## Discrepancy

DURING A MAINTENANCE RUN-UP AND SUBSEQUENT TAXI, THE BRAKES LOCKED UP AND THE AIRCRAFT COULD NOT BE MOVED.  BRAKE PRESSURE WAS RELIEVED AT THE BRAKE ASSY AND WAS FOUND THE NR 1 BRAKE MASTER CYLINDER HAD MALFUNCTIONED AND CAUSED THE BRAKES TO LOCK UP.  REFERENCE AD 2002-08-02 ISSUED FOR THIS PROBLEM.  THIS AIRCRAFT IS IN COMPLIANCE WITH THIS AD.
