The Cal-Custom 10LB Residual Line Pressure Valve is designed to maintain a consistent 10 psi pressure in drum brake systems, ensuring immediate brake response and reducing pedal travel. Its red anodized aluminum construction offers both durability and corrosion resistance, while the 1/8" NPT inlet and outlet ports facilitate straightforward installation.

Manufactured by Cal Custom, a brand known for precision-engineered automotive components, this valve is tailored for drum brake applications where the master cylinder is positioned below the wheel cylinders. It effectively prevents fluid drain-back, keeping brake shoes close to the drums for optimal performance.

This valve is compatible with 3/16" brake lines and includes 3/16" inverted flare x 1/8" NPT adapters, making it suitable for various custom setups. It's an essential component for maintaining consistent brake pressure and enhancing the overall braking experience in classic and custom vehicles.
