## Discrepancy

DURING TAXI AWAY FROM GATE, FLUID WAS SEEN LEAKING FROM THE NR 1 MAIN LANDING GEAR ASSEMBLY.  IMMEDIATELY AFTER, THE NR 2 HYDRAULIC SYSTEM WENT INTO ISOLATION MODE.  BOTH HYDRAULIC SYSTEMS STILL HAD QUANTITIES DISPLAYED.  AIRCRAFT WAS TOWED TO GATE WHERE THE LEFT O/B FLEXIBLE BRAKE LINE WAS FOUND TO BE LEAKING.  REPLACED FLEXIBLE LINE AND WAS CHECKED AS GOOD WITH NO LEAKS.  BOTH HYDRAULIC SYSTEMS WERE SERVICED.
