The hazard

On certain trucks, the cotter pin which retains the brake slack adjuster’s clevis pin may have been omitted during vehicle assembly. As a result, the clevis pin could loosen and fall out, causing a loss of brake function at the affected wheel. This could cause the vehicle to pull to one side under braking, or increase stopping distance, which could result in a crash causing property damage and/or personal injury. Correction: Dealers will verify cotter pin installation on each brake slack adjuster. Replacement cotter pins and/or clevis pins will be installed as needed.
