Condition/Concern

Some customers may comment on a clicking noise emanating from either the front or rear wheels location. This condition may be more predominate at low speeds (10-20 mph or 16-32 km/h) during full wheel lock turns on dry clean pavement. The clicking noise is generally noted as approximately 1 to 4 clicks per wheel revolution.

This may be caused by interaction between the wheel mounting face and the wheel mounting surface on the brake rotor.
