External Conditions That Affect Brake Performance

TIRES
Tires having unequal contact and grip on road will cause unequal braking. Tires must be equally inflated, identical in size, and the tread pattern of right and left tires must be approximately equal.

CAR LOADING
When a car has unequal loading, the most heavily loaded wheels require more braking power than others. A heavily loaded car requires more braking effort.

WHEEL ALIGNMENT
Misalignment of the wheels, particularly in regard to excessive camber and caster, will cause the brakes to pull to one side.
