I've looked at both the Avid and Park Tool instructions. Everything makes perfect sense except the adjustment for pad wear. The instructions say to set up the gap to be 2X on the inner (fixed) pad. Once the pads have worn the Park Tool instructions direct the reader to turn the inner adjustment knob 2 clicks for every click on the outer. If the inner and outer pads wear equally I would expect an equal number of clicks on the two knobs to restore the original pad gaps. Am I missing something?
