We were cleared for takeoff. We ran the Before Takeoff Checklist and taxied into position for takeoff. As I advanced the thrust levers to takeoff thrust; we got the aural warning 'TAKEOFF BRAKE' and the associated EICAS warning message. I aborted the takeoff at very low speed; contacted the Tower Controller and advised them of the abort. We taxied off of the Runway at B4; made the turn onto B; stopped the airplane on B and ran the Aborted Takeoff Checklist. After we had finished the checklist(s); we verified that the brake had indeed been released and that there was no indication of the brake being on. We also noted that we had pressed the TAKEOFF CONFIGURATION button just prior to takeoff; and that we had heard the 'TAKEOFF OK' aural message. The Captain then called Maintenance. The Captain filled out the logbook; and reset the brake system in accordance with Maintenance guidance. Once we had complied with maintenance procedures; Maintenance cleared the airplane and we got ready for another takeoff. We re-ran the Taxi Checklist and the Before Takeoff Checklist. We then completed a successful takeoff and proceeded to destination. There was no indication of the brake system being engaged prior to thrust lever advancement. I think we responded appropriately and effectively to the situation.
EMB145 First Officer reports a takeoff warning when power is advanced for takeoff and the takeoff is immediately rejected. The Takeoff Configuration Test button had been pushed prior to taking the runway with Takeoff OK enunciated. Nothing can be found out of position and the second attempt is successful.
