Just donning the idiot hat here for a while.
So I swapped the front wheel to another frame with the result of it's functioning better (with rockhard brake blocks) there.
And switched the calipers to 105 with anyold softish pads & that's now working better on this frame.
Within time I'll marry up the wheelsets to match again - just now even the memory of how they were functioning seems a nightmare.
