annoying rattle from drivers door when I apply the brake

[Bluestaffy09]

Not sure where exactly on the door it's coming from could be the window  or something  loose  inside the door. It stops if I put pressure  on the door panel. It only makes a noise when the brakes pushed in.  Any ideas

I get a similar clunk like something hard hitting plastic, and wondered if its a chunk of seat mechanics clonking on the seat side panel ??

I get the clonk on acceleration/braking  & turning hard too...

Bloody annoying either way
