There are a few sources you can use outside of the forum for repairs.
1) a factory service manual.
2) a chilton or haynes repair manual.
I usually get my auto parts from autozone. Some swear by them, and others curse them. Me personally have had only one problem with a clutch master cylinder that was fixed. I always went there for the military discount.
In the forum I'm not sure there is a how-to for wheel cylinders. A good tip is to do them one at a time so if you screw one up you can look at the other to see how it is supposed to go. Lug studs are pressed in. The old one will need to be driven out with a punch or chisel and a hammer and the new one pressed, pounded, or pulled in.
