ABSTRACT:
A vehicle brake system includes a source of fluid pressure adapted to supply a braking force a brake actuator including a parking brake chamber, and a combination valve fluidly coupling the brake actuator to the source of pressure, the combination valve having an inlet fluidly coupled to the source of pressure and an outlet fluidly coupled to the brake actuator. The combination valve includes within a single housing (i) a solenoid responsive to electrical signals to move from one position in which the parking brake chamber is fluidly coupled to the source of pressure in order to pressurize the parking brake chamber and release the parking brake, and another position in which the parking brake chamber of the brake actuator is vented in order to exhaust pressure within the parking brake chamber so that the parking brake is applied, and (ii) at least one of a manifold, an inversion valve, a double check valve and an anti-compounding valve.
