Narrative:

While taking off; after pushing the thrust levers forward; we received an EICAS message that said the parking brake was set. Realizing that it was impossible for it to be set; because we were accelerating rapidly; we continued the takeoff roll. Once airborne the message cleared from the EICAS. Approximately twenty minutes into the flight; the EICAS message reappeared. We called maintenance control and they informed us that it was most likely an erroneous message. Not feeling confident that the brake was not set we decided to divert to an airport that had longer and wider runways. After discussing it with dispatch; we decided that kpit was a good diversion airport. We continued on to kpit; declared an emergency with ATC; and landed uneventfully. In the future I will call for a rejected takeoff. This way we can better think about the situation and decide if we should continue or cancel the flight.
