In my experience, replacing the pads when they have 1/4-1/3 of the pad thickness left has meant I've never harmed a CCM rotor; yet! lol

If you track the car hard this is really important IMHO, as the major costs associated with the CCM braking system is of course having to replace a rotor. It will be interesting to find out if the GT R's CCM rotors are the same Brembo CCM disc that is found on certain GM products like the C7 Z06/7. If so replacement costs will be far cheaper.

CCM brakes can make 'noise' on the street, but modern systems much less that ones from 5-10 years ago. Also, high performance iron brakes can also make even more noise when equipped with 'track' compatible pads. I have always been able to eliminate the noise from the CCMs on my Z06/7 by doing some rapid stops, although base line noise has been minimal to begin with.

I drove a GTR on steels on track today, they're not upto the job in my opinion. CCM is essential for anyone tracking this car hard.

I would agree. If you're going to drive this car to coffee and caffeine shows no, but if you buy this car you have to track it once or twice a year and quite frankly not having to replace the brakes in your lifetime or probably the next person in line is worth it.

What brake dust?

guynamedsean

ha. You're joking right? My car makes crazy brake dust!

AMG 17GT

No I think I probably would've gotten ceramics if I had to do it again I mean my wheels get destroyed every three days so I'm hoping for some Pads that fix it. I have spent 100 hours cleaning my wheels and I'm over it.

Anyway I'm happy with the black powder wheels coat for now......

guynamedsean

when my car got coated with C Quartz Finest, he did the wheels. Helps a lot!

thebishman

Not sure if you're 'tracking' the car, but if not Carbotech and other vendors make some 'ceramic' pads for the car I bet that greatly diminishes the amount of pad dust on the wheels. They just aren't a high performance pad.

I'm still on the fence.

Do the Mercedes carbon ceramic brakes have that squish that others do when cold? This is going to be a road car. I'll track it maybe twice in my life. Not dealing with brake dust sounds like a huge plus. So does not having to worry about corrosion on the rotor. But if the brake feel is weird/squishy under normal daily driving...

thebishman

In my experience, modern CCMs are perfectly liveable on the street. I for sure would get them on a car primarily for street use only.

I think I'll be replacing discs and pads on my ceramics.

I was "advised" that AMG steel brake can only last up to 30000km street use. I am not sure how realistic that is and the whole brake Pads/Rotors have to be replaced at the same time which can cost nearly 5 figure. Also, says for CCB, the only thing needs to be replaced is the pads.

I have/had owned several performance cars now and in the past, maybe nothing as extreme as the GT R, but all of them has/had steel brakes and not for once I needed to replace the brake during my ownerships. A few of them had gone as far as 70000km without needing to replace brakes.

It's definitely a nice upgrade, but is it worth paying nearly $16000 after tax? (Canadian dollar here)

thebishman

This sounds like typical salesman bull****. If you are just driving the car on the street the iron rotors should last many, many years. The CCM rotor should last the lifetime of the car when only street driven. Pads since they are high performance might only last about 20,000 miles on the iron brakes, and perhaps the same on the CCMs.

Bottom line: change the pads when they're getting pretty worn and your rotors when street driven only will last fine.

Road course usage: different 'ballgame'.

At delivery, I paid $1500 for a 5 year one time pad and rotor replacement on all 4 wheels, transferable. Would have never considered it, but my CL rotors were 1600$ each on front and pads.

The one year extension to factory warranty was also included.

thebishman

That is one hell of a bargain! Just need to make sure that the fine print doesn't list exclusions as long as your arm! lol

I had CCBs on my California, 458 Spider and Huracan. The brake feel is very good and stops on a dime and the absence of brake dust especially with silver rims is a huge plus if you clean the car yourself.

The brake squeaks are annoying and even with proper bedding can recur, for example after washing the car.

All 3 of the vehicles had CCBs as standard. For street driving exclusively, I would not pay the premium for CCBs and would use the money for the upgraded Burmester and Carbon Fiber trim. YMMV.

AMG 17GT

I read it very carefully . All the exclusions were very commonsensical excluding of course any track use or racing but you should look into that when you take delivery at that dealer and the extra year of warranty on the car is a real bonus

I also paid 2000 for any wheel and or tire damage for five years, as I broke two wheels on my CL in Atlanta. Also transferable.

What about rotors rusting? I live in San Francisco. Right on the water. It can get humid here so I want to keep my wheels from looking like this:

How old are those rotors?

I live 2 blocks from the ocean and have never had an issue with rotors looking like that, even steel ones on vehicles 5 to 9 years old. The ones on my 5 year old 911 had no rust and that was after 20000 miles of daily driving.

I've never had to replace calipers or rotors but it would still be a lot cheaper to get a new set or two of steels than pay for CCBs up front I believe.

FourT6and2

Good point on the cost for replacement I guess.

No idea how old that car is. Just a photo I found on Instagram. My previous car's rotors (Lexus) rusted. But I had that one in CT, NY, and MI where there were winters and salt.

surfah

For sure, I did my residency in Michigan and the road salt is brutal. I would specifically take my SUV to car washes that rinsed the underside of the car.
