The defect
THE AIR BRAKE LINES MAY BE ROUTED TOO CLOSE TO THE EXHAUST MUFFLER. BECAUSE THE AIR BRAKE LINES ARE MADE OF NYLON MATERIAL, HEAT FROM THE EXHAUST MUFFLER CAN WEAKEN THE BRAKE LINE TUBES, POSSIBLY CAUSING THEM TO RUPTURE. TUBE RUPTURE COULD RESULT IN LOSS OF AIR IN THE SECONDARY AIR BRAKE SYSTEM.
The remedy
NEW NYLON AIR BRAKE TUBES WILL BE INSTALLED AND REROUTED WITHOUT CHARGE TO OWNER.
