The pad nearest the piston is the culprit as the video shows, the outer pad is a nice tight fit.
Any suggestions welcome.
Thanks

Then I use a product called Disk brake quiet.

I apply it to the Fingers on the Caliper and to the steel circular part of the piston lip.
The issue that I see or hear is that your piston is retracting too much. I usually don't have any appreciable movement in the piston. So I would wonder why that is happening, which suggests that your rear wheel cylinder on the opposite side may be leaking, and or you have excessive play in the rotor (is the screw installed, and are your lugs tight? Then I would suspect hub or wheel bearing wear. That much play isn't normal.
But then again the piston is supposed to retract when you take your foot off the brake so it is most likely chatter as a little bit of clearance can make a whole lot of noise….. then again too much clearance is saying that there are other things possibly at work to cause it.
Are you sure that your brake booster to MC seal is good, and that you aren't leaking any brake fluid in to the booster as it is being pulled out of the booster while it is under vacuum?
That Disk Brake goo, is good stuff and it keeps the pad firmly against the piston. A little goes a long way.
If you are sure about the other stuff, then apply a little of that goo, I have been using it for years on everything I have ever owned, it keeps the squeals, and clatter to a minimum….

Checked with the other side and its the same - inner shoe moves up and down by about 1-2mm.
Rear cyliders are new with no leaks and bearings done a month ago.
I think I'll try putting a bead of Tiger seal on the back of the pad to bond it to the sliding caliper and also a bit on the other pad to bond it to the piston when the pads are sitting on the caliper so there is a bit of flexibility on the pad when braking and keeping the pad floating.
Any thoughts?

Yes, I have a thought, I am thinking you are mistaken about the anti-rattle clips.

Brake Anti-Rattle clip how to. | VW Vortex - Volkswagen Forum
If you add those that are missing number 8 int he parts breakdown, need the upper and lower the other side uses the same springs but backwards as the upper left is the bottom right and lower left is upper right.
And a little dab of goo, you won't be rattling at all.

Now comes what looks like the fiddley part with the fitting so fingers crossed i'll be rattle free.
Will keep you posted and thanks again.

These springs are very thin and do not return to their original shape if bent slighty which was a bit disappointing as it seems they are not putting enough tension on the pad lugs.
Took her out for a test drive and it seems to have cured the rattle mostly but a firmer spring would of been better.
I've put a pic up so if anyone can confirm they are fitted correct then that would give me peace of mind.
Thanks again.
