Not sure about the rears, but the front pads for use with ceramics cost me just under £1k (fitted) at an Aston dealer (on a V12V)

They don't need warming up like the carbon brakes on a race car (which are a different compound completely) as in they don't need bringing up to temperature to work. They do work a touch more effectively when warm, but there are no problems with them before that point

I asked why as it seems an awful lot of expense and work on an 11 year old car for very little, if any, real world benefit.

If you are going to drive that car very hard then you'll also need modified air ducting to the braking system. On a regular metal disc cooling air is ducted to the disc. On a CCM system cooling air is ducted to the caliper.

Try and have a look at a V8 Vantage with regular discs and another with CCM to see this...

Don't forget all of your cars electronic wizardry is set up to work with steels not CCMs. All that will need changing too. It's been covered at length before.

Don't know why that'd be the case. I suspect the car has no idea (nor cares) what types of rotors are on the car. Lots or people swap steels and CCMs on Porsches and Corvettes w/o any such shenanigans required.

Ceramic brakes don't stop the car any quicker. They are just lighter and less prone to fade.

Also going the CCM way on my 04 DB9, all the kit is here for the front,I am also swaping the rear calipers for the standard front ones, not yet sure that it fits.
The only unknow issue is the need for a bigger master cylinder.

I'd agree with others on here - CCBs don't stop the car any more firmly than steel, although I guess that partly depends on which steels you are comparing them to - I imagine early DB9 steel brakes won't have the same stopping power as the latest Aston steels, if the spec has been upgraded over time

Main advantages would appear to be lack of fade and less brake dust. On fade, certainly on track or a really heavy days driving in the alps, bearing in mind our cars are front engine and not so light, fade can kick in. But that's very rare and I'm guessing, even rarer on a DB9 which is not the most obvious track car

I'm not suggesting it shouldn't be done - it's a personal choice - but if it's for stronger braking power, I'd be wary of such an upgrade having much impact. Of course for the OP with his great deal on the discs, it's a little different, although they could possibly be sold at a profit that would then pay for a steel brake upgrade

This is a long running thread going back quite a few years and I would be interested if any have done this upgrade how it impacted when they came to sell their cars. Does it enhance value or reduce it. Or, can it just be reversed?

I would think it would rule out trading in via the dealer network as they would struggle to warranty the cars and potentially reduce the pool of potential buyers. Of course, if the car is a keeper, that is irrelevant.

I have always hated the weak brakes on my DB9, I much prefer the ones of my DB7 Vantage.
I've been looking for improvement for a long time now,as I have 20" DBS wheels CCM is an easy upgrade.As I have no plans to resell I carry on improving my old beast.

Really interesting read, thank you everyone for your input. I pulled out at the last minute before buying the ceramics. Watch this space - back soon, I have a cunning plan

CCM discs and 6 pots calipers fitted at the front and standard 4 pots front calipers migrated to the rear, now it stops as it should.
