I have just been trying to make sense out of the measurements listed in my 09' Service Manual and something doesn't jive. Yesterday I went to Cascade Harley and measured the actual thickness of the front and rear new pads. Both measured 3mm. 3mm = 0.12". I think Harley got their cm and mm confused when they printed the manual or else they really mean that you can take the pads to the metal - almost. Me - I'm going to replace the pads at their half life = 1.5mm or 0.6" Anyone have the "real" answer?
