...It's only taken me about a week on and off......letting my temper cool down and back in again giving it a ago. New seals on the calipers , new copper washes , new cylinder.......and hours of pumping the fu#king brake lever.........then out of no where BANG it starts to work even though i had the caliper nailed to the wall and the brake in the vice on the bench. 
So i'm getting there , took the lot down and set it up on the bike and it's still working BUT the big test is tomorrow as i'm going to have to take the brake hose off again to route it in properly and get it all set up again .....fingers crossed it shouldn't be to much bother..........famous last words ....
TOP TIP for anyome who's thinking of doing this themselves.............DON'T !!!
Pay someone else to do it and save yourself a massive massive headache..Kids and misses not talking to me but Life is starting to look good again ......
.........Still took me about another hour or so getting the air out after I fitted it properly but it's pretty much there. I'm working on the theory that once I start riding it a bit it will only get better !!!
