## Discrepancy

CREW REPORTED THAT ON LANDING THE CAPTAIN'S BRAKES SEEMED TO LOSE PRESSURE FOR APPROXIMATELY ONE SECOND AND THEN WOULD GRAB.  THE AIRCRAFT TAXIED TO THE GATE WITHOUT FURTHER INCIDENT.  MAINTENANCE REPLACED THE BRAKE CONTROL UNIT.  OPERATIONAL CHECKS WERE GOOD WITH NO FURTHER DEFECTS NOTED.
