Proportioning valves are normally installed in the rear fluid line to prevent the rear wheels from locking before the front wheels, or to give a driver the ability to make fine adjustments in front to rear bias percentage on the track to compensate for tire wear, fuel load burn-off, or changing track conditions. It is generally not recommended to attempt to reduce front wheel braking capacity.
Do not attempt to operate the vehicle until the system has been fully tested under controlled conditions in a safe location. After the system has been bled, checked for leaks, and the proper pedal resistance and travel have been determined, make a series of low speed stops, then gradually progress to normal operating speeds.
Adjustable proportioning valves are designed for tuning and balancing custom brake systems on performance, racing, and other types of special purpose vehicles. They are not designed as direct replacements for any OEM application.57.38Brand: Wilwood Part Number: 260-12627
