This is more than likely due to a fault in the module that controls the brake lights in your vehicle. I believe this is a relatively common problem, but you'll need the help of someone who knows how to work with those modules and has the tools.

If you mean the brake lights at the back of the car stay on it is probably a defective brake light switch. If a brake warning light comes on and stays on on the dash while the car is driven it may be caused by a low brake fluid level. Any displayed brake problem on the dash may effect or bring on a traction control or ABS malfunction light as well.

Lift up on the brake device while releasing it. The spring is weak.

the sensor under the dash may either be loose or not working. I just fixed mine, and all it was was a loose nut that holds the sensor in position. All you need is a couple wrenches and you can get it lined back up to the little round plastic piece (you'll know when you get under there and see it) If it is lined up then your sensor could be no good/stuck. All the part really is, is a little module with a button that sticks out, When depressed, the lights are off, when you apply the brake it is fully extended. hope this helps
