PROBLEM TO BE SOLVED: To reduce generation of sticking in of a brake pedal by prohibiting operation of an oil pressure working on a wheel in a pressure increasing pattern from determination of a finish of antiskid control to a stop of a vehicle. SOLUTION: When an electric control unit 10 detects a locking condition of a front right wheel FR, for example, an antiskid control condition is accomplished and a control signal is fed so that an opened pressure increasing valve 21 is closed while a closed pressure reducing valve 31 is opened, and consequently a brake pressure in a wheel cylinder 7a is lowered. In this way, the locking condition of the front right wheel FR is released, and when restoration of the front right wheel FR rotation is detected by means of the electronic control unit 10, the transmitted control signal is stopped again, and the pressure reducing valve 31 is closed again. As a result, the brake pressure in the wheel cylinder 7a is maintained. Subsequently, if restoration of the front right wheel FR rotation is detected further, signal transmission is stopped again, and the pressure increasing valve 21 is closed again. In this way, a brake pressure in the wheel cylinder 7a is increased.
