Caught on Video: PCCB Brake Noise!!
2024 C4 GTS with 400 miles. Brakes were bedded in. If this is what Porsche calls "normal brake noise to be expected", they can keep it. It sounds like a friggin' freight train and vibrates the whole interior. I don't care that they're PCCB "race" brakes.......How is this acceptable??
Doesn't do it all the time (I cringe every time I step on the brake waiting to see if it's gonna happen) and doesn't matter if it's hot or cold, but it's only under light pressure braking. And no, I shouldn't have to alter my driving habits to slam on the brakes at the last second (to increase brake pressure) to keep the noise away.

Pads/rotors were bedded as per the usual. Multiple hard slow downs from 40 MPH to warm things up, then multiple hard slow downs from 60 MPH followed by driving to let them cool down without a full complete stop that could create an imprint on the rotor. During the 60 MPH stops, I definitely got some smoke and smell so I know they were hot enough.
While I'm no brake expert, to me the sound seems to be more of a metallic sound than a sound from pad material on the rotor. It's not a squeal, but more of a vibrating groan if that makes sense.
