CAMPAIGN: ANTI-LOCK BRAKE HYDRAULIC UNIT MOUNTING BOLTS
MODELS/YEARS CERTAIN 1989 TORONADO AND TROFEO MODELS WITH ANTILOCK BRAKE SYSTEMS
CONDITION
General Motors has determined that a defect which relates to motor vehicle safety exists in some 1989 Toronado and Trofeo models equipped with the Anti-Lock Brake System (ABS). Involved vehicles may have one or both ABS hydraulic unit mounting bolts not properly seated. This condition could cause increased brake pedal travel and/or poor pedal feel if the attachment loosens. In addition, with time this condition could lead to separation of the ABS hydraulic unit from its mounting bracket. Separation would result in loss of brake function and could result in a vehicle crash without prior warning.
VEHICLES INVOLVED
All 1989 Toronado and Trofeo model vehicles equipped with the Anti-Lock Brake System (option code JL9) within the following VIN breakpoints:
Beginning Thru and Including --------- ------------------- KU300001 KU300532
There are 532 Toronados and Trofeos between the breakpoints, but only the 278 vehicles equipped with Anti-Lock Brake Systems are affected.
DEALER ACTION
To correct this condition, dealers are to replace both ABS hydraulic unit mounting bolts on all affected vehicles as per the VEHICLES INVOLVED and SERVICE PROCEDURE sections of this bulletin.
Dealers are to perform this campaign on all involved vehicles at no charge to owners, regardless of mileage, age of vehicle, or ownership from this time forward.
Whenever a vehicle subject to this campaign is taken into your new or used car inventory, or it is in your dealership for service, you are to ensure the campaign correction has been made before selling or releasing the vehicle.

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.
