In a fluid pressure-operated anti-skid braking system for vehicles, operating fluid from a supply is supplied to the wheel brake through a fluid-flow control valve interposed between the supply and the brake. A deceleration responsive device responsive to a skid signal is incorporated for operating the control valve to relieve the brake pressure of the fluid supplied to the brake when the deceleration of the wheel is excessive and exceeds a pre-determined value. A memory for storing a memory pressure dependant on the brake pressure at a skid is incorporated, and the memory pressure operates the control valve directly during a first stage of brake re-application, and provides a changeover point between first and second stages of brake re-application. The second stage comprises continued re-application but at a reduced rate of pressure increase.
