    • A hydraulic pressure control device in a vehicle anti-skid braking system includes a wheel brake actuating cylinder for braking a vehicle wheel, a fluid pressure supply passage connected between a master cylinder and the wheel brake actuating cylinder and having a restriction, and a first directional control valve disposed in the fluid pressure supply passage and having at least pressure-increasing and pressure-decreasing modes, the first directional control valve being normally in the pressure-increasing mode to connect the master cylinder to the fluid pressure supply passage. A second directional control valve is connected between the master cylinder and the wheel brake actuating cylinder, the second directional control valve being normally open to provide a bypass passage across the first directional control valve to connect the master cylinder passage to the wheel brake actuating cylinder. A control unit is responsive to a decelerating condition of the vehicle wheel for actuating the first directional control valve into the pressure-decreasing mode and for actuating the second directional control valve to shut off the bypass passage.
