With a new non return valve,
aka pressure retaining valve
at the end of the master cylinder
bleeding will be a piece of cake Dody thumbs up

With a bit of luck you won't need
someone to press the brake pedal
while you open and close the nipple.

If you kneel at the side of the
car and lean in to press the
pedal by hand you can keep an
eye of fluid level, and top as needed smiling smiley

Loosen the banjo, or one of the
pipes that go into the banjo, try
pumping fluid through the loose joint Dody :

If you can, tighten the joint and try again.

In theory, you should prime the
master cylinder before you fit it.

Loosening the banjo, or a
pipe usually works the oracle.

May the force be with you smiling smiley

Please state exactly the steps you have taken in order to bleed the system. The basic steps are to have all bleeders closed, pump the pedal and hold, open one bleeder, close that bleeder, and then release the pedal. A pressure bleed applies a small amount of air pressure to the reservoir which will push the fluid and air out an open bleeder. A vacuum bleed literally sucks the fluid and air out a bleeder. Other one man operations include a tube attached to a bleeder with the other end submerged in a container of fluid so that fluid and air will come out but only fluid will go back in. Check valves built into the bleeder is another device that duplicates the hose into a container approach. Either method must be repeated at each bleeder. Typically, you start with the bleeder that has the longest line from the master cylinder such as the passenger side rear and work you way closer although doing both sides of the rear axle can be done before moving to the front or start in the front (passenger side) and then move to the rear. The volume of the master cylinder is so much larger than the brake tubing so that one stroke can push a few feet of fluid through the lines. With that in mind a smooth full stroke may be better than rapid pumping.

There is no need to prime the master cylinder. The reservoir gravity feeds the cylinder and a full stroke will push all the air out. If only the master cylinder had been worked on then cracking the banjo can bleed most of the air but you still should bleed the front and rear.

The fault at the master cylinder that will cause the pedal to go to the floor is if the primary seal is leaking over most of the stroke and the fluid simply flows around the seal and back into the reservoir. If you did not replace the master cylinder seals and the bore is smooth, they you need to repair or replace.

Another thought for you Dody.

If you get a hyperdernic syriinge,
you could use it to either suck air
out of the master cylinder, or inject
fluid into the master cylinder through
one of the holes between reservoir and master cylinder.

Unfortunately it's tough to diagnose via a forum. There must be air in the system or something is out of adjustment.

If it was good 60 years ago, does that mean it can't be improved?

I've just read your post again Dody.

When you bled your system,did you
get brake fluid out of each bleed nipple confused smiley
