Rust of PCCB discs

[tophamn]

Seems to be only on Taycan because brakes are used often due to regen braking. I think PCCB on cayenne are nice and shiny. Mine kinda looked like that but after a couple of hard stops, they became much smoother and shinny looking.

My Panamera PCCB discs looked exactly the same.

Maybe AutoX meant "nice and shiny" PSCB

I had the same issue on my old 2020 model Turbo S and on my 2025 Turbo GT
Porsche hasn`t done anything about this issue in 5 years

What issue?

Rust / corrosion is leeping from hub to brake disc
No big issue because brake pads remove the rust during braking, but not nice looking at

My detail shop uses Gyeon Iron to clean the wheels and brakes. It's compatible with carbon ceramic rotors and removes iron particles/rust.

You couldn't make this shit up. Here are my aftermarket PCCB (and by that I mean Chinese Stopflex instead of Porsche Brembo) after 2 years of usage in Thailand's very wet weather. Not a single sign of rust

1/4 the price of genuine Porsche PCCBs

Try to use your car all year in Norway with all the salt being used on the roads in the winter time + a lot of rain throughout the year as well

I don't know about the salt, but in terms of rain and humidity Norway isn't beating Thailand any time soon!

Couple times a month I have no choice but to drive the car in 15-30cm of rainfall flood! Surely that would rust them worse than any possible rain in Norway!

Serious question: why are you running aftermarket PCCB discs? - what happened to the original OEM discs?

Why would I pay Porsche $30,000 (which is what speccing PCCB costs here)

When I can source these myself and install them myself for $6,000

I'd be a fool to gift Porsche $24K

Let me re-phrase: why did your car need new/replacement ceramic discs?
