Try this first. This is going to be a process of a limination
1. Disconnect the connector from the brake light switch use a small jumper wire put in a new fuse and bulbs if needed jumper the connector if it blows the fuse that right there tells you switch is not bad.
2. Next go to rear of car find which side wires run down which side of car. Follow the wires and look for another connector unplug it and make sure there is no corrsion in the plug. Also check the wire in the trunk real careful we all know things get thrown in there jacks and such and that can nick a wire. What you got is power going to a ground. Once you have checked these things. Leave the plug disconnected jumper the plug under the dash again with new fuse of course if it blows again then you know for sure it is not in the lights in the back.
3. Ok now you have it narrowed down. Thoes wires usualy run down along the side of the carpet pull the cill plates usualy #2 phillps head screw driver unless torx. Check thoes wires real good. One of thoes screws may have chaffed the wire going from the brake light switch back and when you step on the brake it is sending the power to ground blowing the fuse. Hopes this helps better than going to a shop when you can check it yourself. (NOS) 8)
