## Discrepancy

NO TAKEOFF CONFIG EICAS MESSAGE DUE TO PARKING BRAKE ON LIGHT REMAINED ILLUMINATED WITH PARKING BRAKE OFF. TAKEOFF CONFIG BUTTON STILL SAYS OK WHEN PRESSED.  EICAS MESSAGE APPEARS WHEN POWER LEVERS ARE AVANCED.   INSPECTED THE EMERGENCY BRAKE SYS IAW FIM 32-44-00-810-802A - 816-001A.  FOUND THE EMERGENCY BRAKE SYS PRESSURE SWITCH AT FAULT.  REMOVED AND REPLACED THE PRESSURE SWITCH IAW AMM 32-44-07.  OPS CHECKED GOOD.
