Defect Involved, Vehicle Involved, Dealer & Owner Information

DEFECT INVOLVED

General Motors has determined that a defect which relates to motor vehicle safety exists in certain 1991 K 1-2 pickup trucks built at Ft. Wayne assembly plant. These vehicles may have an incorrect front wheelhouse splash shield that may contact the rubber portion of the front brake hose, which could result in a sudden failure of the front hydraulic brake system. If this failure occurred, the rear brake system still functions, but increased stopping distance would be required. Loss of front braking at a time when minimum stopping distance is required could result in a vehicle crash, without prior warning.


To prevent this condition from occurring, dealers are to inspect all suspect "K" model vehicles for incorrect splash shields and replace them with the correct parts. Additionally, where there is an incorrect splash shield, the brake hose will be replaced.
