Probably would help if you add a video of the noise.

Sounds like brake pad slap. Can you describe it further?

I currently have something very similar! For me, there's a weird clicking noise whenever I'm braking or slowly moving. I had it checked out by the dealer and they told me a that a bushing on one of the control arms is damaged. Maybe you could possibly have the same issue.

I'm getting it repaired under warranty so I'm not too sure how much this would run you if you happen to be out of warranty.

I hope this helps!
