## Discrepancy

(CAN) AFTER LANDING, PILOT REPORTED THAT ACFT REQUIRED MORE POWER THAN NORMAL DURING TAXI TO GATE.  ACA INSPECTED WHEELS & BRAKES AND FOUND NR 4 BRAKE AND MAIN WHEEL ASSY WERE DAMAGED BEYOND REPAIR.  TIRE PRESSURE FOUND NORMAL, FUSE PLUGS DID NOT MELT.  THE DAMAGE DESTROYED BOTH THE NR 4 MAIN WHEEL ASSY AND THE BRAKE ASSY. IT IS SUSPECTED THAT THE DAMAGE WAS DUE TO A FAILED INNER WHEEL BEARING.  INNER BEARING FOUND TO BE DAMAGED AND SEIZED/WELDED TO THE AXLE.  OUTER BEARING WAS INTACT. THE FUSE PLUGS WERE NOT FUSED.  THE AXLE SHOWED SIGNS OF OVERHEATING. THE ACFT IS CURRENTLY AOG AWAITING REPLACEMENT PARTS.
