Just my thought.

Change to slotted floating Brembo in front if you track it. Even if you don't track they are light and you will not have problems. Try to foster a good relationship with your Porsche tech and service department. I can say without reservation that I would have had mine replaced under warranty; my fault or not.
Current Setup:
MPSC
Schatz Alignment
Cup Brake Ducts
Brembo Slotted Floating Rotors (front)
RS Flywheel/Clutch
Tequipment Roll Bar
GT3 Cloth Seats
BK Driver Side Seat Brackets
Sabelt Harnesses
Center Console Delete

In the end its just cheaper to switch to alcon floaters if you are based in the uk (try JZ Machtech) and forget about it. We all know ceramics have a reputation for degrading so a replacement set won't really help in the long term.

Paulrothwell - if you do a search onthis forum you will find lots of people who suffered failures with Gen 1 PCCB, including me. Mine lasted longer than yours but failed the same way. Locally, I know two others who had the same problem. Porsche may be sympathetic.
The real solution is to replace the front rotors with 996 GT3 350 MM steel rotors. Replace the rear ones with 997 GT3 rear rotors which are the same diameter. You will be able to retain your original calipers. You can buy the rotors from US suppliers for less than 400 US dollars each.
Colm I beg to differ but if the Gen 1 was without fault, why are the Gen 2 PCCB so different?
Regards,

My 05 GT3 has gen 1 pccb I've been told vin ....2074. My rear rotors appear to be smaller than the fronts. I thought the 05 pccb cars had same size front and rear. Is there anyway to distinguish Gen 1 fromGen 2 ??

Evolution my friend!
Following your logic would suggest that all previous Porsches (and products) were faulty because they were updated.
Now riddle me this one?
Why is it that Factory (all) race teams take lots of spares, and spare cars to the track; but individuals (even some who aim for race type times) expect to subject their cars to some of the same repeated track pressures and expect magical performance (and warranty)?

Thats the thing though Colm, they take spare ceramic disks too. Thats not quite how Porsche marketed this tech, and certainly now how they priced it. Riddle me this - why are they a 5k GBP option but 13k+ GBP to renew?

The pics showing a red hot disk with claims of being able to withstand the harshest track conditions were pretty explicit though! I know the brochure is now covered in disclaimers, but it wasn't back in the day. Hence why early buyers who bought the car new get a lot more loving from Porsche if a complaint is made...

We’ve been ill advised and Porsche AG KNOWS that!

The Gen I brakes are inferior to Gen II, however if treated with respect and with maintenance the Gen I brakes are very good and will last a long time.
I believe that this was Porsche's fault only on Porsche not expressing the need to change brake pads frequently.

Some PCCB info:
Thicker carbon fibers now, actually, they're fiber bundles
Three thousand fibers were previously (Gen1) used to form such a bundle;
the new generation (Gen2) has 400,000
While the 20 air outlets in the first generation are oblong, the new ones are square.
There are twice as many outlets now as before. The perforation pattern on the braking surface has been changed as well. It used to be regular. Not it's more random.
