GM Service Manual Online
For 1990-2009 cars only
    • Tires with unequal contact and unequal grip on the road will cause unequal braking.
       - The tires must be equally inflated.
       - The tread pattern of the right-hand tire and the left-hand tire must be almost equal.
    • When the vehicle is loaded unequally, the most heavily loaded wheels require more braking power than the other wheels.
    • Loose front wheel bearings may cause the following:
       - Brake rotor tilt
       - Spotty contact with the brake linings
       - Erratic braking action
    • The brakes will pull the vehicle to one side if the front suspension is not aligned correctly. This will be very noticeable if the caster and the camber are not within specifications.
