## Discrepancy

CREW REPORTED THAT THE BRAKES WORKED INTERMITTENTLY ON TAXI.  A FEW MINUTES INTO THE TAXI, THE PEDALS WERE FIRM BUT BRAKING ACTION WAS MINIMAL OR NON-EXISTENT.  CREW RETURNED TO THE FBO.  MAINTENANCE CHECKED IT OUT - BLED THE BRAKE SYSTEM, SERVICED THE HYDRAULIC RESERVOIR AND INSPECTED THE BRAKES.  MAINTENANCE AND CREW PERFORMED A TAXI CHECK AND THE BRAKING SYSTEM FUNCTIONED NORMALLY.
