Sudden Acceleration. -I was driving on a highway. I accelerated to pass a truck and when I took my foot off the accelerator the car continued to gain acceleration. The gas pedal had returned to a normal position but the car was still accelerating. I had to put full force on the brakes to get the car to stop. One of my passengers noted that there were flames around one of the brakes. I turned the car off and we waited approximately 45 minutes for the brakes to cool enough to proceed without further incident.
