CAMPAIGN: REAR BRAKE DRAG WRONG SPRINGS. Chevrolet Celebrity 1983

For 1990-2009 cars

# CAMPAIGN: REAR BRAKE DRAG WRONG SPRINGS

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 an appointment 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 is being sent to owners, the owners are being instructed to contact the nearest Chevrolet Zone office if their dealer does not remedy the condition within five days of the mutually agreed upon service date. If the condition is not remedied within a reasonable time, they are instructed on how to contact the National Highway Traffic Safety Administra tion.

#### DEFECT INVOLVED

General Motors has determined that certain 1983 Celebritys fail to conform to the parking brake requirements of Federal Motor Vehicle Safety Standard 105-75, "hydraulic brake systems". The parking brake cables installed on these vehicles have incorrect return springs. When adjusted to specifications, the incorrect spring can cause rear brake drag. Rear brake drag can result in premature lining wear, overheating of the brake drums, grabbing or uneven brake action and poor fuel economy. When adjusted to eliminate rear brake drag, the parking brake will not meet the grade-holding requirements of FMVSS 105-75.

To prevent the possibility of this condition occurring, dealers are to install new rear parking brake cables on vehicles involved.

#### VEHICLES INVOLVED

The only vehicles involved are (11) 1983 Chevrolet Celebritys identified below:

2G1AW19X7D1814626 2G1AW19X8D1814943 2G1AW19X3D1814669 2G1AW19X9D1815020 2G1AW19R9D1814709 2G1AW19R8D1815026 2G1AW19X3D1814722 2G1AW19X5D1815009 2GlAW19X4D1814728 2G1AW19X8D1815056 2GlAW19X8D1814893

Involved vehicles have been identified by Vehicle Identification Number Computer Listings. Computer listings contain the complete Vehicle Identification Number, owner name and address data, and are furnished to the involved dealers with the campaign bulletin. Owner name and address data furnished will enable dealers to follow-up with owners involved in this campaign.

These listings may contain owner names and addresses obtained from State Motor Vehicle Registration Records. The use of such motor vehicle registration data for any other purpose is a violation of law in several states. Accordingly, you are urged to limit the use of this listing to the follow-up necessary to complete this campaign. Any dealer not receiving a computer listing with the campaign bulletin was not shipped any involved vehicles.

#### OWNER NOTIFICATION

Owners will be notified of this campaign on their vehicles by Chevrolet Motor Division (see copy of Owner Letter included with this bulletin).

#### DEALER CAMPAIGN RESPONSIBILITY

Dealers are to service all vehicles subject to this campaign 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 vehicle inventory, or it is in your dealership in the future, you should take the steps necessary to be sure the campaign correction has been made before reselling or releasing the vehicle.

Owners of vehicles recently sold from your new vehicle inventory are to be contacted by the dealer, and arrangements made to make the required modification according to instructions contained in this bulletin.

This bulletin is notice to you that the new motor vehicles included in this campaign may not comply with the standard identified above. Under Sections 108 and 114 of the National Traffic and Motor Vehicle Safety Act, it is illegal for a dealer to sell a new motor vehicle which the dealer knows does not comply with an applicable Federal Motor Vehicle Safety Standard.

As a consequence, if you sell any of these motor vehicles without first performing the campaign correction, your dealership may be subject to a civil penalty up to $1,000 for each such sale.

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.
