Wilwood Residual Pressure Valve - New Style with Fittings - 2 lb / Blue

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 260-13783) is designed to optimize brake system performance by maintaining minimal line pressure, preventing excessive pedal travel in both disc and drum brake setups. Crafted from durable billet aluminum and color-coded for easy identification, this valve ensures reliable operation across various applications. The 2-pound residual pressure setting is ideal for disc brake systems where the master cylinder is positioned below the calipers, such as in certain classic or custom vehicles, helping to prevent caliper piston retraction caused by gravity and vibration. This results in a more consistent pedal feel and quicker brake response without brake drag.

The valve includes fittings: two 1/8-27 NPT to 3/8-24 inverted flare female fittings, compatible with most domestic 3/16-inch hard brake lines. Its compact design allows for easy installation in tight spaces, making it a versatile choice for custom builds, restorations, or performance upgrades. The 2 lb residual pressure setting is particularly effective in reducing pedal travel in disc brake applications, especially where fluid drain-back issues are common. Additionally, the valve's construction from billet aluminum ensures durability and longevity under demanding conditions.

Suitable for a range of automotive brake systems, the Wilwood residual pressure valve helps maintain consistent brake performance by preventing fluid backflow and ensuring proper seal and piston positioning. Whether upgrading a vintage vehicle or customizing a high-performance build, this valve offers reliable, precise pressure regulation that enhances overall braking efficiency and safety. Its straightforward installation and trusted Wilwood quality make it an essential component for professional mechanics and automotive enthusiasts alike.
