ABSTRACT:
Back pressure from the hydraulic power brake assembly of a vehicle acts on brake actuators to hold off spring apply brake assemblies through a vehicle operator actuated control valve. When the parking brakes are to be actuated, the operator turns the control valve so that it vents the hydraulic hold-off chambers to the hydraulic power brake sump, permitting the springs to apply the parking brakes. The hydraulic service brake system includes pistons in the brake actuators for normally actuating the brakes under pressure generated by the hydraulic power brake assembly. The pistons are mechanically acted upon by the spring apply forces when the parking brakes are actuated. The parking brake mode therefore uses the same wheel brake elements as does the service brake mode.
