The adjustable proportioning valve is designed to be installed in the brake line, in order to adjust pressure in the brake system to keep the brakes from locking or engaging too soon.
Valve features:
The red in-line pressure valve retains a minimum brake line pressure to help eliminate excessive pedal travel in drum brake systems.
With drum brakes, a ten pound valve is used to compensate for return spring tension in the drums.
The blue in-line pressure valve retains a minimum brake line pressure to help eliminate excessive pedal travel in disc brake systems.
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.
Residual Pressure Valves are made from billet aluminum and color coded for easy identification. Ideal for drag racing, street rod, and many off road applications.
