Clearly not - bloody expensive for a consumable item!

Someone should make steel discs of the same dimensions as the ceramics for a direct fit replacement. Even at a few hundred £ it would represent an affordable and economical solution to worn ceramics.

Is there a recoating solution?
How big are they, 420mm? I know you can get 400mm discs on the D4 which *may* use the same caliper (with different pistons?), but they ain't cheap either.....

In summary, i think its probably fair to say that ceramics would expect to last 3 to 4 times longer than steels. To suggest that any braking system could last x amount of time, or y mileage, suggests Audi can control how its driven, which of course they cannot. I think the RS cars in their very nature are driven harder, more of the time, rather than sat (Wastefully!) chewing up motorway miles, so you get this apparently large discrepancy between expectation and reality.

The rear steels and ceramics are the same size. They will bolt straight on I'm told.

The front ceramics are 420mm, where the steels are considerably smaller.

I had wondered about a steel bolt on replacement, but ceramics are very light - a 420mm steel disc is going to add some serious unsprung weight to the car.

I've had a lot of interest in the car, and I've got a couple of offers close to what I need to sell it, but not close enough.

It interesting. There are most definitely 2 camps of people when it comes to the RS6:

1) Poweeeeer. They see this car as a pretty, carbon dressed, MRC tuned monster and are delighted it has ceramic callipers, but want it cheap to be able to sort the ceramics out. It'll spend every weekday in the garage, and the weekends going sideways. Factory options just add weight. Shame its got so many of them.

2) Spec. Mr Executive. Wants a really high spec, good looking Audi for daily use, and wants every overtake and B road to put a grin on his face. Sees ceramics as a costly ticking time bomb and really wants a car with everything, apart from those.

If I were to prepare the car for resale properly, it would be ceramics off, factory spec steel callipers and discs on. Its a no brainer. Net cost is about £2k I expect, and then it would appeal to Mr Executive, but no longer would interest Mr Poweeeeeer !

I'm approaching 100k on mine and was looking at options to replace the carbon ceramic brakes. Haven't found anyone able to do it reasonably yet.
