General Installation, Assembly, and Adjustment Instructions
• Prior to installing the mount in the race car, or attaching the master cylinders, adjust the clevis to pivot side clearance as shown in
Figure 2. The combined total clearance of A + B should be approximately 3/16”. This is the equivalent of tightening the clevises to
remove all play, and then backing them off 4-5 turns. This adjustment is necessary to allow free movement of the balance bar through
full pedal travel with the master cylinder pushrods in a parallel position to each other.
•The master cylinder mount must be securely attached to a rigid element in the chassis. There should be no movement or deflection at
the mount when high pedal effort is applied. The master cylinders can be attached to the balance bar mount before or after it is installed
in the car.
• NOTE: Be sure to follow proper bench bleeding procedures when installing any new master cylinder. All air must be purged
from the master cylinder bore and piston chamber prior to attaching the pressure out lines. An effective bleed of the system
will be difficult, if not impossible to accomplish if the bench bleeding step is bypassed. Follow the instructions supplied with
the master cylinders for bench bleeding instructions.
• To attach the master cylinders to the balance bar mount, start by first threading the master cylinder pushrods into the clevises on the
balance bar. Keep the bolt holes in the mounting flanges aligned over the studs in the aluminum base, but don’t tighten them in place
yet. Thread the pushrods into the clevises until the tip of the pushrod bottoms out against the clevis pivot pins. Back the pushrods out
of the clevis 1/2 to 3/4 of a turn to eliminate any interference between the tip of the pushrods and the clevis pins. Snug the pushrod
jam nuts to temporarily secure their position. Final adjustment of the pushrod lengths will occur later in the installation process. Once
the pushrods have been installed into the clevises, the master cylinder mounting flanges can then be secured to the mount with the
nuts and washers supplied with the balance bar mount kit.
• Before installing the adjuster knob onto the top side of the threaded balance bar rod, rotate the balance bar clockwise until the balance
bar pivot bearing bottoms out against the lower master cylinder clevis. Thread the knob onto the balance bar until the tip is flush with
the upper outside edge of the top clevis. Lock it in place with the set screw inside the knob. This will provide approximately 3/8” of
thread engagement between the knob and threaded rod. If the adjuster knob is set too deeply, it will cause interference with the clevis
and prevent full range adjustability of the balance bar.

NOTE:
DIMENSION A + B TOGETHER SHOULD BE SET AT APPROXIMATELY 3/16”. THIS IS THE
ROUGH EQUIVALENT OF TIGHTENING ALL PLAY OUT FROM BETWEEN THE CLEVISES
AND PIVOT, AND THEN BACKING THEM OFF A COMBINED TOTAL OF 4-5 TURNS FOR THE
DESIRED CLEARANCE.
