Brake balance is the ratio between front and rear braking force.
If brake balance is badly set, the 4 wheels will not brake at their maximum potential.
Since brake balance also influences the approach to a band, the more the balance is set to the rear, the more the rear brakes are likely to jam first, making the car over-steer.
In all cases, a car that locks its front wheels first is easier to steer than one that locks its rear wheels first. Because inertia is applied to the carÆs center of gravity, under deceleration, braking is accompanied by a transfer of vertical load, which tends to remove the burden from the rear axle and loads it onto the front. An axleÆs tire-to-ground adhesion limit is relative to the vertical load: the higher the load, the greater the grip and viceversa.
