## Discrepancy

SEA - FLIGHT 2372 - FLIGHT RETURNED TO GATE AFTER RECEIVING A NR 2 HYDRAULIC CAUTION WITH ASSOCIATED LOSS OF NR 2 HYDRAULIC QUANTITY.  USERS OF NR 2 HYDRAULICS BECAME INOPERATIVE.  HYDRAULIC PRESSURE FLUCTUATED BETWEEN 150 AND 2000 PSI.  MAINTENANCE INSPECTED THE AIRCRAFT AND FOUND THE NR 1 MAIN LANDING BRAKE LINE RUPTURED.  THE LINE WAS REPLACED AND OPERATIONAL CHECKS WERE GOOD.  THE AIRCAFT WAS RETURNED TO SERVICE.
