CAMPAIGN:BRAKE LINE MAY BE CONTACTING TRANS. BRACKET

U.S. Campaign Number Cross Reference

Olds 94-C-55

Models: 1993 and 1994 Oldsmobile Cutlass Supreme

TO: ALL GENERAL MOTORS DEALERS

General Motors of Canada Limited has determined that a defect which relates to motor vehicle safety exists in certain 1993-1994 Oldsmobile Cutless 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 the 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, dealers 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 1993-1994 Oldsmobile Cutlass Supreme vehicles built at Dorville Assembly Plant within the following VIN breakpoints:

Year Model Plant Plant Code From Through

1993 W - Cutlass Supreme Doraville D PD361085 PD383015 1994 W - Cutlass Supreme Doraville D RD300022 RD376332

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 10mm (7/16") do not reposition. Proceed to step #20.

LACK OF CLEARANCE

5. If clearance is found to be less than the minimum of 10mm (7/16"), inspect lines to determine if contact has been occurring with the transaxle 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 (and leave loose) 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 five (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 10mm (7/16"), lower the vehicle and proceed to step #20.

B. If the clearance to the transaxle bracket is still not at least 10mm (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 TBE 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 fine 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 six (6) brackets.

11. Remove the long rear portion of the line.

Before removing the short piece of the 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 to 6 foot piece of 8 to 10 gauge wire to die 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 two (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 the end of tube fitting to lessen die 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 to 27 N.m +/- 3 N.m (20 lb ft. +/- 2 lb. ft.) and rear fitting to 15 N.m +/- 3 N.m (I 1 lb. ft. +/- 2 lb. ft.).

17. Tighten bracket bolts.

18. Verify proper clearance of all lines as indicated in steps 5 through 7 above.

19. Bleed brakes per Service Manual procedures.

20. Install a Campaign identification Label.

INSTALLATION OF CAMPAIGN IDENTIFICATION LABEL

Clean surface of radiator upper mounting panel and apply a Campaign Identification Label. Make sure the correct campaign number is inserted on the label. This will indicate that the campaign has been completed.
