Sounds like a very odd problem, but if u have had any replacement brake light bulbs lately I would check and make sure they were installed properly. I have seen improperly installed bulbs do weird things.

With the lights, radio, turn off when you press on the brakes, first check by the brake light switch to see if there is any place the wire is pressing against another wire. If it was a short then the radio would still work as the brakelights. To me it sounds like a looses wire, somewhere by the brake pedal switch
