position rotary spool valve. The switch position of the valve (4) is responsive to the electric output signals of an electronic combining circuit (17, 17') which is, by way of wheel sensors, furnished with information about the rotational behavior of the wheels and the output of which circuit is electrically connected to the drive (19) of the three-way/three-position rotary spool valve (4). The brake energy for the rear-wheel brakes and the auxiliary energy for boosting the brake pedal force are taken from a vacuum source (Vac). |
