• NOTE: Adjustable proportioning valves can be used to supplement dynamic bias control when less bias may be desired at
lower pressures, but higher bias is desired at higher pressures. When using a proportioning valve in conjunction with a
balance bar, all initial testing should be done with the proportioning valve adjusted out of range. Knob type proportioning
valves should be adjusted fully clockwise tight and lever type adjusting valves should se set at the high cam position allow
full brake pressure flow throughout the entire pressure range. Once a balanced medium to med-high bias setting is achieved
with the balance bar, testing and adjustment of the proportioning valve can be used to provide additional control during
intermittent high brake pressure cycles.
• The balance bar should initially be centered to establish a baseline. It is centered when an equal amount of the threaded rod is
protruding from the clevises on both ends. This must be measured before installing the adjuster knob or remote cable. Pressure testing
gauges can also be used to determine and monitor balance bar settings
• For vehicles with equal sized master cylinders, the pressure readings will be equal when the balance bar is centered. For vehicles with
unequal sized master cylinders, use the baseline chart below to determine your centered balance bar position.
Bore Size 1 1/8” 1” 7/8” 13/16” 3/4" 5/8”
Pressure 242 306 400 464 544 783
• EXAMPLE: For a vehicle equipped with a combination of a 7/8” and 1” master cylinder, when the pedal is depressed with sufficient
force to generate 400 PSI by the 7/8” master cylinder, the gauge for the 1” cylinder should read at 306 PSI. This represents a centered
balance and equal load to each. There should now be an equal amount of adjustment in both directions from center.
• RACER”S NOTE: Record and monitor adjusted pressures after each event to help keep track of your preferred bias settings. If you are
unable to achieve the proper bias settings within the range of the bar adjustment, differently sized master cylinders or caliper piston
sizes may be necessary.
