Audi ceramic brakes
Discussion
They're expected to but other things can kill them just as easily. A careless fast fit employee changing a wheel could smack one of them trying to mount a tyre, a small rock could trap itself between the pad and disc, cracks could occur around the drilled holes which Audi say would render them useless.

That sounds expensive, thank you on youre replyMaxem888 said:
So i found some information that Audi's ceramic brakes last more than 100 000 miles (depending on how you drive)
Now, is that correct?
They were talking about an RS6 C6 with ceramics, i know they're quite expensive, but if they last more than 100 000 miles that changes things.
I've got them on my Boxster and as previously stated extreme care needs to be applied changing wheels as they can be damaged easily. There should be long studs somewhere in the boot (at least there is with a Boxster) which help guide the wheels away from the discs.Now, is that correct?

There is a lot of debate about ceramics but if you get them on a secondhand car they are worth having provided the car hasn't been tracked to death. They keep the wheels clean too.
According to Porsche on the fairly lightweight Boxster they should last for ages so 100000 miles on a road car like the RS6 should be easily achieved. I am a great convert to them but shudder at the replacement costs.
If it's tuned it'll still eat the brakes if it's asked to make big stops regularly. There's a process for confirming condition which looks at cracks etc (not all cracks are bad enough to require replacement) and wear, but eventually boils down to weighing the disc off the car!
The bill for replacement front discs and pads on an RS6 will reach well into 4 figures once you've replaced some hardware along the way (pad fitting kit, guards etc)
If you see a perfect spec car with ceramics which fail before you're prepared to stump up for replacement you can retrofit steel components although it requires a brake master cylinder and recoding of the ABS. not cheap, but cheaper than replacement ceramics!

Yup, dealer needs to be incredibly careful fitting them; if they're dropped or thumped down on a work bench that could spell the end of a 2k+ disc.Some light cracking from the holes on the surface of the disc is normal (and there's official guidance as to what's safe/not, TT?) but they shouldn't be joining between the holes.
