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.
    • Worn 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 1 side if the front suspension is not aligned correctly. This will be very noticeable if the caster and the camber are not within specifications.
