Carbon ceramic brake discs - refurbishment now possible.

[Schermerhorn]

Hi guys,

if you have carbon ceramic brake discs that are now fairly old, rope and don't work as good as they once did and DON'T want to spend tens of thousands replacing them, there is an option to refurbish them to as good as new, if not better.

SICOM in Germany offer this service. The old discs are machined, levelled and a surface polymer layer made from carbon silicon replaces the worn away surface. The results are fantastic and braking just as impressive. All for 25% of the OEM price. A 12 month warranty is also given.

Here is a Ferrari F430 that recently had them done

There is also a running discussion on the Porsche forum about these discs and the refurbishment process.

As standard, every new refurbished disc will get new nuts and bolts.

Regarding the refurbishment, the process is something like this

- Discs are weighed and depending on wear and wear pattern and rotors are x-rayed and examined for structural damage.
- Brake pad residue or contaminates is chemically steamed off
- Discs are machined until they are level
- Napped are vacuum soaked in polymeric carbon
- Pyrolyze the discs at 1100°C
- The last two steps are repeated three times
- Discs are siliconized at 1500°C
- Top layer (ca. 1mm thick) is now restored, and trough the pyrolysis it is chemically and physically bonded with the structure
- Final sanding of top layer
- Disc is reassembled and weighed once more and precision-balanced
- The disc now has gained about 30-50g and is at desired value once more

I've copied and pasted this from the SICOM site as it's more elaborate than how I would have been able to explain it.
