good lord you've been through the wringer with this
I do sympathise as I've been there myself where every bolt is seized or snaps as you apply the spanner
PB blaster is prety good but it needs time to soak in and do its work
So I'd heat the joint up cherry red then cool it down with PB blaster and keep applying it until the joint is wet then leave it
the idea is to expand the joint with heat and then by cooling it with the PB blaster oil it will be drawn into the gaps by capillary action
also brake unions are amongst the worst to unsieze as the pipe is so thin its just twists and won't resist any torque as you try to undo
often in these cases you will have to replace the solid brake pipe with new
I would concentrate on getting that corner off the car so you can work on it on the bench as things are usually eaisier off the car as you can hold the part firmly in a vice to undo bolts and apply hammers, easiouts etc
so try once again to remove that brake hose joint where the flexi hose bolts to the solid pipe on the car
if you can't break this joint then I'd trace the brake line back to find the next join with the solid line and remove it there
if this is all frozen solid then I'd cut the solid line where it forms a straight line as this will allow you to get a pipe flaring tool onto it later and add a brake pipe union
do you still need help?
