A hydraulic brake system with slip control, including a braking pressure generator hydraulically connected to at least one wheel brake by way of a main pressure line, a return line connected to the wheel brake and to the suction side of an auxiliary-pressure pump, an auxiliary-pressure line hydraulically connected to the braking pressure generator, and inlet and outlet valves inserted into the main pressure line and the return line and either closing or keeping open the pressure fluid passage in the main pressure line and in the return line, wherein a restrictor is controllable in the main pressure line between the inlet valve and the wheel brake permitting an unhindered hydraulic fluid passage in the main pressure line to the wheel brake in a first operating position, while the restrictor limits the pressure fluid flow to the wheel brake in another operating position.
