We had a couple of bottles of fluid left after our last attempt & a bit of spare time yesterday afternoon so I thought we'd have another crack.
With every sharp pump a little squirt of air seemed to be coming out of the rears but the pedal never got any better.
As we were about 1/2 way through the last bottle more air than usual was coming out but in our anticipation of success like the dwarves in Lord of the Rings we dug too deep for too long & emptied the reservoir :)
Might be best to start completely from scratch any way as I think we'll put in a remote power brake doodad.
I'll be sending some emails today to get some quotes.
:D
