PSCBs on a Cayenne

[AW10]

I’m looking at a 22 plate Cayenne equipped with PSCBs. The description sounds good (greatly reduced brake dust, virtually no fade and longer life than conventional cast iron) but I have not been able to find out just how long they are expected to last save for a Car and Driver article saying 30%. Their replacement cost is quite high according to https://teile.com/en/porsche-parts-shop/model-Caye... That’s quite a price to pay for less brake dust and only a 30% increase to disc life.

Does anyone have any real world experience with PSCBs on a Cayenne? I appreciate they’re heavy cars and brakes and tyres will be consumed at a rate of knots but brakes that dear that don’t last proportionally longer seem a bit pointless. So insights welcome.

Done many miles on the white calliper PSCB’s over two cars (both turbo cayenne). Excellent stopping power, no fade, little (if any) dust. Not much against them but they do sometimes squeal.

Thank you for this but can you please quantify how many miles?

Thank you for all the posts so far. I have also seen some posts on Rennlist with some higher mileages Cayennes and people have had no issue with the PSCBs.

I have PCCBs on my Boxster GTS and am very pleased the original owner specced the car that way. As it’s a fair weather summer car I’ve never really used them in anger in the cold and wet. I would chose them on a Cayenne if I could.

I drove the Cayenne with PSCBs yesterday and when cold and wet they did catch me off guard approaching the first roundabout at speed. Not a brown trouser moment but definitely raised eyebrows as more and more pedal effort was required before they began to bite as expected . After that they felt pretty normal.
