## Discrepancy

ACFT RETURN TO BASE WITH PILOT COMPLAINING OF BRAKE GRABBING AND A NOISE FROM LT MAIN.  WHEEL ASSY REMOVED TO EXAMINE THE BRAKE UNIT.  BRAKE PADS AND DISC SHOWED VISUAL SIGNS OF WEAR, CUPPING OF BRAKE PADS AT BOTH ENDS OF SOME OF THE PADS.  THE WARP PADS WHEN HEATED CAUSE THE BRAKE UNIT TO DRAG.  THE BRAKE UNIT WAS REPLACED WITH A SERVICEABLE UNIT.  NOTE: O/H TIME IS SET TO 1400 LANDING FOR THIS TYPE OF BRAKE UNIT.
