Check the harness for corrosion. Normally(the corrosion that is) would be a greenish color. Check inside the bulb insert also.

That is a dual filament bulb you're using right? Did you have someone test the sockets when you apply the brake? Did you check the connection at the brake switch? There aren't too many things that can be wrong. It's either the switch, bulbs, sockets or wiring. Start eliminating things.
