Wilwood's four pound residual pressure valves retain a minimum brake line pressure to help eliminate excessive pedal travel. The four pound valve can be used in vehicles with high vibration brake systems like off-road or dirt circle track applications. The additional four pound residual pressure prevents fluid from flowing back without causing the brakes to drag. Four Pound Residual Pressure Valves are made from billet aluminum and color coded Gold for easy identification.
Wilwood's two, four and ten pound residual pressure valves retain a minimum brake line pressure to help eliminate excessive pedal travel in both disc and drum brake systems. The two pound valve is used in disc brake applications where the master cylinder is mounted below the horizontal plane of the calipers and fluid drain back occurs from gravity and vibration, thereby causing excessive caliper piston retraction and a longer brake pedal stroke. The minimal two pound residual pressure prevents fluid from flowing back without causing the brakes to drag. Four pound valves can be beneficial in high vibration brake systems such as off-road or dirt circle track racing. With drum brakes, a ten pound valve is used to compensate for return spring tension and maintain wheel cylinder sealing in the drums. Residual Pressure Valves are made from billet aluminum and color coded for easy identification. Valves are available with or without additional fittings. Valves with fittings are supplied with two 1/8-27 NPT to 3/8-24 inverted flare female fittings that will fit most domestic 3/16th hard brake lines.
