a link on the step by step procedure (with tricks to do or things to avoid) to rebuild brake calipers?

looking in my workshop today i took stock of some of the stuff i have lying around in cartons.

there are at least half a dozen pairs of rear and nearly that for front brake calipers in various states of non use from clean to rusty and nasty...almost all for 240's. many i just get from the boneyard when i am looking for stuff and figure i will use them eventually....so i have no idea what internal state they are in having never driven them.

eventually has arrived so i am now going to teach myself how to rebuild these things.........unless some of you can persuade with good reason y i should not.

i have the time, motivation, do not need any of them for current cars repairs so i can take the time to do it right. i have a clean tank and a most everything i would need to do a proper job except the actual knowledge of having done it before.

so,

tips, tricks, links, books etc will be most welcome!
