The brake lights won't turn off
If your rear brake lights are on all the time, I would first check your brake pedal. Near the top of the pedal, probably just about where the pedal is attached to its pivot, you'll see a little switch that is either pressed in or released when you step on the brakes. That's the switch that controls your rear brake lights. As an experiment, have a helper look at the brake lights while you manually pull or push this switch all the way in and out. These switches wear over time and can stick in position. Fortunately, they're not expensive to replace, if that turns out to be the problem.
If your brake light switch seems to be working properly (hard to tell if the brake lights won't go off), a second possibility is that there's a short somewhere in your wiring and your brake lights are getting power from the shorted wire. I think this is a pretty unlikely cause, because most of the wires that rub up against the brake light wiring are for your turn signals and tail lights, and these are not normally energized. If you said that your brake lights always came on when you activated your turn signal or when you turned on your other lights, then this cause would be much more likely.
Check your brake pedal switch and the wire connections to it. I have a feeling that you'll find your problem.
