Wilwood Residual Pressure Valve - New Style 4 PSI / Gold - Part #260-15365

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 #260-15365) is designed to optimize brake system performance by maintaining a minimum pressure in both disc and drum brake lines. This 4 PSI valve helps prevent excessive pedal travel caused by fluid drainage or caliper piston retraction, ensuring more consistent braking response. Crafted from durable billet aluminum and color-coded for easy identification, it is suitable for high-vibration applications such as off-road and dirt circle track racing. 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, enabling straightforward installation and reliable operation. Proper residual pressure management is critical in maintaining brake pedal feel and preventing brake drag, especially in complex or high-performance systems. This valve's design ensures fluid retention without impeding brake engagement, contributing to a safer and more responsive braking system. Whether used in disc or drum brake configurations, the Wilwood Residual Pressure Valve provides precise pressure control to enhance overall vehicle safety and handling. Its compact size and robust construction make it an excellent choice for race cars, off-road vehicles, and custom automotive projects seeking reliable brake line pressure regulation.
