Please help! weird noise coming from the back while slowing down/breaking

Hey guys! How are you?
I searched all the forum about this but non of the threads relative to noises coming from the back sounded like mine.

At low speeds, slowing down i get this hard knock sound (and feel) coming from the rear left wheel (or breaking pads, or break disks or suspension, i don't know)

I stopped the car and tried to move the wheel to reproduce the sound but no luck.

When i'm fully stopped and i start rolling, the car never does the sound. Only breaking

Here are some videos

0:06 and 0:22


0:04 and 0:06


Sometimes is really bad


Thank you in advance!


UPDATE: SOLVED. Rear strut bolts needed to be tighted

How many miles on the car? Could be a rear strut mount or diff bushings? I'd get under the car or get it to a shop asap.

UPDATE:
Yes, it's done! turns out all this noises can (potentialy) be solved with a check in all the bolts under the car in strut bars, etc. Its done and solved.
