I disagree, and apparently likewise does Mike Miller, that there is a
significant problem removing the UFO rotor from the hub and
serviceable caliper. Just tilting the caliper off the hub will force
sufficient piston retraction and move the caliper outward enough such
that the outer pad will clear the rotor’s inner ridge as one wiggles
the rotor off th hub and upward. At 225K on my UFOs, I have nice
annular ring ridges either side of the rotor’s active surface, which
make for great passive wear sensors!
