CAMPAIGN:PARKING BRAKE LEVER MAY NOT HOLD-REPLACE
MODELS/YEARS: 1987 FIRENZA MODELS
CONDITION:
---------
General Motors has determined that certain 1987 Oldsmobile Firenza models fail to conform to the requirements of Federal Motor Vehicle Safety Standard (FMVSS)105: "Hydraulic Brake Systems." These vehicles might have been assembled with parking brack lever mechanisms which will not properly engage when applied.
In some of these vehicles, the parking brake can be applied and appear to be proplerly engaged and later, when the vehicle is unattended, it could disengage. If the transmission were neither in gear (manual transmission) nor in Park (automatic transmission) the vehicle could unexpectedly roll. In such an instance the vehicle might roll away uncontrolled, which could result in a vehicle crash without prior warning.
To correct this condition, dealers are to replace the parking brake lever assembly as outlined in the service procedure section of this bulletin.
VEHICLES INVOLVED
Involved are certain 1987 Oldsmobile Firenza Models within the following VIN breakpoints:
Assembly Plant Beginning Up To And Including -------------- --------- ------------------- Leads (K) Start of Production HK300356
NOTE: Some of the subject vehicles within the breakpoints listed above were corrected at the assembly plant prior to being shipped to the dealer and will not require correction by the dealer. All subject vehicles which are listed on the dealer's campaign printout will require correction as outlined in the Service Procedure Section of this bulletin.
Should a question exist concerning the campaign involvement of a specific vehicle(s) within the breakpoints listed above, dealers should call the Computerized Recall Information System (C.R.I.S) for verification.

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.
