CAMPAIGN:BRAKE LINE MAY BE CONTACTING TRANS. BRACKET

SUBJECT: BRAKE PIPE INTERFERENCE

YEARS: 1993 & 1994

MODEL: CUTLASS SUPREME

TO: All Oldsmobile Retailers

The National Traffic and Motor Vehicle Safety Act, as amended, provides that each vehicle 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 repair within sixty (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 included copy of the letter that is being sent to owners, the owners are being instructed to contact OCAN (Oldsmobile Customer Assistance Network) if their retailer does not remedy the condition within five (5) 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 Administration.

DEFECT INVOLVED

General Motors has determined that a defect which relates to motor vehicle safety exists in certain 1993 - 94 Oldsmobile Cutlass Supreme model vehicles. The brake lines on some of these vehicles may be contacting the transaxle mounting bracket or frame side rail. This condition can cause the brake line to wear through, resulting in loss of brake fluid and eventual loss of one half of the vehicle braking system. If this condition were to occur in a situation where stopping distances were minimal, a vehicle crash could occur without prior warning.

To prevent the possibility of this condition from occurring, retailers are to inspect for proper brake line clearance and reposition those brake lines found to have less than minimal clearance. Additionally, those brake lines found to have an indentation caused by the contact will be replaced.

VEHICLES INVOLVED

Certain (not all) 1993 - 1994 Oldsmobile Cutlass Supreme vehicles built at the Doraville Assembly Plant within the following VIN breakpoints:

VIN THROUGH & YEAR MODEL MODEL NAME PLANT BEGINNING INCLUDING ---------------------------------------------------------------------------- 1993 W CUTLASS SUPREME D PD361085 PD383005 1994 W CUTLASS SUPREME D RD300022 RD376332

Not all vehicles between the above VIN breakpoints are involved.

Involved vehicles have been identified by Vehicle Identification Number listings. Computer listings contain the complete Vehicle Identification Number, owner name and address data, and are furnished to involved retailers with the campaign bulletin. Owner name and address data furnished will enable retailers 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 retailer not receiving a computer listing with the campaign bulletin has no involved vehicles currently assigned.

Should a question arise concerning the campaign involvement of a specific vehicle(s) within the breakpoints listed above, retailers should access the VISS (Vehicle Information Service System) for verification.

PARTS INFORMATION

It is anticipated that approximately less than one percent (1%) of the suspect brake pipes will require replacement for this condition. Therefore, please do not order parts for shelf stock. Only order parts when truly in need. Parts required to complete this campaign are to be obtained from GMSPO (GM Service Parts Operations). To ensure these parts will be obtained as soon as possible, they should be ordered from GMSPO on a V.I.P. order, with NO special instruction code, but order on an advise code (1).

DESCRIPTION PART NUMBER QUANTITY/VEHICLE ------------------------------------------------------------------ Brake pipe, Left front 10152241 As required Brake pipe, Left rear 10152263 As required Brake pipe, Right rear 10152264 As required Fluid, Brake 1052542 As required

OWNER NOTIFICATION

Owners will be notified of this recall on their vehicles by Oldsmobile Division (see copy of the owner letter included with this bulletin).

RETAILER CAMPAIGN RESPONSIBILITY

All unsold new vehicles in retailers' possession and subject to this campaign MUST be held and inspected/repaired per the service procedure of this campaign bulletin before owners take possession of these vehicles. After campaign is completed, the vehicle may be released for sale/delivery.

Retailers 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.

Owners of vehicles recently sold from your new vehicle inventory with no owner information indicated on the retailer listing are to be contacted by the retailer, and arrangements made to make the required correction according to the instructions contained in this bulletin. This could be done by mailing to such owners a copy of the owners letter included in this bulletin. Campaign follow-up cards should not be used for this purpose, since the owner may not as yet have received the notification letter.

In summary, whenever a vehicle subject to this campaign is taken into your new or used vehicle inventory, or it is in your retail facility for service in the future, please take the steps necessary to be sure the campaign correction has been made before selling or releasing the vehicle. Your cooperation in completing this campaign as soon as possible will be greatly appreciated.

