## Discrepancy

CREW REPORTED THE BRAKES DIDN'T RELEASE FOR PUSHBACK.  MAINTENANCE FOUND NR 4 MAIN WHEEL NOT SPINNING FREELY.  MAINTENANCE REMOVED THE NR 4 WHEEL, FREED UP THE BRAKE ROTORS AND THEN RE-INSTALLED NR 4 MAIN WHEEL.  THE BRAKES THEN OPERATED NORMALLY, OPS CHECK GOOD PER EMB AMM 32-49-05.
