Thank you for the offer of some machining Jeff...We have some bits of sheet shim at work for tweaking ageing woodwork machines, so I have that option if needed.
I have no plates of any kind between pad and calliper..Perhaps you have put your finger on the problem, or part of it. I just have piston to pad direct (with a bit of coppaslip.)
It certainly does look like the pads, or definately one pad has been "leading in". But curiously the locking effect that I suffered happens when the thick end of the wedge is leading (When rotated backwards).
I did clean up the actuating rod soon after I got the bike, as it had considerably corroded. I haven't re-checked it yet, but the lever action apears to be satisfactory and has the all important free play which I often check.
Still hoping that this is all down to something shag-witted that I've missed...Dammit I can't wait for the bits to arrive. I'm going to hoik it apart tonight...
