## Discrepancy

DURING THE TAKEOFF ROLL, THE NR 2 HYDRAULIC SYSTEM INDICATOR WENT TO ZERO.  CAUTION LIGHT DID NOT ILLUMINATE AND QUANTITY REMAINED STEADY.  TAKEOFF WAS ABORTED AT 75 KNOTS IAS.  MAINTENANCE REPLACED THE HYDRAULIC PRESSURE INDICATOR.  OPS CHECKS WERE GOOD AND THE AIRCRAFT WAS RELEASED FOR SERVICE.
