2014 CCB
Looking at purchasing a really clean really low mileage F10 m5 with CCB package. Car has 30k miles and the I drive states 4,100 miles for front pads and 15,000 for rear pads. Visually the carbon rotors look great and the car has never been tracked. I'm under the assumption these brakes will
Last a lot longer and maybe the service mileage is low due to the vehicle being 5+ years old?? Any help would be greatly appreciated. Thanks!!! |

I think the only way to be sure about the Ceramic discs is for them to be weighed. The pads arent too cheap either I think.

If you take the car to the dealership, they can tell you the true remaining life on the ccbs. In general the cars computer is calculating useful life based on in service date and not true usage.

There is an impregnated mark on each CC disc showing you the state of it, if it's showing proud then your fine, if nearly faded then they're reaching their end of their service life.
The pad thickness is easy to see from the car of how much they are worn. |

IMO, at 4100 and I would steer clear of the car, unless you're cool with dropping $7k on new rotors in the next 12 months. I would also question why a car with 30k miles only has 4100 left on the front CCBs AND supposedly have not been tracked. It's a clear indication the car has been tracked or the braking system has been used very hard. FWIW, I recalling looking at a 30k M6GC with CCBs and computer said there were at least 18k miles left IIRC, which at the time I thought was a bit higher than average wear for a street car. I want to say for our cars, CCB wear for street use probably should last around 60k-70k.

From researching CCBs, the consensus (that I found at least) is that the rotors should last close to 100k miles with just normal street driving, with the pads at ~50k. I'm super easy on my brakes and by the amount of miles I usually put on a vehicle, I'll be an old man (43 now) before I'd have to swap them out.
