Can’t really see from that pic. Is the other side the same?
I once had a similar issue of loud grinding noise and turned out to be a stone (from gravel track) caught between the disc and the shield / back of disc protector.
It is the same yes. I took the car out again and no noise which is odd as was expecting something.
The only thing that seems to stand out is all the corrosion on the disk.
I would personally just go do some heavy braking to clean it up.
Had a similar thing on the girlfriends' 2021 Audi and Audi Assist came out. The guy went up and down the road a few times and kept pressing the handbrake button. He even told me to do it if it happens again, so it must be very common.
Yeah I hadn't taken the car out since Xmas Eve when taking that picture. Just took it out today.
Why I first drive my GTI after a wet run and then not drive for a couple of days, you can ‘feel’ the disks cleaning on the pads, only for a few hundred yards. Handbrake also releases with a right crack on first use under the above circumstances.
I get that crack on first use as well from time to time. Just sounds like things stiffen up after being sat for a while.
Update: Just took the car out earlier for the first time and no noise at all now which I was not expecting! When I last drove the car Christmas Eve you honestly would have thought the exhaust was trailing the ground, then that noise stopped and all you could here was like someone was using a grinder only it was coming from the back of the car. Parked it home thinking it'd definitely need transported to garage but now the noise has completely gone (shrugs)
