## Discrepancy

ECAM HOT BRAKES, RT BRAKES AT 480 & DRAGGING.  BOTH NR 3 & NR 4 BRAKES WERE SMOKING & DRAGGING DURING TAXI.  REPLACED DUAL ALTERNATE BRAKE DISTRIBUTION VALVE IAW MM & REPLACED ALTERNATE BRAKE SERVO VALVE MANIFOLD IAW MM.  BLEED BOTH ALTERNATE & NORMAL BRAKE SYSTEMS.  COULD NOT DUPLICATE FAULT, OPS CHECKED GOOD.
