Well, I think I found the problem. I took photos.
First, a photo of the rear right disk from the outside. Weirdly it shows some pitting which I've never seen before. I then took off the pads. Note the MASSIVE scoring on the inside pad. WTF? did a rock get stuck inside?! I held the pad against the inside of the disk and you can see that past the scoring, the disk wasn't even making contact with the pad and a decent section is untouched and rusted.
Then to the rear left. Disk looked a LOT better with hardly any of that scoring showing. Pads look a lot better as well, but again, there is a weird groove on the inside pad. A photo of the disk from the inside shows it looking awfully rusty considering it seems to have very little wear.
In both cases calipers look good and glide easily.
Oh, and the front brakes are excellent. For reference I took a picture of the outside and inside of the front right corner.
Finally a photo confirming the previous owner installed Hawk pads.
