Recall - Rear Brake Line Routing
Product Safety - Rear Brake Line Routing # 04086 - (Jan 11, 2005)
Models:
2004-2005 Cadillac XLR
2005 Chevrolet Corvette
Condition
General Motors has decided that a defect, which relates to motor vehicle safety, exists in certain 2004 and 2005 model year Cadillac XLR vehicles, and
2005 model year Chevrolet Corvette vehicles. The rear brake lines may contact other components or be affected by heat from them.
If contact occurs, the driver may hear a rattle noise. Over time, the contact could cause brake line wear-through resulting in a slow loss of brake fluid,
which would appear as fluid spotting under the vehicle. On XLR vehicles, this could also create a visible puff of smoke when the brakes are applied. If
enough fluid is lost, the performance of the rear brakes will be reduced, there would be an increase in brake pedal effort in order to achieve the desired
braking, and the brake system warning light may illuminate on the instrument panel.
If the brake line on XLR vehicles is affected by heat, the fluid in the brake line could boil. The performance of the rear brakes will be reduced and there
would be an increase in brake pedal effort in order to achieve the desired braking.
If this were to occur when stopping distance is limited, a crash could occur.
Correction
Dealers are to inspect, and reposition or secure if necessary, the rear brake lines to ensure that there is adequate clearance from other underbody
components. On some vehicles, a machining tab on the rear differential housing may need to be removed to provide adequate clearance. The rear brake
lines are to also be inspected and, if damaged, repaired.
