Posted in the thread about disc rollers initially ...

Don't think that is the problem. Then thought the discs are perhaps warped.  Stripped the front wheel this pm:

Discs measure about 5mm, and no wobble - also sit nice & flush on the wheel rim mounts. Everything else appears to be fine with the discs.

Brake pads - looks ok I think. Shouldn't there be a spring holding the 2 pads apart?

Where do I look next to find the source of the shudder?
