In a vehicle anti-skid braking system having a return pump 18, and a throttle valve 30, located between the master brake cylinder 5 and a wheel brake 6, the throttle valve is movable from its normal flow-through position into a throttling position against the force of an opening spring 34 and the wheel brake pressure at control inlet 36, by way of the pump outlet pressure at control inlet 35 during an anti-skid operation. The throttle valve serves to limit the rate of brake pressure rise in the wheel brake during an anti-skid operation. Upon completion of a braking operation with anti-skid operation, the wheel brake pressure is used as a control pressure for opening the throttle valve which thereby assumes its normal flow-through position earlier and more rapidly. <IMAGE>
