The adjustment is we’re the peddle attaches to the arm . but if there is too mush play in the bushings then when you push on the peddle it moves and it may be to much play you can try loosening the bolt and move the peddle to centre it in the hole.or were it won’t rub when you push on the peddle.one other thing that may make a difference is the condition of the cab mounts.
