Abstract

An electronically slip-controllable power braking system for a motor vehicle, in which a controllably drivable pressure generator supplies multiple brake circuits connected in parallel to one another with pressure medium under brake pressure. Each of the brake circuits are separable through existing first control valves from the pressure generator and include second control valves that are connected downstream from the first control valves to control the brake pressure in the wheel brakes, which are connected with the brake circuits. An electronic control unit in the brake circuits has three devices, the third device puts the first control valve of a brake circuit into a passage position if a leakage is established downstream from the second control valve in this brake circuit and if it is established that the pressure generated by the pressure generator has at least approximately reached or exceeded a pressure limit of the first control valve.
