That is truly a lot of work everytime you want to adjust. The mod involves removing the caliper once and grinding half the stop tab off(directions were on here somewhere). The rest of the adjustment is easy by loosing the lock nut,turning the piston stud until it touches the disc,then back off the piston stud a little,now put the arm back on as far back as you can get it as to get the most travel out of it,tighten down nut. Pull e brake lever. If lots of play yet, loosen lock nut and turn piston stud to take up the slack ,tighten lock nut. All without removing the caliper. The only time you need to remove the caliper is to put pads on it.
