The defect
THE REAR BRAKE LINE MAY HAVE BEEN IMPROPERLY ROUTED TO THE MAIN AIR TANK. SHOULD A MAJOR AIR LEAK DEVELOP IN THE REAR BRAKE SYSTEM, THE VEHICLE WOULD FAIL TO COMPLY WITH THE REQUIREMENTS OF FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 121, "AIR BRAKE SYSTEMS". THIS WOULD CAUSE THE ENTIRE BRAKE SYSTEM TO VENT TO THE ATMOSPHERE AND BRAKING EFFECTIVENESS WOULD BE LOST.
The remedy
THE DEALER WILL PROPERLY ROUTE THE AIR BRAKE LINE TO THE MAIN AIR TANK, IF NECESSARY, AT NO COST TO OWNER.
