Summary of the Safety Concern:
IMPROPER ROUTING OF THE AIR BRAKE HOSES FROM THE BRAKE VALVES TO THE BRAKE CHAMBERS OF THE AIR OPERATED S-CAM BRAKES CAN CAUSE THE HOSES TO CHAFE OR BE CUT ON THE TRAILER FRAME. |

ALSO, IF A SPRINGBRAKE HOSE IS CUT, THE SPRING BRAKE DRAG OCCURS, WHICH REDUCES THE EFFECTIVENESSOF THE SERVICE BRAKES, AND CAUSES BRAKE COMPONENTS TO OVERHEAT TO THE POINT OFIGNITING THE UNDERCOATING AND BURNING THE TRAILER. THIS CAN ALSO CAUSE WHEELLOCKUP WHICH COULD RESULT IN A VEHICLE CRASH. |

|
Remedy:
CHAFFED BRAKE HOSES WILL BE REPLACED, AND THE BRAKE HOSE ROUTING AND BRAKE CHAMBER INSTALLATION WILL BE MODIFIED TO ELIMINATE THE BRAKE HOSE CHAFFING PROBLEM. |
