ABSTRACT:
A vehicle brake system having at least two brake pressure lines, via which a master brake cylinder communicates with wheel brake cylinders, at least one valve is incorporated in each brake pressure line to close the brake pressure lines in the event of anti-skid control. Each brake pressure line is also assigned a return pump, which bypasses the valve. At least one valve, in the currentless state or with the absence of pressure buildup in a brake pressure line, blocks this brake pressure line and communicates with a control unit for pulsed opening upon pressure buildup in the brake pressure line. Because of the additional disposition of a pressure valve and check valve in a bypass around the pulsed valve, expensive pressure reducers are dispensed with, with little additional expense in the anti-skid control system. Even if the anti-skid control system fails, stability during braking is assured.
