## Discrepancy

CREW REPORTED THAT THEY RECEIVED A BRAKE OTBD INOPERATIVE CAUTION MSG WHEN THE LG WAS SELECTED DOWN. THE CREW DECLARED AN EMER.  THE ACFT LANDED WITHOUT INCIDENT & SAFETY CREWS INSPECTED THE BRAKE & FOUND THE ACFT SAFE TO TAXI TO THE GATE UNDER ITS OWN POWER.  MX REPLACED THE BRAKE CONTROL UNIT.  OPERATIONAL CHECKS WERE GOOD WITH NO FURTHER DEFECTS NOTED.
