Balance Bar aDjustMent anD operation
When running on pavement, you want the front tires to lock-up with slightly less
pedal force than the rear tires. This will help to keep the car stable and prevent it from
going into a spin.
1. Loosen the jam-nut on the adjusting shaft (Item 3 in Diagram 10). A jam-
nut is not used with a remote adjuster.
2. Turn the adjusting shaft (Item 8 in Diagram 10) by hand or with the
remote cable adjuster so that it advances the spherical bearing closer
to the selected master cylinder, increasing the braking force produced
by that master cylinder (Diagram 9). The balance bar must be adjusted
with the pedal in the relaxed position (Diagram D). It will not rotate while
depressing the pedal.
3. The balance bar has a fairly large adjustment range. However, if you find
that what you need is outside of the adjustment range, you will need
to make a master cylinder bore size change. There are three possible
changes that can be made (See below). All will allow the spherical joint to
move back towards the center position.
a) Decrease the bore size of the master cylinder closest to the
spherical joint by 1/8". This will decrease the amount of pedal force
required from the foot and increase the amount of pedal travel.
b) Increase the bore size of the master cylinder farthest from the
spherical joint by 1/8". This will increase the amount of pedal force
required by the foot and decrease the amount of pedal travel.
c) Increase the bore size of the master cylinder farthest from the
spherical joint by 1/16". Decrease the other master cylinder bore
size by 1/16". This will maintain the amount of force and pedal
travel while making a relatively large change to the front/rear
brake bias.
4. Whenever making an adjustment, remember to tighten the jam-nut (Item
3 in Diagram 10) afterwards. A jam-nut is not required when a Remote
Brake Bias Adjuster is used.
