Inspection and Verification (Start Testing Here)

NOTE: Prior to performing any diagnosis, make sure that the brake system warning indicator is functional.

Visually examine the front and rear tire and wheel assemblies for damage such as uneven wear patterns, tread worn out or sidewall damage. Verify the tires are the same size, type and, where possible, same manufacture. Any wheel or tire that is damaged or excessively worn should be replaced.
Wheels and tires must be cleared of any foreign matter and fire pressures adjusted to the correct specification.
If tires exhibit uneven wear or feathering, the cause must be corrected. Check steering and suspension components for damage or wear and, if necessary, check and adjust front wheel alignment.
