## Discrepancy

AFTER ARRIVAL IN PHX EN ROUTE FROM LAS, FLIGHT CREW NOTICED HYDRAULIC FLUID WAS LOW ON QUANTITY GAUGE, FURTHER INSPECTION REVEALED DAMAGE TO NR 3 BRAKE ASSEMBLY.  IT APPEARS BRAKE ROD DISCONNECTED CAUSING NR 3 BRAKE TO ROTATE SHEARING HYDRAULIC LINES AND TEMPERATURE SENSOR WIRES.  NR 3 BRAKE ROD CONTACTED THE NR 7 BRAKE ROD DIRECTLY BEHIND IT CAUSING THE NR 7 BRAKE ROD TO BEND.  MAINTENANCE REMOVED AND REPLACED THE NR 3 BRAKE ASSEMBLY IAW T/C R4M32604.  REPLACED NR 3 AND NR 7 BRAKE RODS IAW BMM 32-11-19-4, AND REPLACED WIRING AND CONDUIT FROM JUNCTION BOX TO CONNECTOR D022656.  REMOVED AND REPLACED HYDRAULIC FLEX LINE PER T/C R4M32604, LEAK AND OPERATIONAL CHECKS WERE GOOD.
