## Discrepancy

(CAN) DURING A SCHEDULED REPLACEMENT OF THE FLEXIBLE BRAKE HOSES, IT WAS NOTICED THAT THE END FITTING NUT WAS CRACKED ON THE RT HOSE BEING REMOVED.  THE CRACKED NUT WAS AT THE OPPOSITE END OF THE MASTER CYLINDER ATTACHMENT WHERE THE HOSE ATTACHES TO THE AN837-3D FITTING AND BRAKE LINE.  THERE WAS NO EVIDENCE OF LOOSENESS OR LEAK.  THE HOSE WAS REPLACED WITH THE NEW PART AS INTENDED.
