Generally, you want braking to be even between the front and rear wheels. However, as you make changes via upgrades and other tuning, you may offset the balance of braking. If you find that the vehicle tends to understeer or oversteer under braking, you may have a braking imbalance.
You can correct for some amount of braking oversteer by moving the braking balance forward. Conversely, you can correct some understeer by moving the braking balance rearward. Too much braking balance to the rear, however, will upset stability under braking, while too much forward braking will contribute to understeer. Look for a neutral balance in the braking so that you feel neither understeer nor unsteady oversteer under hard braking conditions.
