Finally got around to replacing the gearbox and drive shafts and thought i must bleed the brakes too before heading out for a test drive as they where non existent.
So when i tried to bleed them nothing would happen on the rear right!
I tried the other corners and they where full of air but you could get fluid flowing.
I tried with a vacume pressure bleeder and the 2-man method and you can get some brake fluid with the 2-man method but it doesn't push through. Also noticed bubble coming through the master cylinder when you release the pedal.
I'm assuming master cylinder/booster are stuffed as the car was off the road for a long time.
Any ideas?

loosen the two bolts that hold the master to the booster and see if fluid spills out/is inside the booster. that will give you an idea if it's getting past the master cylinder. could be a rusted up wheel cylinder on the rear right, can you move the two little pistons on it or are they rusted in place
