## Discrepancy

ON LANDING ROLL OUT RT BRAKE IS GRABBING FOLLOWED BY A LOUD LONG "SQUEAK" AND VIBRATION.  ON POST FLIGHT INSPECTION, THE BRAKE IS VERY HOT AND SMOKING.   INSPECTED AND VERIFIED METERING VALVE WAS HITTING STOPS.   CHECKED BRAKE HYD PRESSURES ON THE LT AND RT BRAKES. BOTH SYS HAD 50 PSI WITH BRAKES DEPRESSED, AND NO RESIDULE PRESSURE. JACKED THE ACFT AND REMOVED THE RT WHEELS.  INSPECTED RT BRAKE ASSEMBLIES AND SAW NO OBVIOUS DEFECTS. REPLACED BRAKES
