Q & A

What's in the Box

These in-line pressure valves retain a minimum brake line pressure to help eliminate excessive pedal travel in disc brake systems. Residual pressure valves are made from billet aluminum with 1/8" npt female threads for the inlet/outlet and color coded for easy identification. Ideal for drag racing, circle track, street rod and many off road applications.

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.

Disc Brake Residual Pressure Valve, 1/8 NPT, 2 PSI
SKU-91031340
                        

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 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.

Valve is 1/8" NPT male on the inlet side and 1/8" NPT female on the outlet side. Use 2 PSI residual valves for disc brake applications only.

Speedway Drum Brake Residual Valve, 10 PSI, Purple
SKU-91031347
                        

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 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 after the brake pedal is released. 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 10 PSI residual valves for drum brake applications only.
