Brake force distribution (brake balance)

The GT3 Cup is fitted with a dual circuit brake system incorporating two
separate brake master cylinders. The front to rear brake balance ratio is
set by rotating the brake balance knob.
The brake balance adjustment is made via a balance-bar system. The
brake balance is adjusted by a potentiometer on the instrument panel.
Rotating the brake balance adjuster knob in the "-" direction increases the
brake pressure on the rear axle in comparison to the front. In the "+"
direction vice versa.
