Wilwood Brake & Clutch Pedal Description - Manual (Page 4)

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, Figure 3.
Lever movement should be unimpeded throughout pedal travel. In the neutral position, clevis’s should have between .20” - .25”
total clearance between the side of the pedal. The large washers between the pedal and clevis should remain loose. Make
sure that the master cylinder pushrods remain true in relationship to the cylinder during entire pedal travel; pushrods should
not be pushing master cylinder pistons at an angle. See Figure 4. NOTE: In its non-depressed position, the pedal and
balance bar should allow the pushrod of the master cylinders to fully return. This can be checked by feeling pushrods for
very slight movement, not loose movement. Master cylinder pistons should be against the retaining snap ring (under boot).
Brake balancing can also be affected by changes made in the following:
1. Master cylinder size.
2. Caliper piston size.
3. Use of a proportioning valve.
A full understanding of the entire brake system is important to maximize brake system performance. Use of a balance bar
pedal assembly can enhance a brake system with the proper installation and adjustment.
