I tried to take my own advice on this one and the first attempt failed. I could not punch the required size hole in the feeler gauges I had, not wide enough so they broke each time I tried. I measured the end play in the caliper bracket at .005". I learned a aluminum beverage can is .004" thick, what's .001" between friends? Punched out a washer to shim it and reassembled. Should be more better!
