Wilwood Residual Pressure Valve - New Style 4 PSI / Gold

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 sytems 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 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.

The Wilwood Residual Pressure Valve, part number wil260-15365, is a high-quality billet aluminum component designed to optimize brake system performance in both disc and drum applications. This 4 PSI residual pressure valve helps maintain consistent brake line pressure, reducing pedal travel and ensuring reliable brake engagement. It is particularly beneficial in high-vibration environments such as off-road or dirt circle track racing, where maintaining steady fluid pressure is essential for safety and performance. The valve is engineered to prevent fluid backflow without causing brake drag, contributing to smoother operation and longer component lifespan. Its durable construction and color-coded design allow for easy identification and installation. The valve includes two 1/8-27 NPT to 3/8-24 inverted flare female fittings, compatible with most domestic 3/16-inch hard brake lines, simplifying installation. Designed for specific applications, this residual pressure valve is suitable for use in systems where consistent brake pedal feel and reduced pedal travel are desired, whether in racing or everyday driving scenarios. Built to meet rigorous standards, the Wilwood Residual Pressure Valve offers reliable performance and durability for a variety of automotive brake systems. It is an essential component for those seeking to enhance brake system reliability and efficiency.
