Universal pedal assembly 2831. Also comes with compatible disc/drum proportioning valve kit (self adjusting valve, pre-bent lines for 1/2″ and 9/16″ master cylinder ports, bracket to mount kit to the side of the master cylinder, and bolts). The proportioning / combination valve performs all of the necessary valving functions with a disc brake conversion. As more force is applied to the brakes the car will begins to lean forward, less braking force is needed in the rear. This valve decreases the pressure to the rear which prevents them from locking up. Metering is used in the front disc brake portion in the disc/drum system to delay application of the front discs allowing the slower reacting drum brakes to catch up, which provides rear stability on wet surfaces that helps prevent front pad to wear. Drum Brakes require residual pressure of 10 lbs. To be held in the line. This pressure keeps the brake shoes close to the drums, giving you a more firm pedal feel. 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 compenstate 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. Note: Safety comes first. Any brake service should only be performed by persons experienced in the installation and proper operation of brake systems. It is the responsibility of the person installing any brake component or kit to determine the suitability for the particular application. After installation and prior to operating vehicle, brake function should be tested under controlled conditions. New items are being added daily. Track Page Views With. Auctiva’s FREE Counter.
