## Discrepancy

CREW REPORTED THAT DURING STATIC TAKEOFF, THE RT BRAKE FAILED MOMENTARILY AND A BRAKE DEGRADED EICAS MESSAGE APPEARED.  THE CREW ABORTED TAKEOFF AND RETURNED TO THE GATE WITHOUT INCIDENT.  MAINTENANCE REPLACED THE BRAKE CONTROL UNIT AND THE NR 4 WHEEL SPEED TRANSDUCER. OPS AND TAXI CHECKS WERE GOOD WITH NO FURTHER DEFECTS NOTED.
