ABSTRACT:
In an anti-skid braking apparatus for vehicles of the type having a fluid-pressure control valve arranged between a master cylinder and a wheel cylinder for controlling the brake fluid pressure within the wheel cylinder, when it is detected that the vehicle stops, the fluid-pressure control valve is controlled so as to assume a pressure-maintaining mode and a pressure-increasing mode alternately for a predetermined period of time as long as the brake pedal is continuously depressed. As a result, the pressure of the fluid increases stepwise preventing the occurrence of uncomfortable kickback at the brake pedal.
