I have a 2017 Cayenne Turbo S and it came with PCCB, i never took my car to drag and i have driven almost 75000KMs within this period i changed my front and rear brake pads twice, i don't know how they are finishing quicker than expected but i live in UAE and there is alot of sand that comes to the wheel, however it costed me 2100$ to change both front and rear pads the first time and second time it was 2300$, honestly i only see a difference in braking performance but in reality if your not going to drag alot then its best you just get normal discs and pads, FYI each Rotor costs about 5500$
Stupid question. How are you guys backing off the brake pads. Normally on my other cars I would just use a large screw driver against the iron rotorface but I feel like that would not be a good idea against the ceramic face.
Remove the pads and you should be able to press the pistons in by hand one at a time, they are small diameter. Also make sure the brake reservoir cap is loose so the air can escape when the fluid gets pushed up to the reservoir.

Yeah but it's a monoblock caliper, can't pull the pad out the rear. I would imagine you need to back the pads off a little to get over any lip that would be created on the rotor face.
Ceramics don't create any type of lip. Porche calipers must be removed to get the pads out because of the guide pins. Caliper will pull straight off, remove the pad and press the pistons in by hand, super easy.
Unless you track the car more than a few times a year or get unlucky with a nasty, wedged rock or other debris between the rotor and wheel/shoe or score a tire tech who is a clutz, they will most likely last the life of the average car and beyond. Pads will go, disks will not. Particularly the Gen-III version on the 2017 and later cars shown below....
Your mileage may vary, but unless you are SchlepRock, they will be the last thing you worry about EVERY TIME YOUR FOOT HITS THE SLOW PEDAL. Neck and neck with FBs and with RAS for best block checked.
EDIT: Just saw your avatar, looks like you have them... If so, forget the above sermon as you undoubtedly know already. Are you having second thoughts? If so, don't. You'll love them for all the right reasons and soon forget what you paid for them.

They're worth it to me because they do last "forever" with street driving and NO BRAKE DUST! Thats my reason.
Only 27k miles on my 991 long way to go will report back on that.
But for reference my macan turbo has 85k miles on the ceramics and during the recent annual service they said she’s got a good few years left on them. Time will tell but I do love the brakes for every day use.
