I'm curious why you got rid of the PSCB brakes? Was it an issue with brake feel, or something else? I had PSCB on my previous car (a Macan Turbo), and aside from the non-linear braking requiring some adjustment, I really liked them and they seemed like they were going to last the life of the car. That seems to be the intention of PSCB and PCCB... that they are intended to be 100k+ miles before replacement.

I think Porsche/VAG used WVA number instead of FMSI number. WVA is the European standard. If you can find the WVA number you can cross reference the pads.

As far as I can tell 2025 Porsche Cayenne GTS without PCCB uses WVA 25007 or FMSI 1349 front pad and the rear is WVA 25143 or D1655, So if you search for those pad specs you should find a compatible pad. There a lots to choose from in low dusting.

So the one's that @3Series referenced should work.

In any event the brake dust is atrocious on the OEM pads. Hoping to find ceramic pads sooner than later as to avoid having to turn the rotors as well.
Don't rack your brains on this.
Buy the Dynamic Friction pads that I mentioned above.
99% sure they will fit a 2025 vs 2022. If they don't you can return the pads and if you have a mechanic, it'll prob cost you $200 to put the old pads back on and start from square one. Just start with the front corner.

According to Sunset, 2019-2025 have the same pads for the rear. https://www.sunsetporscheparts.com/o...ds-9y0698451aa
Search for the front, calipers rarely change from Brembo.

Squeal and brake feel. I probably would have gotten used to the brake feel but the squeal was horrendous.
I know Porsche has updated PSCB rotors and pads but I would have had to pay out of pocket and it was less expensive to ditch them.
The no brake dust was nice, but I have gunmetal wheels and honestly I don't really care if I have brake dust on my wheels but that's because I have Ceramic pads and its not too bad.
I used to have a 958 Cayenne with silver wheels that I swapped to ceramic pads because of the brake dust so I guess I care a little bit.

FromAI:

What the FMSI System Does:
  • Standardized Part Numbers:
    FMSI created a unique numbering system to classify and identify different brake pads.
  • Common Language:
    The FMSI number provides a consistent, universal way for the industry to refer to specific brake pad applications.
All I could find was this:
https://sbparts.jp/catalogue/51571861/
I did a google search and this came back...

Standard brakes
For a 2025 Porsche Cayenne GTS with standard steel brakes, the front and rear FMSI numbers are likely to be:
  • Front: D1686
  • Rear: D1820

I have cross referenced the 2025 Porsche Cayenne GTS with the standard GTS red brakes and they are definitely front FMSI D1349 and rear FMSI D1655
The OE Porsche numbers on the Sunset Porsche site list fronts as 9Y0-698-151BE and rear 9Y0-698-541AF
Cross reference these on the Brembo site front - https://www.bremboparts.com/africa/e...e/pad/P_65_049
Rear- https://www.bremboparts.com/africa/e...e/pad/P_65_042
Cross referenced these pads on the Porterfield site - https://porterfield-brakes.com/product/ap1349/ , The shape and dimensions are the same.
Rear- https://porterfield-brakes.com/product/ap1655/

There are a couple of variations of the pads from Porsche with different letters after the part number such as AF, BE,AE AD. I don't know what they mean, maybe revisions or internal references. Just the thickness may vary by a mm or two but are still considered in spec.

"The FMSI D1349 designation describes a front brake pad for various SUVs and trucks, including the Porsche Cayenne and VW Touareg, with dimensions around 209.5mm wide, 94.7mm high, and ~16mm thick, and it's used with various friction materials"

The difference between the Brembo OE pad and the FMSI equivalent seem to be the bevelling on the backside on the backing plate on the Brembo pad and not on the FMSI spec pad.

I only have limited experience with PSCB's, one month on a Coupe that has 40,000km on it. There is only ever brake squeel on initial reverse out of garage......then no more. I wonder if I have the updated PSCB's ? and how would I know ???

I had PSCBs on my previous vehicle -- 2020 Macan Turbo. It definitely took me a while to get used to the initial bite, and then lack of linearity thereafter. But once I got used to that, I really liked them. As far as squealing, I had that too, although it was generally minor. I found that washing the rotors (as best I could) as part of my general washing routine helped tremendously. Sounds silly, but it worked for me. Obviously I was only washing one side and only what I could easily access, but it made the squealing resolve for a week or more each time I did it.

I also had my Porsche dealer tell me that the squealing happens more when the vehicle is being driven too gently. I drove it a bit harder the longer I owned it (still respectfully though), and I found that the brakes stopped squealing. Take that for what it's worth, but sometimes a good Italian tune-up goes a long way!

Is that photo front or rear? Those rotors and calipers look quite different from mine. I was hoping to make a switch on mine as well, but I might be searching for different pads. 2025 Turbo eHybrid here.

What year is your Cayenne? and which model? We are all having difficulty finding the ceramic pads. Thanks,
