In the same school as Beelzebubba, when I have a rotor turned, go to a good machine shop and tell them precisely how many mils I want taken off each side, some of these guys don't even look at the micro gauge and just take off an eighth of an inch.
Rotors of drums have a minimum thickness and the TIR should be checked, but sure not talking about the drums or rotors on the Cruze, talking about drums or rotors that cost a couple of hundred bucks each to replace. Ha, standing there watching him with my own micrometer or caliper in my hand.
Major enemy around here is road salt, the vent holes are plugged up with rust, some can be cleaned up by soaking in hydrochloride acid in a 50-50 mix. Others are too far gone, never know what I am going to do until I check the thickness and TIR. Also prices, like in a tiny rotor or drum in a car like the Cruze, may only cost 5-7 bucks more for new ones than pay to have the old ones turned.
Certainly don't do this by the clock, depends on the condition of the old one.
A certain amount of truth to what jblackburn said.
Major problem I am finding my my 2012 2LT is the terrible job they did plating these pad brackets, and the clips that create a dead area where road salt builds up rust. Clips are a very stupid idea, when rust builds up, jams the pads and can wreck your rotors in a hurry. A set of four will run 120 bucks, but unless I see them and test them, can be just as bad as what I got stuck with. Tees me off.

Based on my experience with our 04 Cavalier, after 50K the rotors on this car were shot, replaced them with a good quality aftermarket rotor, and still in good condition after 130K miles on this thing, just replaced the pads.Also I wouldn't turn them. Buy some high quality replacement rotors - the GM ones are junk.
