Wilwood 260-13706 Blue Newer-Style 2-psi Residual Pressure Valve

Wilwood 260-13706 Blue Newer-Style 2-psi Residual Pressure Valve

Wilwood's residual pressure valves from Accesspeed retain a minimum brake line pressure to help eliminate excessive pedal travel in both disc and drum brake systems. The 2 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 2 pound residual pressure prevents fluid from flowing back without causing the brakes to drag. 4 pound valves can be beneficial in high vibration brake systems such as off-road or dirt circle track racing. With drum brakes, a 10 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.
