ABSTRACT:
A hydraulic braking pressure control apparatus adapted to a vehicle braking system for a set of wheel brake cylinders, which includes an electric operated valve assembly provided to control hydraulic braking fluid under pressure supplied from a master cylinder to the wheel brake cylinders and an electrically operated fluid pump cooperable with the valve assembly to recirculate hydraulic fluid from each of the wheel brake cylinders into a fluid reservoir of the master cylinder when a set of road wheels of the vehicle tend to be locked in braking operation. The valve assembly is constructed to restrict recirculation of hydraulic fluid from either one of the wheel brake cylinders when the hydraulic pressure in the other wheel brake cylinder is decreased by operation of the fluid pump.
