Brake Job Scare

I've only had the Merc for a little over a year now and haven't had anything go wrong yet, but when/if it happens I expect MB to do the right thing. My benchmark is Audi based on two separate events 15-odd years apart. Back in the early '90s my father's Audi 4000 transmission took a dump out of warranty. He had it rebuilt at an independent shop and as an after-thought send a letter to Audi telling them about it. Out of the blue a check arrived soon after for $1,500 usd.
Fast forward to Christmas this last year and my wife's TT, an '04 15k miles out of warranty, had a coil pack decide to catch fire 30 miles short of a 7 hour drive across the middle of nowhere between Phoenix and southern California. The car gets towed in to the dealer only to wait for a week for a new $15 usd connector. The good part was Audi sending us a check for the cost of the tow and the dealer repair, plus paying to have the other five coils replaced.
Maybe it's just me?

A problem has emerged.
I took off the tire only to see that the brakes did not match.
I bought them from MercedesGenuineParts.com

I noticed the Hex bolt was loose. I don't know how in the world this has happened.

Did some idiots try to mess with my car? It was only the top ones. Maybe they tried to steal them? Who knows.

My original Brakes have these holes where these pins go though them. Not the ones I got.


My only conclusion would be that I got the Luxury ones and not the Sport ones

But on their site they dont have a place to specify Sport so does this mean I should get the C230 ones?

Here is the one I got. Hopefully I can ship it back to them and they can get me the correct ones without a hassle.
I got a couple of questions:
Why would my brakes squeak? It seems like there is enough pad on there doesn't it?
Thanks guys
