Title: Trailer brake system

Abstract: A fluid pressure braking system for the trailer portion of a tractor-trailer combination vehicle includes valving mechanism which permits the vehicle spring applied, fluid pressure released parking brakes to be released after a single brake system failure. The system requires a pair of fluid pressure reservoirs, and includes the necessary interlock to permit both of the reservoirs to be charged while protecting the reservoirs in case of a leak in the system. The system also permits the vehicle parking brakes to be charged with the fluid pressure stored in either of the reservoirs. Both of the reservoirs normally provide the fluid pressure to actuate the vehicle service brakes.
