Only the rotors are ceramic. The calipers are some sort of alloy(probably with ceramic pistons) and ceramic brake pads.

Sure... IF you have need new rotors the "kit" might be the way to go for a measly $1K more.

Oh I see. But the 10k is for all 4 brakes lol in the set/kit. The rotor is 4500 each then pads are 600 each so you're looking at either 18-20k to replace all 4 rotors and pads or 10k for the entire thing and "free" calipers. Or am I missing something? Seems strange.

Not sure where your $10k for the CCB retrofit comes from, but in Canada, it retails for C$19,300.00. The kit is still cheaper than replacing the rotors and pads at the 4 corners and you do get new calipers for free .

That's amazingly cheap. The best way to replace CCB rotors for existing CCB owners IMO.

That's what threw me off a bit. Owners were saying how it cost them 17k or so to replace just pads and rotors when you can get everything and free calipers for almost half that lol

FYI, that isn't a full retrofit kit. It doesn't include the booster and all the stuff. See here:

The issue is heat. Heat, beyond a certain point (which no-one seems to quantify) causes the carbon fibers to oxidize (causing them to weigh less) and lose strength.

So, with CCB rotors, there should be a massive payback for brake-cooling ducts that can keep the rotors "properly" cooled. The problem is that I've not seen what would constitute "properly" ... but it's a given that cooler means longer life, all other things being equal.

So that sort of says that there's a significant safety margin designed into the CCB rotors and/or their wear specs.

Wow, that's a (positive) biggie. Still, it only makes me feel a little better because everything else I've read implies that CCB rotors can (and likely will) fail catastrophically if pushed past their specified wear limits.

This car has TiKT brake-cooling ducts and the front rotor temps are overlaid onto this video. Lap after lap, the car drops 200+ kph (125 mph) under heavy braking. The brakes hit over 800 deg C and are over 500 deg C for a significant portion of the time. Apparently, the pads are a special RSC formulation that they have worked with Pagid to develop.

No.

The disc type on the AMG GT R Pro is different than the Gen 1 MCCB. I couldn't have been more clear. Neglecting to utilize all the info provided…thats on you.

The discs on the car in the video you used have a higher percentage of carbon and have a longer oxidation life. The temp boundaries are the same however, and rather obvious by simply observing the color change at the respective temperature points. TBH, it appears to have too much airflow to the discs.

If you take your car to the track your CCB pads will evaporate at the rate of 1-2 mm/track day. I also somehow got a chip in one of my rotors and was told it was damage not due to wear and was not covered under warranty. The price for new front rotors alone: $11,000. I switched to girodisks all around for about 3K. Anyone need a set of rear CCB rotors and pads?

Anybody who replace rotors?

Hello, considering the cost of new CCBs
Someone replace steel roters instead of Carbons
The other type of BMW performance big rotor kit is consist of steel rotors
It seems that calipers are the same as CCBs, maybe not the pads as CCBs

If there is someone do this with steel ones. please let me know
how much would be the cost difference.

Regards,

Regards,
The CCB rotors are currently about $3800 USD each, so most either buy what they need used off of eBay, or a full kit from getbmwparts.com for $12,600 USD, and sell the gold calipers to mitigate the cost.

The CCB package uses the same caliper as the ///M Performance package/M2C/M2CS.

For those who prefer to keep their CCB (carbon ceramic brakes) and want to avoid converting to steel or buying new, there is a happy medium: refurbishing the ones you already have.

If you're considering the CCB option when purchasing a new car, keep in mind that the option below can reduce your cost of CCB ownership.

The option is refurbishment. There is a wealth of scientific knowledge behind carbon ceramic brakes, and there are many compelling reasons to own this technology. The main concerns are cost and wheel size. If anyone is interested, please send me a direct message. Additionally, feel free to subscribe to my dedicated Carbon Ceramic Brakes Facebook group, where I provide a wealth of information.

I hope to hear from you soon.
