The problem
THE INVOLVED VEHICLES WERE ASSEMBLED WITH INCORRECT PLUMBING OF THE COPPER BRAKE APPLICATION VALVE SUPPLY AIR LINES. THIS CONSTITUTES A NON-COMPLIANCE TO FEDERAL MOTOR VEHICLE SAFETY STANDARD NO 121, "AIR BRAKE SYSTEMS". AS A RESULT, AIR COULD LEAK FROM THE REAR BRAKE SYSTEM.
What owners should do
DEALER WILL INSPECT AND RECONNECT ANY IMPROPERLY CONNECTED AIR LINES AT THE BRAKE APPLICATION VALVE, WITHOUT CHARGE.
