[BMWF90M5]

So I do NOT have CCB's, but the brake squeal is horrible, only 10k miles. What are my options. I didn't see much when I searched for the non CCBs. BMW claims this is normal on normal brakes as well? I find that hard to believe. I've had a number of M cars and this is the first time i've ever had this issue.

Are there other brakes out there to switch out for that wont do this?

You really did not find any other posts on the subject? I read them pretty regularly. You can try different pads but no long term guarantees. Search for the most current recommendation but don’t expect years of use confirming no squeal over time to go along with it.

Yeah I was going to say…

Here's mine from earlier this year.

The answer to your question is this.... Don't drive the car

This has been discussed so many times its comical.

There is a handful of aftermarket pad options.However I don't think many have had them long enough to be able to accurately tell if they work or not. Many have had them for 2-5-10K miles and stayed quiet then started back up again. Some have had success but at the detriment of performance in braking.

Basically enjoy the school bus sounds coming from your 100K plus car. BMW has zero interest in addressing the issue. And you're basically stuck with it unless you're a lucky one who's don't squeak. Or able to find a good aftermarket option that works long term.

The process of getting the car to 60-80MPH and slamming on the brakes 3-4 times to dead stop seems to work. Although it is temporary, seems to last for the duration of that drive. And thats about it. Same with the wheel cleaner method. My F10 was the same annoyance. F90 is just as bad or worse than the F10. So again, good luck.

Sell the car and get one with CCBs. All of us CCB owners do not understand the extreme reluctance to buy them when you're in this price bracket and there are unbelievably extensive complaints out there about the steels being crazy loud and produce insane dust. I would only get steels on a track car so that replacing them would be at a reasonable cost. For daily driving, CCBs make more sense because they last a really long time, are quieter, and make very little dust.

It’s funny how carbon brakes were originally a high performance track item. Now people buy them mainly to keep their wheels clean and use steel brakes at the track.

I mean if money is no object, they're still the best brakes for the track. But few can stomach the replacement cost.

Agree 100%, except for the sell part, lol. Unless you can brake-even (see what I did there? ), I dont think its worth taking a loss to get CCBs.

I would prefer to find a used set of CCBs, or even aftermarket CCB rotors, that apparently work with the steel calipers. Racing Brake I think sells replacements in the steel size specs in a CC rotor and pad set. Someone else would need to chime in to see if these are worth a damn, and if its just a straight swap for the steel rotors to the CC from racing brake.

If I could have found one with CCB in the color, and options I wanted, I would have picked it up in a heart beat over the steel.

I guess the bright side is, for steel brakes they are exceptional as far as performance (in my opinion), of course, minus the school bus, rental Haul truck sound track that accompanies them.

The dust and squealing is literally one of the only things I cant stand about the M5, f10, or f90.

But with that said, the great things about the M5 highly outweigh the very few negatives.

100% agree. My next vehicle will absolutely have CCB, although living in AZ there is a lot of rocks and pebbles on the roads, would be marginally worried about picking up a rock in the caliper, and then? it's over for that rotor. But I would take that gamble over the dust and pig noises.

Every one of us can feel this.

That's a good idea about swapping the rotors and pads over to carbon ceramic if you can keep your calipers. I didn't know that anyone made a carbon rotor that would fit the M5 steel calipers. I don't know anything about the brand, but certainly worth looking into.

Agree that the steels bite hard and perform great.

💯 .. not cheap but worth every penny if you can swing it.

I briefly looked into it, but didn't spend a lot of time on it. Looks like about 12-13k for 4 rotors and pads.

It says "iron upgrade" or CCB replacement.

Someone with a lot more knowledge than I have would need to chime in as to if you could literally just swap pads and rotors and still keep the same master cylinder, coding etc. I believe in order to swap to the OEM system there is a bit more involved than just swapping pads and rotors. That would be sweet if its just a matter of pads and rotors and boom you have CCB.

Both are expensive. However the Racing Brake option could at least save some time and expense having to change calipers, coding, and other components (if thats the case, I dont know).

I know... completely embarrassing to pull up to a light or drive through and have it sound like I drove over a couple of baby piglets coming to a stop. But whatever... that all goes away when I hit the gas.

Me outside pulling in to the valet at Mastro's for a nice 100.00 steak....

"Nothing to see here everyone! .... I seem to have driven over a couple of pigs on the way in to dinner, ..... move a long, trust me, its fast, and my BMW service advisor told me this is normal, I swear....go on with the chlorophyll"

[ResIpsaLoquitur]

I got a really good laugh out of this! Thank you!

This was so extremely bad on my previous M5, I started the thread higher up in the post. Embarrassing was an under statement. I don't mean to revive the complaints in that thread, but it very nearly prevented me from going with another M5. Have had my new M5 for 3.5K-ish, and I am squeak free 95%+ of the time. That 5% is only if I am really creeping through city traffic at low, single digit speeds, drive through, etc., while holding the brake with light but consistent pressure, and even then, not all the time. A significant portion of the squealing is gone in this car (or perhaps just hasn't started yet). It's such an improvement I don't complain about the remaining squeal any more. No CCBs, just like my last one. There really seems to be no rhyme or reason to it.

Started before 1K in my previous car. I'm just hoping it stays like this. One of my other cars was quiet as a mouse until basically the second it hit 20K in the last month. I don't think I could take another one.

The Steel Brakes were updated for the 2023 M5's. They are supposed to be quiet. We'll see. The updated parts have been available at dealers since June.

Interesting. Would like to know what they've changed, but it's unlikely the technical details will be shared. If I had to guess, a different pad compound.

My 2023 M5 has 2.3k miles and have yet to have the break squeal. Maybe BMW has it fixed.

My 18 has 57k miles and have never had break squeal. Dealer installed OEM pads. My only complaint is the damn brake dust. Im gonna need to fork out some money to get those pads from RG motorsport.

Probably the luckiest person on this forum in that regard.

Same here after 1.5 years. Never heard a sound out of my steel brakes.
