I replaced my front pads in Gainesville, FL, while I as on the Epic Ride. I had 71,457 miles on them and the left pads were less worn than the right, IIRC. I replaced them with EBC's organic pads and they're still in decent shape after 43,000 miles. I am trying to be more intentional about using the rear brake some of the time. Because of my 3 right knee replacements, I don't have quite as much ankle flexibility as I used to, and I had developed a habit of almost never using the rear brake. I'm working on that, since I can tell that using the both brakes settles the suspension when cornering and shortens my stopping distance in a hard stop. Still, I kind of doubt I'll live long enough to wear out the rear brake pads.
