I wonder what you guys do when your pccb is due for replacement on your 996/997/GT3?

1. Replace with iron rotor
2. Refurbish the discs
3. Replace CCM rotor ring (not sure if available from Porsche dealers)
4. Retrofit to oversized ccm rotor kit
5. Upgrade to a complete CCM brake kit (including calipers)

I am curious to see replies. In all my years of roaming this forum, I have never heard of anyone replacing the ceramic rotors due to wear. Their longevity seems to be extreme.

If you replace your pads before they become too worn, then you will preserve your rotors. That's what my mechanic tells me anyway. My PCCBs are showing very little pad wear at ~40K miles.

I'm curious too. I think if not tracking the car then the rotors will likely last 100,000 miles if not longer. As Dennis says, my setup still looks brand new at 47,000 miles.

No one ever replaced pccb rotor rings?

Never out-brake pccb rotors or because of no availability.

I asked my Porsche dealer about this on my last visit. He told me that he has never replaced a PCCB rotor because of wear. He said he had replaced some because they got "burned up" in heavy track use, but that's it. PCCB pads, on the other hand, need to be replaced as they wear.

Almost 12,000 miles on mine, I've heard they last 100,000 miles, it'll be long gone before then. No plans to get them replaced, will replaced the car before PCCB's.

So what your mechanic specifically replaced - to iron rotor assembly or just the pccb disc?

Dennis C

I don't know the answer to that, sorry.

RacingBrake

Correct me if I am wrong - Dealers don't sell just the replacement disc, only the complete pccb rotor assembly.

If that's the case may be due to availability so no one is replacing the discs?
