In my experience Porsche OE brake systems are phenomenal, but I do not like the feel and modulation of the PCSB pad and rotor. I’d prefer standard iron discs, and don’t really care about dust.
Does anyone know of an aftermarket supplier for the Cayenne PCSB? For both the rotors and pads?

I don't think one exists. I think the calipers are from Akebono.
I emailed Giro Disc to see if they have a replacement rotors that fit, but have not heard back. However, the problem will be finding a pad that fits the caliper, I don't think any exist. Limited market, Cayenne Turbo, Taycan and I think Audi eTron uses the same brakes. The Macan uses a smaller size.

My understanding is the the upright is the same across all Cayenne, no reason to doubt that. That's the suspension component the caliper bolts into. If that's the case, you need to replace the calipers from a Base, S or GTS. A new hard line (couple bucks new), then you buy rotors and pads.
I don't know if the GTS brakes are larger than the S, probably not.

Used calipers are a dime a dozen and the best path forward.
Pads and Rotors and widely available as aftermarket, pick your poison.

Replacing the calipers and rotors is almost as common as an oil change, any ASE mechanic can do this. There is no special Porsche knowledge.

I recall a thread in here where the original PSCB’s sourced from the german 3rd party manufacturer was significantly cheaper, calling on @Schnave ftw.

3Series

That would be good to know.

~$7,000 for pads and rotors from Porsche
~$15,000 for PCCB brand new set that I see the bay as of today, which would probably be better than replacing with PSCB since you could sell them afterwards and it might cost less then PSCB, its just a limited market for the particular size.

Used Cayenne Calipers - $1,000
Porsche Rotors and Pads - New - $1320, aftermarket for probably half that and just as good.

So 50% off on PSCB rotors and pads might be worth it.

Also, retail price for these rotors at Audi for a 2024 RS eTron GT at a local dealer is $3500/rear and $4500 for the front. I'm sure you can get a discount but the point is that I don't think sourcing them from Audi is less expensive than a Porsche dealer like Suncoast or Sunset.

I am following this thread. I am looking at purchasing a 2019 Cayenne Turbo with 70,000 miles. The owner tried to get by with just replacing pads and the car has a significant pulsation. Then he replaced the front disc after I had a pre buy done. Still has issue pulsating, now probably from the rear disc need to be replaced now, unless it’s something else causing the pulsation. Even then, I thought these PSCB were supposed to last 30% longer? So every 70k or sooner, you need to spend $10k on brakes! Ouch! I don’t do any track activities and I don’t think the owner did either. Idk, that just seems like crazy money for pads and Disc/rotors. I rather deal with the dust and replace everything more often for less money.

i would not get a vehicle w ceramic brakes unless you are very comfortable throwing the money into them. I personally think they are a net negative unless you are serious and doing regular hard tracking w a vehicle. dust doesn’t bother me at all. ceramics are impressive, but ridiculous for common person to have imo.

Maybe it's not rotors? I had PSCB on 2019 turbo for over 80k miles of hard driving, and they were fine with no sign of wear on rotors. Iron brakes with comparable use needed to be replaced every 30K miles, so in my experience PSCBs lasted much longer than iron brakes.

Vapordan

No Schnave!

Here you go. It's resurface not new. My memory failed me. As usual.
Is it the same carbon ceramic brake setup across the VAG group? - Rennlist - Porsche Discussion Forums

CTE Carbon

This is something that our company can offer (OE replacement carbon ceramic brake discs and pads). PM me if you would like more info

On Suncoast Parts website, the PSCB brake parts are significantly less than the PCCB brake parts.

Front PSCB rotor set $3,544.88
Rear PSCB rotor set $2,695.00
Front pads $393.50
Rear pads $324.50

Brake pad sensor set (FR/RR) $80.00

The prices are definitely much more palatable than new PCCBs.

I may have a solution on this -

Two-piece iron rotors with aluminum hats for front and rear, and pads for front and rear as well.

I should have details and pricing later this week.

PSCB and PCCB are quite different beasts. PSCBs don't seem to be problem free - have they quietly been withdrawn on the current cars?

Schnave

Only available on the Taycan. Here’s why:

FWIW, I got iron brakes on my new Cayenne Turbo Hybrid (which is awesome, BTW), and they do rust from low use. In fact, I have not seen the rear rotor be fully shiny yet. It's not too ugly, but I can see how someone with less mountainous terrain could use brakes even less.

This thread took a turn into the confusing mixing in Carbon Ceramic (PCCB) vs Tungsten Carbide coated iron discs (PSCB).

PCCB's have been around a while, they can be re-furbished there are options. On the sports car you can get iron rotors and pads that fit the existing calipers. But this thread is to discuss PSCB on a Cayenne..

I'm only aware of Porsche and Audi that uses these rotors. The calipers are from Akebono, unlike Brembo which are used for the regular iron rotors. PSCB calipers are larger.
I think the disks are made by Bosch.
I'm not aware of any non-PSCB pads that fit the caliper, as a result you need to swap calipers. Any Cayenne caliper will work, base, S/GTS and PCCB.
I think Brembo BK-20 (8 piston) calipers are used in the front and are used across other Porsche cars, 991, and other makes, they might work.
Once you have your caliper, you can choose the matching rotor size and pads.

If what Scnhave said is true about the Taycan only having PSCB now, that is contrary to what I thought that Porsche discontinued them.
I don't have any experience with the updated PSCB rotors (part number ending in AF) but my understanding is that they coated the hub to reduce the squeal sound that humans can hear. Anyway, swapping to them out of pocket would cost more than new/used caliper and aftermarket iron discs and pads.

The Audi PSCB's are the similar priced to Porsche.

So, if anyone can find (prob doesn't exist), Tungsten Coated aftermarket iron rotors that fit the Cayenne, that would be good to know, but Porsche/VW prob has a patent on it.
