I put on track wheels today and took a look at the brake pads. It appears the outboard pad was in good shape and the inboard pad was nearly worn out. Pads are stock GM for an 08 with Z51 package, about one year old.
Obviously not . With the pistons inboard, that's indeed the cause. And even when they slide freely, there's usually a bit more wear on the piston side with asymmetric calipers. You need to clean and lube them every 'X' thousands of miles, especially if you use the car in the rain. Good luck.
shake down that wheel , you either have a bad wheel bearing and it is pushing the pad or the slides on the caliper are sticking due to rust, dirt ..............
Okay boys, I took a long look today. Inboard pad worn on all four wheels. Pretty much worn out on the fronts. Outboard pads near new. Calipers move easily with light hand pressure. Obvously something is wrong. Brake fluid a little over full. No sign of hub or bearing play.
Car is pretty much a daily driver with regular autocross days.

TRACK? What kind of track?
Heavy track use is death to the whole braking system unless maintained correctly. Which most of us know. But that still doesn't explain uneven wear. If it was just one I'd say the caliper was sticking, but all 4? That's above my mechanical skills....hopefully some one experienced in that category can help. Good Luck!
I'm guessing that the calipers are not floating when hot. Don't know a fix.
I haven't had them seize up from heat even when tracking but certainly not for autox. But, I have to guess it is an issue with them not floating. I would disassemble the caliper pins and clean and re-lube them while checking for galling. Swap the inner pads to the outside and see what happens. I usually rotate my pads to cancel out any taper they may receive every now and then.
