Expensive brake job?

Unless you've done a ridiculous amount of mileage and worn rotors below spec a disc machine and new pads should have been like new

If you're taking about a brake lathe, forget it. Unless you have a lathe that works on the car, most of the ones out there have a runout way out of spec for what the rotors actually call for. (I think the worst one I've seen was .010", when the rotor runout spec was something like .002".)
