## Discrepancy

ENROUTE, THE CREW RECEIVED A EMERGENCY PARKING BRAKE PRESSURE LOW CAS MESSAGE.  THE CREW FOLLOWED THE QUICK REFERENCE HANDBOOK AND DIVERTED TO ITH.  THE AIRCRAFT WAS THEN FERRIED TO DAY.  MAINTENANCE INSPECTED AND FOUND THE EMERGENCY ACCUMULATOR PRESSURE LOW.  MAINTENANCE THEN SERVICED THE EMERGENCY ACCUMULATOR IN ACCORDANCE WITH DORNIER MAINTENANCE MANUAL 12-00-00.  OPERATIONAL CHECKS WERE PERFORMED AND THE AIRCRAFT WAS RELEASED FOR SERVICE.