SERVICE PROCEDURE

(Refer to Figure 1)

1. Turn steering wheel to the full right position.

2. Raise vehicle.

3. Inspect brake lines at rear of transaxle mount bracket for lack of proper clearance or contact with the bracket.

4. If clearance is greater than 1Omm or (7/16") do not reposition and proceed to step 20.

LACK OF CLEARANCE

5. It clearance is found to be less than the minimum of 1Omm or (7/16"), inspect lines to determine if contact has been occurring with the transmission bracket.

A. If no contact was made or the line only appears shiny (polished), it will only be necessary to reposition the line. (Proceed to Step #6).

B. If an indentation was worn into the line, it will be necessary to replace the line and reposition the bundle as required. (Proceed to Step #8).

6. Remove the five (5) screws holding the bundle clips to the under body and the inner fender.

7. Pull the bundle as far rearward in the car as it will go (this may be accomplished by inserting a board between the stabilizer bar and the 5 lines) and slide the clip that is by the front of dash forward on the lines until the rear of the bracket slot bolt hole lines up with the hole in the body. Re-bolt the clip to the under body. Slide the other brackets forward and install their bolts.

A. Recheck the clearance between the transmission bracket and brake lines - if the clearance is greater than 1Omm or (7/16") lower the vehicle and proceed to step 20.

B. If the clearance to the transmission bracket is still not a least 1Omm or 7/16", reposition the lines to obtain adequate clearance.

NOTICE: When repositioning, care must be taken not to kink, dent, or otherwise damage the lines. Gently reposition the lines by hand or, if a mechanical device is used, make sure it does not have any sharp edges or corners that could damage the metal lines.

LINE REPLACEMENT

IF THE CONTACT HAS RESULTED IN AN INDENTATION IN THE SURFACE OF THE LINE THAT CAN BE FELT WITH A FINGER NAIL OR SCREWDRIVER EDGE, THE LINE (FROM MASTER CYLINDER TO JUNCTION FORWARD OF FUEL TANK) NEEDS TO BE REPLACED.

8. Remove the five (5) bracket attaching bolts, and disconnect both ends of the line to be replaced.

USE NECESSARY PRECAUTIONS TO CONTAIN AND AVOID SPILLING THE BRAKE FLUID.

9. Cut the line between the front-of-dash and the transaxle bracket to make it easier to remove the damaged line.

10. Carefully pry the line out of the 6 brackets.

11. Remove the long rear portion of the line.

BEFORE REMOVING THE SHORT PIECE OF LINE, MAKE NOTE OF HOW IT IS POSITIONED RELATIVE TO THE OTHER LINES, ETC. SO IT WILL BE REINSTALLED CORRECTLY.

12. For improved access, disconnect the fuel line vent hose and ABS connectors to modulator.

13. Attach a 5-6 foot piece of 8-10 gauge wire to the front piece of tubing at the master cylinder, and remove it from the underside of the vehicle. This will "thread" the wire through the position where the existing line runs. (This will help mark the position for installing the new line and help guide it into position.

14. Use 2 technicians to install the line. (Optional):

A. One to guide the line from above with the wire.

B. One to carefully install the line from below the vehicle.

NOTE: Carefully, start of tube fitting to reduce the chance of "cross-threading.

15. Reinstall the lines into the five (5) under-body brackets (leaving brackets loose).

16. Tighten forward pipe fitting to master cylinder @ 27 NM +/-3NM (20 LB ft.+/-2 lb. ft.) and rear fitting to fitting @ 15 NM +/-3 NM (1 I lb. ft. +/-2 LB ft).

17. Tighten bracket bolts.

18. Verify proper clearance of ALL LINES as indicated in Step 5 through 7 above.

19. Bleed brakes per service manual procedures.

20. Install a Campaign Identification Label.

CAMPAIGN IDENTIFICATION LABEL

Each label provides space to print the campaign number and the five (5) digit retailer code of the retailer performing the campaign. Insert this information with a typewriter or ball-point pen. When installing label, clean and dry the surface of the radiator support tie bar and apply the campaign label where it is readily visible. Each Campaign Identification Label is to be located on the radiator core support in an area which will be visible when the vehicle is brought in for periodic servicing by the owner.
