I've noticed that the PCCB's make a woosh like sound when their first used in the morning (audio in video).

The sound in the video is a consistent whoosh, but sometimes it sounds more like a cyclical whoosh/scrape sound. The brakes (rotors, pads, etc) have been checked and look fine. Braking doesn't work well during this phase, but sound goes away as they warm.

What is the cause of this sound?

Thank you!

My PCCB’s have always been noisy, rears I think. Perhaps lake of sound proofing and so kinda thought this was normal? I am on 3,000 miles and they still make quite a loud rubbing noise when braking. My previous RS (991.2) had steels and they squealed so so bad so definatly prefer PCCB’s 😆😆

First drive after I wash the car I swear I did something to ruin them.

last time I took the car in for a service, when I drove it out of the dealership I thought they had switched the PCCB for rusty steel rotors it was so loud!
