Abstract
A system for use in a vehicle with a brake pedal and a brake circuit. The system includes a master cylinder assembly configured to pressurize fluid therein in response to movement of the brake pedal, a sensor assembly configured to generate a pedal position signal indicative of position of the brake pedal, an electronic control unit configured to (i) generate a brake request signal in response to generation of the pedal position signal, and (ii) generate a selector control signal, and a selector valve assembly being moved from a first mode to a second mode in response to generation of the selector control signal, the master cylinder assembly is (i) isolated from fluid communication with the brake circuit when the selector valve assembly is positioned in the first mode, and (ii) in fluid communication with the brake circuit when the selector valve assembly is positioned in the second mode.
