New SS brakelines mayhem

Putting new braided SD brakelines on up front on mykz1000 j3 83, whole system is sound and worked fine with the rubber lines, now its
it's impossible to get pressure on handlr. I have bled the system a zillion times in allthinksble ways and all the line seem full of brake fluid but no pressure on caliper. Please advice this desperate man.

Bleed it at the master cylinder a few times.

Tie wrap the break leaver closed over night, then with very very little movement about 1/8 of an inch or less, Take Your Time and get ALLthe little tiny bubbles out, then ty wrap again then repeat until you get a firm grip. make sure there are no backflow loops in your system tap the hoses with a wrench. Even lay your calipers on the ground

Just took lines apart and master cylinder too, it all looks good including piston/gaskets etc but
the weird thing is that if I take the master banjo off the liquid stays in the cylinder, won´t even be
pushed out with the handle. Does it need a pressurised system to work?
In that case only way is to either draw liquid down with a pump from bleeders or push it up bavkwards.

How do you guys fill an empty system?

Check if your MC tiny reservoir ports C and D are not blocked with any debris.

Will do that again properly with some air, also someone said the gaskets are prone to act up
and block the pumping worst case... maybe rebuild time...
