ABSTRACT:
In the anti-skid brake control method of the present invention, braking pressure is controlled in such manner that it is transferred to pressure holding after it has been decreased for a predetermined time t.sub.1 when it is transferred from pressure increase to pressure holding during anti-skid brake control. Thus, the braking pressure held at a constant level can be maintained to a pressure approximately equal to the desired preset holding pressure. Therefore, the tendency of wheels to be locked can be prevented. As the result, the controllability of the anti-skid brake control can be improved without changing hardware arrangement of the relay valve and the like.
