I always just buy rebuilt, as I am not willing to risk my safety for a few bucks. But I have seen experts rebuild them. They clean everything several times as Norsky said, and lubricate everything with brake fluid to help assembly. To get the seals in, they use a feeler gauge slipped between the seal and cylinder.

Watch out for the small o-rings that go between the caliper halves. You'd be surprised at how many don't see/notice those little turds! Clean them well, hone if needed. While ya got them apart, take the bleeders out, and run a wire down thru the hole to make sure it is clean, all the way thru the caliper(it'll make sense once you see it). If the caliper bores are corroded, don't even bother with trying to rebuild...it won't work. The pistons, if corroded can be replaced, but the bores can't be honed if they are corroded....

All I need is time and money! Getting there!
I have rebuilt many calipers of many types. But it's often found that there is enough corrosion that it cannot be done. But hey, it often works.
You will need to consider using the original type seals, or go to the o-ring seal. The o ring will tend to hold better when the car sits for a long time, like winter storage. The original seal will hold a bit better is severe braking. The extra pressure actually makes it seal tighter, but only when applied.
Or you can go to Autozone and buy stainless lined rebuilt with a lifetime warranty for about 60 bucks per caliper. That is whats on my car.
