These in-line pressure valves retain a minimum brake line pressure to help eliminate excessive pedal travel in disc brake systems. Residual pressure valves are made from billet aluminum with 1/8" npt female threads for the inlet/outlet and color coded for easy identification. Ideal for drag racing, circle track, street rod and many off road applications.
With drum brakes, a ten pound valve is used to compensate for return spring tension in the drums. Features 1/8” pipe thread inlet and outlet you must a brake line adaptor sold separately. Most residual valves are color coded blue for 2 psi and red for 10 psi. An RPV DOES NOT cause brake drag, or cause the rear brakes to lock-up first!
