The hazard

On certain vehicles, the slack adjuster housings may have been manufactured incorrectly, which could allow the housings to fracture and fail. As a result, the wheel brake to which the slack adjuster is attached would no longer function, which could increase vehicle stopping distances. Should a steer axle slack adjuster fail, it could also cause the vehicle to pull to one side during braking. Either problem could result in a crash causing property damage and/or personal injury. Correction: Dealers will inspect and, if necessary, replace the slack adjusters.
