After restoring all four calipers, no brake fluid comes through at front calipers. What could be the problem? Faulty master cylinder or what else?
I am trying my best to get this early xjs (car no 30 RHD) back on the road, but it tends to have negative effect on mental health at times..

 

Welcome to the Forums.

Not sure where "SE" is in the world.

I would be cracking the pipe nuts AT the master cylinder, and confirming fluid is actually leaving the cylinder. That will eliminate/condemn the master cylinder.

I would hedge towards the master cylinder.

When the best is sorted, please do an Intro in the New Members Area.

 

I pressed brake pedal many more times than expected, and the brakefluid eventually came through.
SE stands for Sweden😁

 

Well done, air is a mongrel to move sometimes.

Got the Location now., thanks.

 

Best to "Bench Bleed". Even though it's called bench bleeding it can be done on the car. Here in 'Merica there are Dorman Kits for this with a variety of fittings and 2 hose lengths that costs about 10$. I'm not fan of plastic and rubber so I have a variety of old steel brake line fittings with the right ends and short lengths of steel line that accomplishes the same thing.



Very hard getting air to defy the laws of physics and bench bleeding helps. This helps too. I've tried every bleeder known to man, 2 Man, vacuum, gravity but the check valve style shown below is the fastest, cheapest and most effective way to get a rock hard pedal. You do need to neatly coat the bleeder threads in teflon tape, clamp on the hose and stick the output side in a tight hole in cap of a used water bottle. A few pumps until no more air, tighten up the bleeder and job done.

 

isca , where is that check valve available , Dorman or who?
a great idea?
