master cylinder only half working 1800 1972

Not that it would affect the bleeding, but it is recommended to remove the brake warning switch in the distribution block that the 2 brake lines from the master cylinder go directly to. If you don't removed the switch, you can damage the switch while bleeding the brakes.

There are brake pressure limiters(proportioning valves) for the 2 rear calipers mounted under the car and the 2 brake flex lines screw directly into them.

The proportioning valves can be stuck or clogged and/or the rear brake hoses could be bad, both of which can cause bleeding problems.
