AIR BRAKE SUPPLY LINES ARE REVERSED AT THE BRAKE TREADLE VALVE. THIS CAN CAUSE THE MODULATED SPRING BRAKE FEATURE ON THE REAR AXLE BRAKE TO BE INOPERABLE. IN THE EVENT THE REAR BRAKE SUPPLY RESERVOIR WERE LOST, THIS COULD RESULT IN LOSS OF BRAKES WITHOUT PROPER FUNCTION OF THE MODULATED SPRING BRAKE ACTION OF THE REAR BRAKE AXLE TO STOP THE VEHICLE.
LOSS OF THE SECONDARY SPRING BRAKE FUNCTION COULD RESULT IN A VEHICLE ACCIDENT IF THE PRIMARY AIR BRAKES FAIL.
VEHICLE OWNERS WILL BE INSTRUCTED TO SWAP SUPPLY LINES AT THE TREADLE VALVE TO OBTAIN THE CORRECT PLUMBING, AND WILL BE REIMBURSED FOR LABOR EXPENSES.
