Method of controlling the inlet pressure of an anti-lock brake control valve

Method for controlling the inlet pressure (P26) of an ABS-control valve (13, 14) in a pressurized vehicle braking unit including at least one antiblocking system (ABS), where the ABS has at least one control unit (3), where a pressure control signal is sent to the ABS control valve (13,14) and the inlet pressure is adjustable to a smaller pressure value by brake pedal operation and the inlet pressure can be altered during braking.
