## Discrepancy

PSC- DURING LANDING BRAKES WERE INITIALLY INEFFECTIVE, THEN BECAME VERY "GRABBY" AS IF ANTI SKID WAS CYCLING.  DURING POST FLIGHT INSPECTION, OBSERVED THAT BOTH OTBD BRAKES WERE VERY HOT BUT INBOARD BRAKES WERE COLD.  PLACED ANTI-SKID ON MEL 32-40-2.  CLEARED 3/15.  FOUND FAULT HISTORY RT INBD WST FLAGGED ON LEG 9 AND 11.  FOUND NR 3 WHEEL SPEED GENERATOR TURNING BY HAND, OPERATE ROUGHLY AND WOULD BIND.  REMOVED AND INSTALLED NR 3 WHEEL SPEED GENERATOR IAW TASK 32-46-11-000-801.  OP'S CHECK GOOD.  RETURNED TO SERVICE.
