Residual Valve Kit

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 redesidual valve acts like a one-way or check valve to maintain brake system pressure to eliminate the problems of a spongy pedal. This 10 PSI and 2 PSI residual valve is installed inline between the master cylinder and drum brake wheel cylinders to keep 10 PSI of residual pressure at the wheel cylinder for drum brakes and 2 PSI at the wheel cylinder for disc brakes.This ensures that you will have a high, firm pedal next time you press the brake pedal.

Our residual pressure valve features a distinctive purple anodized finish with a 1/8" NPT port at each end. Use the 10 PSI residual valves for drum brake applications only. Use 2 PSI for disc brake applications. 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.

• (1) Drum Brake Residual Valve, 10 PSI
