well here in alabama when i leave in the morning its in the 20's but i warm my car up for a few mins then i take the parking break off and back down the driveway. today i figured out why my parking break was on when i got to school. when i back out the driveway i heard this clicking noise and the parking break handel just happened to catch my eye. it was aobut half way up?? so i put it back down and then start driving down the road watching my parking break handel and all of a sudden about 10 feet from my driveway the handel start clicking and it rose up about half way and stoped. then i put it back down and everything was fine. and the parking break only holds on the very top click and if i close the door hard or move fast the car will start rolling im my driveway which hardly has a slope at all. whats going on?
