Brake Residual Pressure Valve, Red Anodised, 10 psi, Drum Brakes , 1/8 in. NPT

10 psi, Drum Brakes, 1/8 in. NPT Female Inlet/Outlet

With drum brakes, 10 lb. valves are used (PFE393) to compensate for return spring tension in the drums

Ideal for drag racing, street rods, and many off-road applications, inline residual pressure valves from Proflow retain a minimum brake line pressure to help eliminate excessive pedal travel.

2 lb valves are used in disc brake applications where the master cylinder is mounted below the horizontal plane of the calipers--in other words, where fluid drain back occurs, causing excessive brake drag.

Proflow's residual pressure valves are made from billet aluminium and color-coded for easy identification.
