Creaking noise when braking

[Chrisam4f83]

Need some help…

I have a 2017 BMW M4 F83. On hard braking, seems when the brakes heat up after a few minutes the rear drivers side is making a heavy horrendous creaking sound…

I took it to BMW and as suspected they said it needs new disks and pads. I’ve put genuine disks and pads on and instantly im getting the same noises again.

I’ve uploaded a couple of short videos of the noise on this link.

Thanks!
