Balance Bar Set-Up

PURPOSE:
The function of a bias bar is to allow the adjustment of brake line pressure distribution between two master cylinders. This is accomplished through moving the bias bar pivot towards one master cylinder pushrod or the other. If the pivot is perfectly centered between the pushrods, the force applied to each master cylinder will be equal. This is known as the “neutral position” of the bias adjuster. If the pivot is moved closer to one pushrod or the other, then the master cylinders will receive differential pressures (proportional to the distance between the bias bar pivot point and master cylinder center lines). This adjustment gives the driver control over the braking characteristics of the car, and to alter those characteristics to account for changes in fuel load, track conditions and handling characteristics of the car.

Dyno Pre-Burnishing Policy

In some racing venues it has become commonplace to pre-burnish brake discs and pads on brake dynomometers. Although Performance Friction does provide this service, we do not recommend its necessity with our products.

When using Performance Friction discs with Performance Friction pads we found that dynamometer pre-burnishing is unnecessary, expensive and can be detrimental to the performance of the brake package. Resulting from extensive studies of various combinations of pads and discs (green and pre-burnished) we have measured the highest performance and most consistent braking is achieved using Performance Friction compounds that have undergone our “Race Ready” factory processing, as are all PFC pads in 01, 97, 93, 90, 83 and 80 compound.

The best way to ensure consistent performance from your brake system is to use the discs and pads as they are manufactured by Performance Friction, and bed them on the raceetrack.
