The defect
THE FRONT AIR BRAKE HOSE MAY CONTACT THE INNER FENDER ON THE LEFT AND/OR RIGHT SIDES OF SOME TRUCKS. IN SOME INSTANCES, THE BRAKE HOSE MAY RUB THROUGH, RESULTING IN A LOSS OF AIR PRESSURE UPON BRAKE APPLICATION. CONSEQUENCE OF DEFECT: BRAKE HOSE MAY RUB THROUGH CAUSING AIR PRESSURE LOSS WHEN BRAKES ARE APPLIED AND REDUCED BRAKING ABILITY. A REDUCTION OF BRAKING ABILITY AT A TIME WHEN MINIMUM STOPPING DISTANCE IS REQUIRED COULD RESULT IN A VEHICLE CRASH WITHOUT PRIOR WARNING.
The remedy
INSTALL NEW BRAKE CHAMBER SUPPORT BRACKETS, BRAKE LINE ELBOWS, AND AIR BRAKE HOSES, AS NECESSARY.
