Narrative:

On approach the flying pilot asked for gear down. Upon selecting gear lever down an EICAS message displayed on the center display indicating lh and rh brake fault. I as the non flying pilot and captain discussed quickly with the flying pilot; the first officer; that we should do a go around and run the appropriate QRH checklist. We did the go around and selected the gear lever back up and the EICAS message remained illuminated. I ran the appropriate QRH checklist and looked at the appropriate page in the QRH in order to get the new landing distance. Even though it did show we could still land in ZZZ with the runway length at ZZZ I elected to go to ZZZ2; which has a much longer runway as a precaution. We also did not have but 4800 lbs of fuel at this time and did not have much time to stay in the air. I notified ZZZ ops and the dispatcher through company indicating we were going to ZZZ2 and to please notify them of our arrival. Upon landing the fire trucks were waiting; again as a precaution but no emergency was declared and they did not follow the aircraft to the gate. The brakes did work properly and the lights did go out approx. 7 to 8 seconds after gear was selected down for the second time. When talking to dispatch and maintenance control; maintenance control wanted us to ferry the aircraft back to ZZZ without a logbook write up since now everything was working. I felt that was not the proper thing to do since I diverted to ZZZ2 and with no logbook right up I had no reason to divert. The dispatcher agreed with me and since I told ZZZ ops in the air that we were diverting they had dispatched two mechanics from ZZZ to look at the aircraft. They did the appropriate checks when they arrived and indicated that it was only a computer indication and yes the brakes work properly. We were then re dispatched and we ferried the airplane to ZZZ with no other incidents.
