Resid. Press Valve 2lb

The Wilwood Residual Pressure Valve 2lb is a precision hydraulic component engineered for disc brake systems that demand consistent pedal feel and reliable stopping power across a range of driving conditions. Built for street performance vehicles, track cars, and custom brake builds, this compact residual pressure valve maintains a steady 2-pound baseline pressure in the brake lines when the pedal is released. This ensures your brake fluid remains primed and ready, eliminating the lag and sponginess that can develop in systems prone to air intrusion or vapor lock, especially in high-heat or high-performance applications.

Constructed from aluminum and finished in blue anodized coating for corrosion resistance, the residual pressure valve features 1/8 inch NPT inlet and outlet ports, making it compatible with standard hydraulic brake line fittings found on most aftermarket and OEM systems. The valve body measures 1.600 inches in overall length, allowing it to fit into tight engine bays or brake component clusters without requiring extensive plumbing modifications. The 2-pound residual pressure specification is ideal for disc brake systems without load-sensing proportioning valves; it keeps brake fluid under slight pressure during idle, preventing air bubbles from forming and maintaining a firm, responsive brake pedal from cold start to sustained track work or towing applications.

Technicians and builders installing custom or upgraded brake systems benefit from this valve's straightforward function and compact design—no adjustments or maintenance required once installed. It's essential for vehicles running braided stainless lines, larger rotors, or modified master cylinders where baseline pressure control is critical to pedal consistency. Whether you're upgrading a classic car's brakes, building a track-focused suspension setup, or troubleshooting a spongy pedal in a high-performance daily driver, the Wilwood 2lb residual pressure valve delivers the hydraulic stability your system needs for confident, repeatable braking performance.
