see if power goes to the brake switch, and power comes out of it when brake is depressed. If not, fix that. If power goes out, then there's a short going from the switch to the bulbs. Many guys will just run a new wire from switch under the car to the brake lights, as the rest involves computer modules which you would then bypass making it simpler
