1993 Hyundai Elantra. Just recently I discovered that my brake lights will not turn off. When I lift the brake (from underneath) just a little, the lights will turn off. But, when the brake is left in the normal resting position, the lights stay on. Is it possible that the spring that pulls that the brake up while not in use is worn out and that there is not enough tension to pull it high enough to where the lights won't turn on? If so, do I need to order that part from my dealer?
