What this recall covers

NHTSA's campaign record, quoted as published

The defect

THE EXISTING INTERLOCK AIR BRAKE SYSTEM MUST GET ITS AIR SUPPLY DIRECTLY FROM THE PARKING BRAKE AIR SUPPLY CIRCUIT. SHOULD A COMPONENT FAILURE OCCUR IN THE INTERLOCK AIR SYSTEM, IT WILL DEPLETE THE AIR SUPPLY FROM THE PARKING BRAKE CIRCUIT.

The risk

DEPLETION OF AIR SUPPLY FROM THE PARKING BRAKE CIRCUITWOULD ALLOW THE BUS TO ROLL WITH THE PARKING BRAKE APPLIED. THIS COULDRESULT IN A VEHICLE ACCIDENT.

The remedy

RELOCATE THE AIR SUPPLY LINE FOR THE INTERLOCK SYSTEM SO THAT THE AIR SUPPLY COMES FROM THE PARKING BRAKE CIRCUIT TO ENSURE THAT WHEN THE PARKING BRAKE IS APPLIED, THE PARKING BRAKE CANNOT BE DISENGAGED OR OVERRIDDEN BY COMPONENT FAILURES.

Notes

SYSTEM: BRAKES.VEHICLE DESCRIPTION: 60 FOOT ARTICULATED BUSES.

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.
