I haven't looked at mine closely, but I would imagine that the dead pedal is a bump-up molded into the floor. You could probably eliminate some of the bump-up by removing the carpet underneath it, and/or hammering the floor with a sledge hammer. Otherwise, you should probably try an adjustment to your seating position.
