Hoping to get a perspective on the Carbon Ceramic Brakes. I'm under the impression that the cost to maintain carbon ceramic is significantly more than the standard breaks and daily (non-track) use can be annoying (noise when cold, excessively grippy, etc.).

I've never had these so I'm not sure how much of this is myth vs reality so I'd love to get some feedback from this group especially from those who have received their new M cars.

Thanks in advance!

I have never had them so I'm not completely sure if this true but iv been told you need to keep heat in them for them to grip properly and that for street uses they will last "forever" but they are crazy expensive to replace like 10s of thousands of dollars if your not racing the car the steel brakes are more than enough for the street again iv never had them but if the cost is true I personally wouldn't want to pay that the steel brakes are expensive enough

If you are questioning them then that means you don't need them. If you don't track the car and want to ball out the benefit is they can last the life of the car and you won't acquire any brake dust. $9,000 is a lot just for bling and clean wheels.

Grip is the same, they squeak when the car is washed and it's cold out, you lose some braking power in heavy rain. Benefits are they don't overheat if you do a few track days but will significantly reduce the lifespan. If you are a heavy track user it is better to get steel brakes.

I agree if you have to justify it, probably worth skipping.

Good friend of mine got an F80 with the ceramics (disclosure car, got a great deal). He just about had a heart attack when he had to replace his rotors after 60K miles and wound up trading in the car. I want to say the quote was in the $25K range.

Being driven in the winter it was a challenge to remember you have to stand on the pedal a lot harder when they are cold. Completely impractical for winter driving.

Most of the GT3 owners I know replace the carbon rotors with steel when its time to swap out.

Yeah, if you're buying CCBs to have clean wheels, that's just bananas. LOL

And as a daily, they don't make a ton of sense.

But as a weekend warrior, with lots of spirited driving, and some occasional track days (and not full track days, but you know, 10 laps or less here and there), they may begin to make sense...because then they'll last a long time (could be 10+ years).

If you're already getting a steep discount and want to throw them in, it makes sense. If you're buying a $100,000 M3 with CCBs, well, I guess you just have money to burn...and I can't hate on that.

Appreciate the input.

25! LOL. That must have been BMW price. If you go aftermarket, it would still be expensive, but less than half of 25. Unsprung weight is also a big deal for some peeps.

I just went to the 2 days M School in Greer, S.C. and they said a brake job was about $17,000.00 The cars had ceramics on them (M8 and M4) and steel on the M2s.

$25k? Sounds high.

It's certainly common knowledge that the cost of carbon-ceramic brakes is high, but these stories about ownership and replacement cost have gotten exaggerated.

First of all, in normal road use, the discs *never* have to be replaced. Outside of heavy track use, they're designed for 300000km life (186000 miles) which--let's face it--is far longer than most of us own these cars.

Second, a full set of replacement discs for a F80 costs about $15k (just check a site like ECS Tuning). Figure another $800-1000 for a full set of pads. And the replacement itself is a job any one with a $100 Craftsman tool kit could do in their driveway in about 90 minutes.

Given that the brakes are about an $8k option from the factory, the replacement cost of parts at "only" $16k (2x the original cost) makes this a pretty reasonably-priced service job. It's not uncommon for OEMs to have far higher markups on service parts.

Having said all that, the brakes are undoubtedly a huge expense, and each buyer will have to decide for themselves if it's worth it.

With dealer labor, that sounds about right, and not unreasonable.

How much of a disadvantage are they on a day to day basis in colder temps and wet weather? Is it minimal or very noticeable?

I will daily drive 12k miles/yr and do 2-4 track days a year. The idea of less weight, less dust, long life, best track performance, and great looks is enticing.

Am I wrong to think they'll last >100k miles in that scenario?

For 2-4 track days per year I don't think it's worth it personally. The standard brakes are very good and would be even better with dedicated track pads and more than sufficient for a casual track day goer.

I'm not sure about the longevity but they could become something that people would avoid in a second hand market. You're not going to want to buy this car in 5 years second hand if it has a $20k brake bill coming up

Or do what everyone else does and replace it with standard brakes for less than 5k.

Yeah I would think you can drop in some OEM or nice Brembo or Stoptech if it came to that. Is there anything about CCB system that doesn't allow you to downgrade to steel in the future?

Just read through half of this thread and I'm pretty sure I'm scared away from CCBs now.

I'll just keep having a conversation with myself. The caliper clearance with 19" front wheel is pretty bad. Anyone have any good photos of this?

What do you mean by clearance? On the OEM set up? Surely it's OEM and that's the way it is designed? Do you mean for rocks getting stuck or something?

Yes correct, rocks getting stuck and scraping the wheel. From searching, this is sometimes an issue with CCB on the F80. Clearance on G80 looks no better.

Definitely was on issue on my F82 with CCBs. And it was quite hard to dislodge, without raising the wheel off the ground.

I wonder if a pair of 20" rear wheels with rear tire sizes would fit up front. BMW should be doing that for CCB optioned cars.

Ditto, but they cool
