Rotors are cheap. $50 for Brembo or Myle.
I measure runout. I measure thickness. I measure thickness variation.
I look at scoring. I look up the specs when I need them.

In practice, it's pretty simple:
1. Replace the OEM Jurid/Textar pads with $35 Axxis/PBR FF equivalents.
2. Measure the thickness of the existing rotor
3. If it's too thin, replace with Meyle/Brembo for $50/wheel

I don't blame any shop for replacing *everything* they can.
The more they replace, the more they make and the less people come back.

That's just logic.
