CAMPAIGN: REAR BRAKE HOSE INTERFERENCE
U.S. Campaign Number Cross Reference: 95-C-28
THIS BULLETIN IS A REISSUE OF 5D02 ISSUED APRIL 1994. THE SERVICE PROCEDURE SECTIONS HAVE BEEN REVISED. SPECIFICALLY, THE INSPECTION INFORMATION HAS BEEN FURTHER CLARIFIED TO ASSIST IN PROPER DIAGNOSIS. PLEASE DISCARD ALL OLD COPIES OF BULLETIN 5D02.
Models: 1994-95 Buick Regal 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 1994-95 Buick Regal and 1994 Oldsmobile Cutlass Supreme model vehicles. The rear wheel brake hose(s) on some of these vehicles may be contacting rear suspension components. This condition can cause the brake hose(s) to wear through, resulting in loss of brake fluid and eventual loss 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 occurring, dealers are to inspect for proper rear brake hose position. Those rear brake hoses found in the incorrect position will be replaced with new hoses and correctly routed.
VEHICLES INVOLVED:
Involved are certain 1994-95 Buick Regal and 1994 Oldsmobile Cutlass Supreme model vehicles built within the following VIN breakpoints:

1. Raise vehicle on frame hoist and suitably support.
2. Inspect both (Right & Left) rear brake hoses for proper position (see Figure 1 and Figure 2).
3. If hose is properly positioned (shown in Figure 2), proceed to Step 16. If hose is incorrectly positioned (shown in Figure 1), proceed to Step #4.
INSPECTION (ON GROUND OR DRIVE-ON HOIST)
1. Position vehicle on drive-on hoist or leave on ground.
THIS METHOD OF INSPECTION MAY MAKE IT EASIER TO OBSERVE MISPOSITIONED HOSES.

3. If hose is properly positioned (hose is located rearward of the auxiliary spring mount bracket) proceed to Step 16. If brake hose is incorrectly positioned (contact or potential for contact exists) proceed to Step 4.
