A year later, when I went to replace the pads, the caliper was once again stuck. I ended up replacing the caliper anyway.
But Brian Carleton is right. If there is any corrosion whatsoever, the caliper is not rebuildable. And I believe that corrosion is mostly why they fail. So what's the point of rebuilding?

The MacParts rebuilders rebuild Calipers with big pits in the bores; I have seen them.
One of the reasons a lot of Members have complained about rebuilt Calipers leaking.
I rebuilt the Calipers on Mine years ago and there was some pitting inside. I have had no issues with them.
In Fact I have rebuilt the Calipers of all of the Various Vehicles I have owned and they all had some pitting in side.
Now if the Piston is pitted you either get a new Piston or replace the Caliper.
I think the Car Owner is actually more likely to do a better Job rebuilding the Calipers than the MacParts rebuilders.
Where I have had issues rebuilding Calipers it has been with the Caliper Kits. Dust Boots that fit poorly don't don't want to stay on the Caliper.
