i was dropping my girl at work, when i was driving back i noticed that the light was red so i down shifted from 4th to third, and as i was slowing down i put it in neutral then the light quickly changed green, i was going at a not so fast speed(like 2nd gear speed) and i notice someone behind me was coming very fast so i put it in 3rd and noticed that the car was dragging didnt want to go fast then i put it in 2nd and drove to the nissan dealer to pick up parts, when i came out of the car i noticed the smell, then on the way home i saw smoke from the passenger side like near the tire, i quickly went to my job and checked the brakes but they were fine. i quickly got the other car out and parked it.
