I think it is my outside pad that is consistently the worn one but I really would have to look now. The caliper has to be removed during rear wheel removal and I know the shop folks well. I tell them to look, if one is more than 2/3 worn, just change it when a tire is put on as I know it won't last until the next tire change. It is an easy job but since I don't have an indoor place to do this, it just works to let them do it while they have the caliper in their hands.
As for the wear. I am just scratching some numbers on paper here for the idea. I got the bike at 7800 miles a little over 4 yrs ago. I noticed the rear rotor wearing and discussed it when doing tires. Once the ridge on the outside of the rotor was about the thickness of a worn penny I swapped for another one. A penny new is 1.55 mm thick. Figure a worn one is a little below 1.5 mm then. It seemed worn about the same on the inside If I can put a penny flush in the worn area then with each side it has worn about 3 mm. When I changed the rear rotor the bike was at 98,000 miles so that makes it about 33,000 miles / mm of wear. Yes I agree the rotor was a bit thin. Still the bulk of the stopping is done by the front. The rear had a minor pulse to it that had first been noticed around 15,000 miles and had remained the same. It was only detected when the bike was barely rolling traffic going about about walking speed (like down hill in very slow traffic). I most likely will change the rotor again this time when a worn dime can almost fit in that space.
Is there foolishness here with this?
