- Ideally you should turn the drums/rotors every time you put new pads/shoes on. It's cheap, I'd do it.

That's a waste. Don't turn your rotors unless it's necessary. There's only a limited amount of times you can do it.

Of course, if you have a modern car you will probably need to replace the rotors before you change your brake linings twice, due to the fact that modern rotors suck.
