What this recall covers

NHTSA's campaign record, quoted as published

The defect

THE QUICK RELEASE VALVE SUPPORT BRACKET MOUNTED ON THE AXLE MAY CRACK. THIS CAUSES FATIGUE FAILURE OF THE STEEL AIR LINES LEADING TO THE REAR PARKING BRAKES AND CHASSIS SERVICE BRAKES RESULTING IN SUDDEN LOSS OF AIR PRESSURE. CONSEQUENCE OF DEFECT: THIS SUDDEN LOSS OF AIR TO THE BRAKE CHAMBERS WILL RESULT IN AUTOMATIC ACTUATION OF REAR PARKING BRAKE CAUSING SUDDEN REAR WHEEL LOCKUP WHICH MAY CONTRIBUTE TO AN ACCIDENT.

The remedy

INSTALL A REDESIGNED VALVE SUPPORT BRACKET.

Notes

SYSTEM: PARKING BRAKES AIR LINES, QUICK RELEASE VALVE BRACKET.VEHICLE DESCRIPTION: MID-LINER TRUCKS.

A safety recall is issued when a manufacturer or NHTSA determines that a vehicle has a safety-related defect or does not comply with a federal motor vehicle safety standard. Recall repairs are free. Whether a specific vehicle is covered depends on its VIN — a recall listed for a model year does not necessarily apply to every vehicle of that year.
