Yeah, haha, but as in a lot of these threads, nobody posts their solution. So, I'll restate the problem.

2004 Disco II. Brake light is on continuously. Checked reservoir, it's full. Unplugged reservoir cap connector with ignition on, and light stays on. Disconnected parking brake switch and light stays on. Rear brake lights all work normal. Any help is appreciated.
