Porsche ceramic composite brake possible saviour.
Discussion
Just a quick question.
As most PCCB disks seem to fail due to hairline fractures that are contained to the very surface of the disk, or as one recent thread shows delaminating of the disk, is it possible to resurface the disks?
I ask because I have an engineering company I use to resurface steel disks, and they do an amazing job, has anyone even tried it with a PCCB and is anyone game to try it?
Basically if anyone has a scrap disk (forgod sake make sure it is otherwise going in the bin, if it gets destroyed in an attempt I ain't going to buy you a new one!) that they are prepared to take a chance with then send it to me, I'll see if it can be done and if it can then you can have your disk back refurbished!

Umm, so what are they going to resurface it with?
(I don't have one by the way.)
Slippy may well be able to send you his BUT it would take a brave man (or woman) who would be prepared to test the brakes following their refurb (I am not suggesting that your engineering skills are anything other than of the highest order - well I hope you know what i mean)
would love to find out how you get on because you could develop quite a sideline

The construction of the PCCBs is made up of a thin ceramic layer formed onto the main "body" of the disc (which is formed out of a mixture of silicon carbide and carbon fibres, more details on the properties of silicon carbide can be found here : www.accuratus.com/silicar.html )
The ceramic layer is formed by coating the carbon fibers with a silicate in a high-vacuum process at 3,100 degrees F (1,700 degrees C)
My understanding is that once this layer of ceramic has been overheated (temperatures in excess of 800 degrees C) whilst in use, it starts to break down and eventually fail. This failure culminates in the ceramic layer de-laminating from the silicon carbide/carbon fibre "body" of the disc leaving an incredibly hard and abrasive surface capable of grinding away a set of brake pads in less than 50 miles.
Thus once this ceramic layer has been damaged or started to de-laminate the disc is effectively scrap.

So basically you need a paint brush, pot of ceramic stuff and a blow torch.

How stupid can you be ?
You need a bloody good vacumn hoover too (it says it's a high vacumn process remember)

If they are built as said with a skin over a sub structure then tbh its highly unlikely that anything can be done, however depending on how deep that layer is it may be possible to fetch a few thou off the top surface and leave a clean braking surface. It should certainly help with the disks that are starting to fail i.e. small cracks forming, if not with the major delamination that some suffer from.
Another option is to reapply the ceramic, I deal with a couple of companies who ceramic coat certain items to help with heat dispersion, although I'm sure its not the same ceramic who knows they may be able come up with solution for this.
I'd approach an OPC for a scrap disk but something tells me when they find out the reasoning behind it they may not be so helpful!
