## Discrepancy

CREW REPORTED THEY RECEIVED AN EMERGENCY BRAKE NOT RELEASED MESSAGE WHILE IN FLIGHT.  CREW DIDN'T DECLARE EMERGENCY BUT HAD FIRE TRUCKS ROLLED, AND LANDED WITHOUT INCIDENT AT CHS.  MAINTENANCE WAS DISPATCHED TO THE ACFT TO TROUBLESHOOT.  MX CLEANED & RESECURED THE EMERGENCY PARKING BRAKE PRESSURE SWITCH AND PERFORMED OPS CHECKS PER AMM.  ACFT WAS THEN RELEASED BACK INTO SERVICE.
