The anti-skid brake control device includes an actuator having control valves therein for controlling the application of pressure from a master cylinder to the wheel cylinders. The pump which supplies hydraulic pressure to the master cylinder also supplies hydraulic pressure to a hydraulically operated device such as a power steering through the actuator to provide actuator operating pressure to regulate the control valves within the actuator. First and second throttle valves which are operable inversely with respect to each other in response to hydraulic pressure from the master cylinder are located in the actuator to control the hydraulic pressure applied to a pressure responsive piston which in turn controls a pressure reducing piston in the hydraulic pressure circuit between the master cylinder and the wheel brake cylinders.
