This is a Technical Service Bulletin that was sent to dealers. This bulletin instructs dealers to how to fix a condition of a metallic knocking sound coming from the rear brakes. Affected vehicles experience this condition when the brake is applied while driving at low speeds, or on driving on uneven roads. Dealers are instructed to replace the rear brake pad clips (upper and lower) with new parts on affected vehicles, and to apply grease between the brake pad and caliper support.
