RepairPal Expert Overview
On certain vehicles, the rear brake lines may be too close to the exhaust, which could heat the lines and cause the brake fluid to boil. If the brake fluid boils, effectiveness of the rear brakes would be reduced and a crash could occur.
Please contact your GM dealer. They will check to see if your specific vehicle is affected and advise you on what to do next. Always have your vehicle identification number (VIN) handy when you call.
On certain vehicles, the rear brake lines may be close, or come into contact with the exhaust manifold. This could heat the lines and boil the brake fluid; the lines could also wear from contact. If the brake fluid boils, or leaks, effectiveness of the rear brakes would be reduced and a crash could occur.
Dealers will inspect the left engine exhaust manifold clip for alignment and placement on the body mounted stud. If it's correct, they will reposition the clip on the brake lines and reinstall the clip on the stud. Dealers will ensure that both rear brake lines have the proper clearance to the left exhaust pipe and the machining tab on the rear differential housing will be removed. The brake lines in the affected areas will be inspected for damage and will be replaced if there are signs of wear-through on the nylon overcoating. The recall began January 18, 2005. The GM recall number is 04086.
