Do your front disc brakes, for lack of a better description, get loose as you ride? Mine start dragging and sometimes when I apply the brakes the front one makes a thump/clunk and feels like it moves enough to slightly pull the fork to the left. After that its good for a while but happens again later on in the ride. If its bumpy it happens more often.
