Done the outside one then I noticed inside one, didn't notice as I put it on as I got it all with bracket etc so just bolted it all on.
So yes I bled the outside one then onto the inner one, kept topping up fluid in reservoir and was getting fluid through both nipples, couldn't see any air bubbles so I gave it a try, nothing
So I stripped out the pads and checked pistons were moving, all good there and clean.
I'm at a total loss as to what's up.
I'm in Glasgow so couldn't get to Leeds but appreciate the offer.
