Ok instead of bumping up another brake pad thread, that i did search for a read and couldnt find my answer. I have a quick question, at what point would you change pads going by mm thickness of the pad? I read on the COG forum that stock pads are 3.8mm the thinnest pad i have is 2.2mm. how thin would you go in millimeters before you changed? FYI i have Gallfer gold HH pads with about 13k(ish) miles on them. Those measurements are the pad material only not including the backing.
