Preliminary Inspection

NOTE: Before carrying out 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 renewed.

Wheels and tires must be cleared of any foreign material and tire pressures adjusted to the specification.

If the tires exhibit uneven wear or feathering, the cause must be corrected. Check the steering and suspension components for damage or wear and if necessary, check and adjust front wheel alignment.
