Decided to do as you advised in the end and go the tried-and-tested route, most scrappys closed up around here now so went further afield & scored a couple of Ka valves cheap as chips

True no need to buy new not much to go wrong is there! Ordered up a couple of standard-bore wheel cylinders too from thee bay so will get all done & bled same time. Great stuff
Ta again for your help bud

cheers
