Replaced rear rotors, calipers, pads, hardware. One wheel was making noise as I test drove it. I found the rotor had some scratches closer to the inside but other than the pad I couldn't find what might be scraping it.
So, I moved the rotor and pads to the other wheel. The sound moved as well. Then I swapped rotors again and the noise moved. I put in the old rotor and no noise. So it is definitely something up with the rotor. I am currently concluding that the rotor is defective, but wanted to know if anyone had any other theories or anything else I can check.
