as in that is some type of corrosion from sitting? Or is that abnormal wear?

Thanks

need closer detail pics but almost looks like glazing, not seeing wear indicator or anything very odd

How thick are the pads? I was told to replace at 1/2 thickness. I bet you could scrub some that oxidation/rust off with a few aggressive passes. Beyond that you could bring to Porsche and I’m told they have a tool to measure.

From the picture, it sure looks like it. The PCCBs have an extremely long service life compared to metal. Your mileage would suggest you have a long way to go before thinking about replacing them.

Macster, thanks for posting the PDFs. Great reading. I especially liked learning that what I thought was taking it easy on my brakes near the end of a track session was actually producing more heat than how a pro uses the brakes. Something I need to work on.

Those are gen 1 pccb's. Does it feel rough? If so it's delimitation. its common in gen1 rotors.

Gotta love spell check...I believe he meant delamination. I don’t see any bad cracks between the vent holes but make sure you use the guide rod(s) when removing or installing wheels or you could make an expensive mistake if you nick a rotor.
