INSTALLATION & ADJUSTMENTS 

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.
Use only the two .25" body holes to secure the valve to a mount. Do not attempt to remove the adjuster knob
or valve body end cap to facilitate thru-panel mounting.
The two ports are 3/8-24 inverted flare seats to adapt double flared hard brake lines directly to the valve.
Connect the "IN" port to the pressure line coming from the master cylinder. Connect the line going to the
calipers to the "OUT" port.
The adjusting knob is marked with an arrow indicating the direction required to decrease line pressure to the
calipers. The knob rotated all the way out (counter-clockwise) will provide a maximum pressure reduction of
57%. Rotating the knob in (clockwise) will incrementally increase line prressure, up to full pressure. If the
range of adjustment in the valve is not sufficient to properly balance the vehicle’s bias, changes to other
components within the system may be necessary.
TESTING THE SYSTEM - 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.
WARNING - 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.
