An integrated vehicular braking system which can provide ABS/TC/VSC control using a common auxiliary high pressure source for two circuits includes a separate boost valve pilot operated to control the flow from the high pressure source to provide brake boost. The boost valve is also actuated by a single solenoid to provide the fluid pressures necessary for full ABS/TC/VSC control. The boost valve is removed from a master cylinder/booster assembly, thereby minimizing pressure drops across the dynamic seals, and is not mechanically coupled to the booster or brake pedal. The boost valve is pressure balanced, thereby requiring reduced forces to operate the valve while providing improved brake pedal feel.
