I have a 1997 Hyundai Tiburon, and tonight I stopped at a 4 way stop. When I went to turn, the car wouldnt go and the brake was stuck in the up position. I stepped on the gas again, and it still wouldn't go. Eventually I was able to slowly roll off to the side of the road. I restarted the car, it still didn't go but the brake was no longer locked. I restarted it once again, and my car finally went and I got home (like a block away) fine, even with more stops and everything. What could be wrong?
