    • A hydraulic brake system with anti-lock control comprises a main cylinder connected to a reservoir, wheel brakes connected to the main cylinder by way of brake lines, and a recirculating pump, a suction side of which is connected to the wheel brakes by way of a first suction line. By way of a second suction line, the pump is connected to a pressure source. To control the pressure medium supply from a precharging device or other pressure source to the suction side of the recirculating pump as a function of the pressure in the second suction line, a hydraulically actuated valve is used. The inlet of the valve is connected to the precharging device via the pressure source, the outlet of the valve is connected to the suction side of the recirculating pump. The output pressure of the valve acts in a valve closing direction such that the valve closes once a pressure on the suction side of the recirculating pump exceeds a certain value. Thus, pressure medium supply is controlled as a function of the pressure on the suction side of the recirculating pump rather than the pressure at the valve inlet, to thereby limit the pressure on the suction side and to consequently subject the pump to less wear.
