Brake pedal trouble with Xbox 360 Racing Wheel

I have bought a used Microsoft Xbox Racing Wheel and have recently started playing. I have noticed that every time I let go of the gas pedal completely, the braking lights turn on. And when the car eventually stops, it starts backing up in reverse at full speed.

Has anyone else experienced this? It happens on any game. I also switched pedal sets as I have 2 sets.

I had this problem with mine, and it turned out that I needed to change out my batteries. There is a compartment on the steering wheel portion of the setup that opens up when you push a grey button, and that's where the batteries go. I want to say that it's all the way over on the right side of the assembly, but I am not 100% sure, as I do not have it in front of me. It's pretty easy to find, once you know it's up there, though. If you can, use the kind of batteries meant for digital cameras, etc; the wheel draws a bit more juice than a normal XB360 controller.
