Press the switch by hand to see if it's stuck. If it is, pressing it may force the stuck part. Find the fuse for the brake light and pull it out. Remember to put it back in before driving again Find the brake lightbulbs and remove them. Remember to put them back in before driving again. Disconnect the negative battery cable.
