It should be your brake light switch. There is a little plate welded to the arm of the pedal that has a hole with a rubber stopper. The rubber stopper is most likely missing, or damaged. You should be able to take a flashlight and see the plate and the switch. If the hole is plugged up, you will need the brake light switch, if not, replace the plug.

if you follow your brake pedal up youll see usally a white colored plastic a plunger type switch it looks like a threaded rod thread it until the brake lights go off ,youre trying to push the plunger in,turn it just untill the lights go off,if it does it again its probally skipping on the threads and youll have to replace it
