Default Damaged brake caliper

I pulled my car into the garage yesterday and as I locked the doors I noticed that the rear brake caliper wasn't looking right. I checked the other three calipers and the opposite rear was in the same condition. I had been driving a little aggressively on some curvy back roads and really hitting the throttle, though I don't think that should have damaged them.

A couple of questions come to mind:
  • Any thoughts on what may have caused the damage?
  • Is this a material defect?
  • Will it be covered by the Audi warranty?

There's normally a whole other piece of metal that has the "S5" moniker on it.

I'm hoping that someone with knowledge of breaks can tell me if the rear brakes are damaged to the point of not working...

I might be missing something here, but that looks just like my rear brake setup and they work fine. Mine have never had th S emblem on the rears.

Here's a poor partial image of my front brake caliper showing a nipple and part of the moniker. If I find the time today I'll pull the wheel off and get a better picture.

The fronts are different than the backs.

I think that slot or opening is for cooling of the pad!

Early production 2018's had the S logo on the rears as well, but that changed sometime last year. Same on the S4's. Your pictures are normal for current production.

I went out and popped the tires off to get a better look. (Just what I wanted to do on a sub-freezing Sunday morning!).

Here's two photos of the back brake:




Compared to the front brake:


And, here's a little extra surprise I found on the garage floor after the wheels were back on! What does the "FE" stand for? "Freakin Extra" lol. So now I also have a wheel that's out of balance.
