Brake Rotor Resurfacing
I've had this happened to me twice, so I was just wondering what other people do. When I replaced the pads, I measured the rotor, and thickness was still above the minimum. However, when I took it to the store (Pepboys) to get resurfaced, they wouldn't do it because it wasn't "thick enough".
I didn't have time to go around to see which shop would do it, but what would you do if nobody would turn your rotor even though it's still within spec? Is there a limit where it's thick enough to use, but no enough to be resurfaced? Mine didn't have any abnormal or uneven wear, just wanted it to be perfectly flat.

IIRC, there is only 2 mm between "new" and minimum
Turning them might remove enough material to put them below minimum
Most people replace the rotors and do not get them turned

Amazon and Ebay, but you wont get them today
Hopefully you have a Motive power bleeder. It makes bleeding super easy

That and they'd rather sell you new rotors.

Another question is do you know where to get those troublesome screws (for Porsche and Honda) that hold the disk? I seem to strip then have to drill and break them every time I change rotors.

That's fast. Thanks! But do you happen to know anywhere else (I mean locally)?  because I usually order from RockAuto and Amazon.

ECS Tuning has them as well.
But shipping might be expensive for 12 screws...

If the rotors are not warped, in other words, no vibration when you brake, then just re-use them until they reach the wear limit.
Even if they have nasty gouges, as long as they don't vibrate, you are good.

Your local Porsche dealer
If you are in the San Diego area, try TC's Garage. Tom may have them
Maybe your local Indy, they might sell you a few
IIRC, you can do without them as the rotor will align on the hub (?) and the wheel will keep it in place
I could be wrong on that YMMV

Yup. I just slapped a set of EBC red on mine a few years ago, next time it gets new rotor and pads. I didn't even use the anti-squeal pads and they've been as quiet and strong as ever.

Correct, the only function of the screws are to hold the rotor in place before the wheel is installed (especially before the caliper is installed). I have run my cars without the screws on occasion and lived to tell the tale! Once the wheel is installed, the lug bolts firmly secure the rotor to the hub.
