The present invention is directed to an anti-skid control system which includes a return passage provided for communicating a wheel brake cylinder with an actuator. A pressure pump is disposed in the return passage, and a reservoir is disposed in the return passage at the inlet port's side of the pump. The reservoir stores the brake fluid in the wheel brake cylinder through the actuator to decrease the wheel cylinder pressure. The pump discharges the brake fluid stored in the reservoir into the return passage thereby to gradually increase the wheel cylinder pressure. The amount of brake fluid stored in the reservoir is estimated on the basis of the amount of brake fluid fed into the reservoir and the amount of brake fluid discharged therefrom. The amount of brake fluid fed into the reservoir is estimated on the basis of the wheel cylinder pressure provided when the pressure decreasing operation starts, and in response to the pressure decreasing time. The amount of brake fluid discharged from the reservoir is estimated on the basis of the wheel cylinder pressure set when the gradual pressure increasing operation starts, and in response to the gradual pressure increasing time.
