CAMPAIGN:FRT. BRAKE CROSS PIPE BREAK- FEND. SKIRT CONTACT
MODELS: 1983-84 T15 LIGHT DUTY TRUCKS AND JIMMY
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 a service date with each owner and to repair their vehicle as soon as possible. As you will see in reading the attached copy of the letter which to being sent to owners, the owner is being instructed to contact the nearest GMC Zone Office if their dealer does not remedy the condition within five days of the agreed service date. If the oondition 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 some 1983-84 T15 Trucks. These trucks may have been assembled with the right front fender skirt contacting the brake pipe. Vibration of the fender skirt can eventually cause the pipe to break, resulting in a brake fluid leak and loss of the front brakes. These vehicles are equipped with a dual braking system; part of the system will still work and allow the vehicle to be stopped, but over a greater distance. Loss of front braking at a time when minimum stopping distance is required could result in a vehicle crash without prior warning.
To correct this condition, dealers are being requested to inspect and, if necessary replace the front brake crossover pipe on the suspect vehicles (right hand side) following the service procedure outlined in this bulletin.

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. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
