Porsche 911 Ceramic Brakes
Discussion
Hello PHers,
My Dad has been on the look out for a 991.1 C2S for a long time. It will be his first 911, and he has found one in the perfect spec for him - guards red, PDK, Chrono & Sports exhaust etc...
The car also comes with carbon ceramic brakes (PCCBs). I have read that this shouldn't be a problem and they should last over 100k of standard road use. With this vehicle on 30k all seems fine. We did note that this car had Porsche dynamic engine mounts and the optional sports seats, and along with the brakes it seemed like it had been specced for particularly sporty driving. Taking a look into the MOT history has revealed that about 6 years ago the car had an MOT in which all four tyres were advised as worn, and brake pads were also picked up as in need of replacement all at the same time. All of this seems to suggest track use to me.
In recent years the car has done only 1500 miles, and now reports slightly cracked tyres, suggesting that its usage has been low and not on a track. With all this context, should this be avoided for the risk of a big bill, or are the PCCBs not as scary as some may suggest?

There's an easy process for measuring remaining rotor life with PCCBs. If you look in this thread and read from 13th February, all will become clear: https://www.pistonheads.com/gassing/topic.asp?h=0&...

Though maybe not of this era ... this car will be pre-my 2011 CR which had the earlier generation PCCB's ...
They can be refurbished if they do fail (though not by OPC's who want to sell replacements at vast cost) ... ask JZM first ??
On the other hand, my CR discs failed at over 30,000 miles and I had done a lot of trackdays ...the cost at the time of a good refurbishment was Euro 2k ...
I will add a picture of a failing disc but I would imagine that these should be good. If all four tyres had done 20,000 miles from new that's comparatively gentle driving and the normal life was / is in excess of 100,000 miles ... with all the advantages of no disc corrosion, jammed pads, brake dust, unsprung mass ... etc ...
The delimitation of the surface layer can clearly be seen, first noticed as little triangles dropping out of the surface revealing the substrate to which the surface layer is bonded ..

Certainly the 2015 PCCB's were Gen 3 ... and the Gen 3 PCCB's have been proven to wear much better than the Gen 2.
If Gen 3 then a local OPC should be able to measure the wear with this:

If Gen 2 should be good with the wear as suggested, then Gen 3 will certainly be good.
