Strange noise when stopping at low speed random


my car is Nissan Micra K12 1.0 petrol (2008). Rear drum brakes. I have this very strange loud noise when I'm stopping at low speeds 5-30km/h it happens randomly. I cannot diagnose the source of the noise, because it feels like it's everywhere, like some kind of vibration in the whole car.

I had the car to the service, but they told me the brakes are fine. I'm writing here hoping that this is some common problem to k12 micras and the solution is known.
