Balance Bar adjustment
The balance bar is an adjustable lever (usually a threaded rod), that pivots on a spherical bearing and uses two
separate master cylinders for the front and rear brakes. Most balance bars are part of a pedal assembly that also
provides a mounting for the master cylinders. When the balance bar is centered, it pushes equally on both
master cylinders creating equal pressure, given that the master cylinders are the same size bore. When adjusted
as far as possible toward one master cylinder it will push approximately twice as hard on that cylinder as the
other.
To set up the balance bar, thread the master cylinder pushrods through their respective clevises to obtain the
desired position. Threading one pushrod into its respective clevis means threading the other one out the same
amount.
Sometimes this will lead to a “cocked” balance bar when the pedal is in the relaxed position, “no pedal effort”.
This is acceptable as long as each master cylinder pushrod is completely free of pressure when the pedal is
relaxed.

The pushrod adjustment depicted in the figure is representative of a typical asphalt application. That is,
large caliper pistons in front, small caliper pistons in the rear.
It is important that the operation of the balance bar functions without interference by over adjustment. This can
occur when a clevis jams against the side of the pedal or the lever (bolt) hits the pedal bore during any point of
pedal travel interference.
