CAMPAIGN:PARKING BRAKE LEVER MAY NOT HOLD-REPLACE. Buick Skyhawk 1987

For 1990-2009 cars

# CAMPAIGN:PARKING BRAKE LEVER MAY NOT HOLD-REPLACE

#### TO: ALL GENERAL MOTORS DEALERS

General Motors of Canada has determined that certain 1987 Oldsmobile Firenza and Skyhawk models fail to conform to the requirements of Canada Motor Vehicle Safety Standard 105, "Hydraulic rake Systems". These vehicles might have been assembled with parking brake lever mechanisms which will not properly engage when applied.

In some of these vehicles, the parking brake can be applied and appear to be properly 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.

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.
