External Conditions That Affect Brake Performance

Tires - Tires having unequal contact and grip on the road will cause unequal braking. The tires must be equally inflated and the tread pattern of the right and left tires must be about equal.

Vehicle Loading - When the vehicle has unequal loading, the most heavily loaded wheels require more braking power than the others.

Front Wheel Bearings - Loose front wheel bearings permit the disc to tilt and have spotty contact with the linings causing erratic action.

Front End Alignment - Misalignment of the front end, particularly camber and caster, will cause the brakes to pull to one side.
