## What is wrong

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.


## What can happen

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.
