I would like to share with you what happened to my MB S63 AMG 4-Matic 15'. The car is 112,000 km away and has never been driven on a track. I enclose photos of the condition of the disks. This happened while driving in the city. Do you have any idea what is the cause of this type of damage?
This is my second MB S63 AMG. My previous one was MB S63 AMG RWD 11' with the V8 5.5L. She has no problems of this nature, perhaps due to the lack of a Carbon Ceramic Brakes.
After what happened, I won't buy another MB S63 AMG for sure.
I have a 2016 S63 4matic with the ceramic brakes. Have had no issues, other than the occasional brake squeak when cold. I have installed updated pads front and rear. I would think road debris, however I still dont see how that could happen. Unless this happened when you were parked somewhere and someone physically damaged your car while you were away. I have never seen that happening before, ever. I do drive my vehicle pretty aggressively. Basically like I stole it. Lol.
I have had the same issue on two rotors on our E63s (which uses the identical rotors - as virtually all AMG's do). Lower mileage but Mercedes covered the replacement for free as it was considered a manufacturing issue (delamination), not usage. Getting Mercedes to replace it on their coin will be difficult with your mileage, given that rotors are considered a consumable product but it is worth a try.
A rock chip as a cause is more or less impossible, given the location/angle.
A replacement with labor will run $4500 per rotor at the dealer. Less via Ebay, etc.
Also, you might want to put the car on a lift; our second rotor had the damage on the inside...
Hi, today after short trip from central London (19 miles) my right front disk got delaminated damaged 😡
Car with 30102 miles on the clock, never used acid to wash the wheels.
Went straight to my local MB Service at Heathrow, will leave the car on Friday for inspection.
Hope this will be replaced under a manufacturing issue.
This is a rare issue to be sure. I for one would take CCB’s on any car for the brake dust alone.
The poster from the UK has a chance to get them covered because it is a manufacturing flaw, not usage.
After Friday Mercedes service visit, the case was send to head office of Mercedes-Benz
I did make additional photos of the damaged rotor.
Greetings all,
Yesterday morning got a call from Mercedes Benz Heathrow, informing they have full set ready to install on my S63, under manufacturer warranty 🤩
Went today to take a look, as I did not believe Mercedes Technical Department would do this after 10 months of waiting 🥺
Part number A2224211400 / A 222 421 14 00
Just want to say thank you Mercedes, the best or nothing 🥳

The wait was certainly worth it and I am glad it worked out for you, thanks for your update. Now enjoy your car : )
I had the same issue with my 15’ S63 Coupe. Replaced under warranty as a manufacturing issue. It happened when I did hard breaking from about 120mph down to 60mph. Didn’t hear or feel anything, but saw it when I came home.

How may miles did you had when this happened? It looks exactly like my issue...
My car is back on the road with brand new CCD, paperwork in attachment. There was a delay with one part missing, 1 week additional waiting to ship this from Germany and 3 weeks as my Instrument Cluster died.
Replacement parts as follows:
A2319057300 wear sensor (140 on diagram)
A2204210171 disk bolt (210 on diagram)
A0199907901 bolt w flange (70 on diagram)
A0004206900 brake pads
A0014211991 metal spring plate for pads (80 on diagram)
A2224211300 left disk
A2224211400 right disk
The old pads were used in about 60-70%, so the time to change them was close anyway.
In addition to service, my instrument cluster give up/died just before Christmas and day before the car supposed to go for service, so I was forced to upgrade to new IC motherboard with Supersport Design theme, it looks fantastic.
Bought as well new DoIP interface for OBD2, so now learning to code and I have manage to activate few new options, like RACE mode, seatbelt warning ON, alarm siren with horn and dynamic data with telemetry display.
Before it actually happened I was seeing some surface issues on my rotors. Look below. These are signs that show you have a problem.
Amazing, I can see it's starting the delamination, I did not have it so much on my old disks.
One more thing I noticed when they removed left disk and pads, the pads had longitudinal taper wear (i.e. greater nearer to the leading edge, and lesser nearer to the trailing edge).
So the pads looked almost like this:
Apparently this is a normal wear with multiple piston calipers and sometimes after a track day 🤷
Will it be possible as a solution to get more even wear out of the pads, to occasionally flip the pads in the calipers from inner to outer, so that the edges that were leading last time are now trailing, and vice versa?
Doing so occasionally also gives a chance to inspect the pads and make sure they aren’t getting too thin 😁👍🏻
