So, while needing to remove the master cylinder to refurb it I took the opportunity to strip the entire side of the chassis in the engine bay down, refurb, treat some rust underneath the ABS pump and generally clean it up.
so, all going smoothly, rust treated, new drain hole created in the front section "dam'd off" by the ABS pump bracket (well worth looking at if you have one of these with ABS - water sits in the chassis rail between the front cross member and the ABS bracket), everything cleaned and polished, all rust treated, zinc's and seam sealer'd to look like new.
Put everything back together - brake pipes (a right pain getting the rubber separators and all 5 pipes back in the right order!), wiring loom all nicely clipped back in. ABS pump back in nicely after a general spruce up and new bolts, all the brake pipes on that end back in place, refurb'd master cylinder back in place and bolted in with new seals, all shiny and cleaned out.... first pipe back in no probs on the primary circuit, so only thing to do before bleeding the brakes is to connect the last, most easily accessible brake pipe to the second cylinder...... and it cross threaded.
So now, master cylinder back out and awaiting to see if I can get a tap to re-cut the thread. Even worse is that it looks very much like the problem was the seal between the brake booster and the cylinder so the refurb wasn't necessary either.
Sods law at it's best. Even if everything is shiny.
