Inline Residual Brake Pressure Valves for F2’s ,Superstox ..or fact anything that needs braking control of individual wheels!
Maintains line pressure after first initial braking on any wheel(s) where fitted.
Greatly aids turning under braking
Especially ideal where brake master cylinder is located below the horizontal plane of brake calipers (eg RCE’s).
These residual pressure valves retain a minimum brake line pressure to help eliminate excessive pedal travel in both disc and drum brake systems or to provide staggered/early braking to specific wheels to enable controlled twisting/turning of the car under braking.
This instant effect cannot be produced by proportion valves as the initiation pressure of most popular design prop values commences only when a line pressure of 200 PSI is reached (the 30/70% split point) – multiple expensive prop valves would be required to reproduce this effect on individual wheels.
Available is 2 factory set pressure settings (2 PSI and 10 PSI)
The 2 PSI 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. With drum brake set ups, a 10 PSI valve is used to compensate for return spring tension and maintain wheel cylinder sealing in the drums.
Residual Pressure Valves are made from billet aluminum and color coded for easy identification.
