Wilwood Residual Valve - 10 LB

Residual valves help retain minimum brake line pressure to help eliminate excessive pedal travel in both disc and drum brake systems. Note: residual valves are needed when master cylinder is mounted lower than the caliper or wheel cylinder. Blue 2lb used on disc brake applications. Red 10lb used on drum brake applications. These inline residual pressure valves from Wilwood retain a minimum brake line pressure to help eliminate excessive pedal travel. These 2 lb. valves are used in disc brake applications where the master cylinder is mounted below the horizontal plane of the calipers and fluid drainback occurs causing excessive brake drag. With drum brakes 10 lb. valves are used to compensate for return spring tension in the drums. They're made from billet aluminum and are color-coded for easy identification.
