when you pull the hub off take a picture of the brakes so you can see all the parts, so you can tell where everthing goes back together.

I had the same problem! I used a piece of wood to keep the break pedal depressed and then started to remove one of the break lamps and to my surprise it came on! Same thing on the other side. So I did not seat (bottom out) the lamps in their sockets and both break light are now working properly. I had a similar issue last spring but that time only one light was out. I put in a new bulb and it still did not work so I messed around with it a little more and it started working. Never did figure it out until now. Hope this helps!
