In an antiskid brake system for a vehicle, a wheel speed sensor detects the wheel speed of a wheel of the vehicle, a valve unit controls the braking pressure applied to the wheel and an electronic control unit effects an antiskid control in which it causes the valve unit to periodically increase and reduce the braking pressure applied to the wheel on the basis of the wheel speed of the wheel. The electronic control unit compares the wheel speed detected by the wheel speed sensor with a reference value, determines that the antiskid control has terminated when the former is lower than the latter, detects the condition of the road surface the vehicle is running and makes lower the reference value as the condition of the road surface is more apt to cause the wheel to skid.
