Bill,

Sorry... I was thinking about doing more than one corner. Your approach would be fine if you are doing just one corner.

With calipers still mounted (but pads removed) you could put thin pieces of wood between piston and rotor (on all of the calipers) and push all of the pistons part way out at the same time. A nice time saver.

To my way of thinking if one caliper is bad then they all probably need attention and the incremental effort to rebuild 'em all is small compared to having to jack the car up a few weeks later. You gotta take all four wheels off to bleed, anyway, so why not do all the calipers at one time?
