ABSTRACT:
A brake release mechanism for a spring-loaded, normally applied vehicle brake releasable by system hydraulic pressure when the system is disabled includes a pilot-operated brake release valve for isolating the brake from the disabled system, a brake control valve disposed between the system and the brake, and a manual hydraulic pump communicating with the brake for supplying fluid pressure thereto. A pilot-operated shunt valve is provided for shunting a hydraulic motor associated with the brake to allow free turning thereof during towing.
