Recall - Parking Brake Lever Assembly Inspection: Overview

9218oldsmobile02

Number: 92-C-02

Date: October 1991

Section: 5C


Subject:
PARKING BRAKE LEVER ASSEMBLY

Models/Years:
CERTAIN 1991 NINETY EIGHT
AND 1992 EIGHTY EIGHT MODELS


CONDITION

General Motors has determined that certain 1991 Oldsmobile Ninety Eight and 1992 Oldsmobile Eighty Eight model vehicles fail to conform to Federal Motor Vehicle Safety Standard 105, "Hydraulic Brake Systems", which, in part, covers parking brake performance. Some of these vehicles have parking brake lever assemblies which when applied can release one or more teeth. If release occurs, the cable load applying the rear brakes will be reduced, and depending upon the extent of lever release, the parking brake may not hold the vehicle as required.

To prevent this condition from occurring, dealers are to inspect, and, if required, replace the parking brake lever assembly.


VEHICLES INVOLVED

Involved are certain 1991 Oldsmobile Ninety Eight and 1992 Oldsmobile Eighty Eight model vehicles equipped with Parking Brake Lever Assemblies with date codes A1091, A1121, A1221, A1231, A1261, A1271, A1281, A1291, and A1301, within the following VIN breakpoints:

NOTE: Some of the subject vehicles within the breakpoints listed above were corrected at the assembly plants prior to being shipped to dealers and will not require inspection by the dealer. All subject vehicles which are listed on the dealer's campaign printout will require inspection, and, if necessary, replacement of the Parking Brake Lever Assembly as outlined in the SERVICE PROCEDURE section of this bulletin. If there is a question regarding the campaign involvement of a vehicle within the above breakpoints which is not listed on the dealer's printout, please inquire to the Vehicle Information Service System (VISS).

NOTE: There are an estimated 7941 vehicles involved within the VIN ranges above. It is expected that about half of these will require replacement of the Parking Brake Lever Assembly.


DEALER ACTION

Whenever a vehicle subject to this campaign is taken into your new or used vehicle inventory, or it is in your dealership for service, dealers are to ensure the campaign correction has been made before selling or releasing the vehicle.
