I'm sure this topic has been discussed an various fashions throughout many threads, but I haven't found anything specific for the E63. I am about to lock in order and was still on the fence regarding the CCBs. I understand, or believe to understand, that they improve handling due to less unsprung weight, create very little brake dust (love that idea), don't really improve braking distances, no fade when tracking (I'll probably track the car once a year), not as effective in cooler temperatures. I've had a F8X BMW M4 with them and did enjoy the look. I had an F90 BMW M5 without them and didn't really think about not having them, except when the brake dust would build up. If I trade the car in 2-3 years, I noticed used cars in that range have very little value add from the CCBs. So basically the new owner eats almost all the cost of them. So some questions from those with this car and has had experience with both brakes:
1. Has anyone really noticed handling differences due to the unsprung weight? It seems that the little weight savings would not be noticeable.
2. I have heard these CCBs are noisy and squeal. Is that true? How does it compare to any noise from the steel brakes?
3. Finally, I am going with the obsidian black and night package. I would think these rotors look a little darker than the steel ones. Do they look dark enough to notice the difference in giving the car that blacked out look compared the the high shine of the steel brakes?
4. Any other thoughts you want to throw in.
I have had them on two Porsche 911's and now on my 4 day old E63S. I have never had any brake noise from any of them. Maybe I am just lucky but they have been silent. No brake dust and looks is the main factor for me. Unsprung weight is just a plus which I do not feel in my E63S because I did not drive a steel brake version. I hate brake dust to the point I don't mind spending a few extra bucks. The rotors are a bit darker than the steel.

1.) I'm not driving on track, but yes the physics dictate that handling will be a bit better
2.) No noise for me, even in winter and cold starts.
3.) Rotors are not the noticeable distinction, but the calipers obviously are
4.) For me, these brakes are simply amazing. I had steal on my '14 AMG and was never disappointed, but the dust was a regular thing and the CCB are just dialed-in better and far grippier it seems.
Well I have steel rotors on my 2021 E63 and CCBs on my GTC - you won't notice much of a difference with regular driving. Steel in my experience is more prone to noise. I have had several sets of CCBs and they are just superior in every way unless you are the one replacing them. Brake dust is practically non-existent and if I had been able to find the E class with them I would have paid the premium. I agree that CCBs don't increase the value of the resale of a car, but if there were two cars the same and one has CBBs I know which one Im buying...
Fun fact, all current version Mercedes CCBs have the same parts across the fleet. They interchange from the GT, S, E and at least the fronts for the C too.
I've never driven an E63s with steel brakes so can't compare.
No brake noise. The steel brakes on my other vehicles make more noise.
No brake dust.
Have never had appreciable brake fade. Haven't tracked the car yet but have done some spirited mountain driving where down hill runs give them a good workout.
Great initial cold bite. Doesn't get too cold in San Diego, but I drove the car in Germany for two weeks in some sub freezing temps and they were still great. If the steel brakes are any better when cold, they must be insane.
At the Laguna Seca AMG Academy they use the E63s with CCBs for the braking exercise. The cars get max panic stop braking repeatedly from 40 to 60 mph to zero and aren't bothered by it at all.
Only about 1K in with ownership (bought a few months ago), but no brake dust, "look" is fine, function is phenomenal. Cost for replacement is likely astronomical, but not looking that far ahead or back, and elated with the choice to buy an E63S with them optioned. No dust, no noise, no regrets.
I have heard that the CCB are noisy in cold, wet climates (which is where I live) . One dealership I spoke with aggressively suggested NOT to get CCB. They claimed that almost every car they sell with CCB comes back in the winter with the owners complaining about squeaking.
2018 CCB owner here. No noise at 22k miles. Winter, summer, whenever, no noise...and if you were to get a squeak the remedy is just finding an empty road and doing 3 panic stops from 60mph. The only reason I've ever had to wash the rims in 3 years was just dirt, rarely do they ever need to be touched at a wash, no brake dust. The rotors last twice as long as the steels, so over 100k miles...but I'm pretty sure a full brake job on CCB Mercs is about $12k right now, but I will have moved on to something else by then.
My ‘18 E63 wagon with CCBs is awesome. Rock solid braking, no fade, no brake dust, and looks sharp, I get comments constantly on the car and “the gold brakes”. Car has about 22k miles and no brake noise I’ve ever noticed.
I have not driven an AMG with steel brakes to compare, though
my only gripe (I posted about this in another thread) is they went to the puny sliding caliper in the rear... versus the prior generation 4pot. I’m sure the car is engineered to not need the 4pot rears but damn if those don’t look so much better. If I could find the parts and it was feasible, I would swap the rears just for the improved look
I ordered CCB because I knew I was not going to track the car. It may be naïve, but I am hoping these brakes will last 60k+ miles, which for me is ~10 years.
Unless your car is red, I would give up all other options (besides driver assistance 2) to keep CCB.
Like others have said, put them on the car and enjoy a better existence .
Fair point about the rear calipers though, bit of a let down. Maybe they jived better with the traction control systems, or more likely MB just squeezed out a bit more margin on the package.

I live in Seattle and this is BS. They just want to get you for those sweet, sweet $6,000 stealership brake jobs every 20k miles.
Most dealerships and salespeople are of little value.
Yes, there are a lot of bad sales people and poorly run dealerships, but there are also some good ones as well. Its a highly competitive business, which means it does trend to attract some scumbags.
Like anything, the more straightforward you are with a dealer, the quicker you can get through the scumbags to the competent people. Scumbags show themselves quickly when pushed.

It's more like you quickly find out if its an isolated incident of scumbaggery or systemic. The reality is that if you take an untrained dog and a trained dog and make them spend time together, you get 2 untrained dogs. If you see a scumbag in your travels watch for others because, even at the high rate of staff turnover there is safety in numbers.
I've had 3 GT3/GTS RS 911s with CCBs and if they squealed, it was curable with some hard braking (i.e. 40-50-60mph to zero). If you do that a couple times, it goes away. If the brakes are warmed up, you shouldn't have the squealing. The overwhelming majority of the time, there's no squealing to begin with; it felt like a handful of times a year kind of phenomenon. Never owned an AMG with CCBs, but I spec'd them on my 2021 E63s wagon. Feeling good about that reading this thread on their performance. The wagon I test drove had the standard brakes which felt impressively good too.

Why avoid them with a red car? The colors are too contrasting? I'm curious because I'm contemplating ordering a cardinal red 21 E63 wagon with CCBs.
Eh, I'm not a super aggressive driver. I am sure the standard brakes will be fine for me.
However... $6000 for a brake job!?? Seriously?
Parts are ludicrous from the dealer. Just remember FCPEuro.com, you'll get all four rotors for the price of a single front rotor at the dealer. My CLS63 had eaten its first set of brakes by 24k miles.
Also remember that traction control, ESP, or whatever it's called on this car, will engage a lot in comfort and Sport modes and even more often than I'd like in Sport+ mode. This will lead to the rear brake pads wearing before the front if you have a heavy right foot.
I switch to Race mode or put the suspension in Sport mode before hitting my favorite twisties to keep TC from engaging too much.
Typically speaking, how long can CCB brakes last if you’re not tracking the car? I’ll admit that they look great and it sounds like they perform well in all driving scenarios. I’m just curious that if they can last 60-70k miles, they can practically pay for themselves?

if you’re not tracking the car hard and/or too often, basically the life of the car. Over 100k easily.
