Speedway Motors 2 PSI Disc Brake Residual Pressure Valve Purple Inline Check Valve 1/8 NPT Ports for Master Cylinder to Caliper Applications

Ever had problems with a spongy pedal or slow, unresponsive brakes? If so, you may need a residual pressure valve installed in your brake line. A residual valve acts like a one-way or check valve to maintain brake system pressure to eliminate the problems of a spongy pedal. This 2 PSI residual valve is installed inline between the master cylinder and disc brake calipers to keep 2 PSI of residual pressure at the caliper after the brake pedal is released. This ensures that you will have a high, firm pedal next time you press the brake pedal. If your master cylinder is located below the floorboard, installing a 2 PSI residual valve is highly recommended. If your master cylinder is mounted on the firewall, a residual valve is generally not needed because gravity will provide a natural residual pressure within the brake line. Our residual pressure valve features a distinctive purple anodized finish with 1/8" NPT port at each end. Use 2 PSI residual valves for disc brake applications only. Inverted flare or AN threaded adapter fittings to the 1/8" NPT female thread will be required and are noted below and available as required.

• Pressure Control Function: Acts as a one-way check valve to maintain brake line pressure and help eliminate a spongy pedal feel
• 2 PSI Rating: Designed specifically for disc brake systems to maintain light residual pressure without causing brake drag
• Inline Installation: Mounts between the master cylinder and brake calipers to retain pressure after pedal release
• Mounting Applications: Recommended for low-mounted under-floor master cylinders and beneficial in select firewall-mounted systems
• Universal Connections: Features 1/8" NPT female ports on both ends; compatible with inverted flare or AN adapters for 3/16" brake line connections
