How long are CCB expected to last?

Hello
3.1k for OEM PAD BRAKES

I had a gallardo lp560-4 with iron pad brakes and i need new pad brakes after 2,5k miles.

Track day, traction control OFF

Off topic, but what sort of life are people getting out their conventional steel discs and pads?

Its interesting that the 2nd most expensive car in Audi's range is being discussed here, yet not a lot of owners really know when these so called 'life of vehicle' brakes should really last for.

The official line is that they will last 4 time longer than steel discs, which are rated at 6250 miles or 6 months, which ever comes first.

Yet, a quick poll of the dealers salesman, seem to believe from 40k, to 60k, to 'well over 100k miles.

No where in the brochures, from launch to now does it say anything about longevity.

I imagine that as some of these cars are getting to 3 years old, there will be some unhappy owners, and some happy dealers. Your car may be about to lose £12k plus in trade in value!!

Cheers

how long is a piece of string ?

how can anyone tell you how long they last as its entirely dependant on how they are driven

What do you mean the discs are rated at 6250 miles or 6 months whichever comes first? That's not the life expectancy is it? Sounds more like their warranty period. How can you rate the life of a disc on time? So if I don't drive my car for 6 months I should still expect to replace my discs?

Well it has been 3 years plus now that these cars were launched and sold to the public.

Has anyone had any discs or pads replaced as yet?

Any problems or issues to report?

Cheers

I know many Porsche drivers that take CCB off and put steele on from delivery. I am not sure this would be an option on the C7?

Even so, why would you do that when you paid £12,500 for the priveledge to have them in the first place? You wouldn't do just to look after the car for the next owner surely....

For serious track day work yes. Aftermarket steels like Alcon are better for heavy use and handle heat better - way cheaper too. Ramics then go back on for road. Lots of GT3 owners do this. I never had ceramics on mine but still used aftermarket front brakes for track days (standard Porsche rear brakes can take almost anything thrown at them).

This whole subject is totally down to how you drive. Like the Russian guy who cooked a set of ceramic discs on a track day and went down the warranty route with Audi and won.
I saw that car and even the calipers had turned gold due to the massive amount of heat generated.
I'm on my third RS6 never had ceramics and don't think you need them. IMO

Agree. Nice to have if money no object, but not required on road, and a potential liability on track if you push hard.

The more advanced ESP systems which are now deployed across the RS product ranges utilise the brakes (torque vectoring) to trim the car for better handling/performance. So I'd expect the longevity to decline a bit more, but I still think approaching 100k miles with normal road use, wouldn't be an unfair ask from the Carbon Ceramics on the RS6.

I stand to be corrected, but I am fairly sure the RS6 uses a proper torque vectoring rear differential (which uses clutch packs to channel the torque). It doesn't use the brakes.

From my understanding, you are correct to some extent as the Sports Differential is the mechanical layer underpinning the system at the rear. Complimentary to this are two electrical layers, the first is an Electronic Differential Lock which has an electric controlled hydraulic actuator. This delivers the required rate of lock up to the clutch packs via the myriad of sensors feeding the control unit. Secondary to this layer is the Electronic Stability Programme, which can further trim the cars 4 corners independently via the braking system.

Yes, that's my understanding, too. But when the brakes come on, that's ESP and no longer torque vectoring. It is also the shift from the car using technology to help you go faster and safer to the car using technology to help you go slower and safer.
