Noise when driving over speed bumps with light braking applied

[Itsrelfy]

Hi all I got an odd noise when I drive over speed bumps with the brakes lightly applied. If I go over the same bump with no brake applied there is no noise. Also makes the same noise on uneven road surfaces when brakes applied 

 

Link to the video if anyone wants to watch and listen. Excuse the dirty floor mat!!! I'd appreciate any thoughts.

On my phone that sounds like more of a rumble than a creak but it could be my audio/ability to hear it properly. 
rumble most likely top mounts on front struts. 
creaks either bottom bushes or anti roll bar.

I'd say it was more of a creak really. Just confused why it's only with the brakes applied. Could be anti roll bar. Was told service before last it was beginning to corrode but it wasn't mentioned this time round.
