CAMPAIGN: WHEELHOUSE SPLASH SHIELD MAY CONTACT BRAKE HOSE
SUBJECT: INCORRECT SPLASH SHIELD INSTALLED
MODELS: 1991 K 1-2 PICKUPS (FT WAYNE ONLY)
The National Traffic and Motor Vehicle Safety Act, as amended, provides that each vehicle which is subject to a recall campaign of this type must be adequately repaired within a reasonable time after the owner has tendered it for repair. A failure to adequately repair within 60 days after tender of a vehicle is prima facie evidence of failure to repair within a reasonable time.
If the condition is not adequately repaired within a reasonable time, the owner may be entitled to an identical or reasonably equivalent vehicle at no charge, or to a refund of the purchase price less a reasonable allowance for depreciation.
To avoid having to provide these burdensome solutions, every effort must be made to promptly schedule appointments with owners and to repair their vehicles as soon as possible. As you will see in reading the attached copy of the letter which is being sent to owners, the owner is being instructed to contact the nearest GMC Zone Office if the dealer does not remedy the condition within five days of the mutually agreed upon service date. If the condition is not remedied within a reasonable time, they are instructed how to contact the National Highway Traffic Safety Administration.
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 assem- bly 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.
VEHICLES INVOLVED
Involved are certain 1991 K 1-2 pickup trucks built at the Ft. Wayne assembly plant within the following VIN breakpoints.

Loss of front braking at time when mini- mum stopping distance is required could result in a vehicle crash, without prior warning.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition.
