Check the flexible rubber brake hose at the rear axle. A common failure mode is when the rubber swells with age and squeezes off the lumen making a check valve out of the hose or just blocking it completely. It is very common for the rear cylinders to freeze up due to corrosion and they are usually too far gone to rebuild. Also, bleeding can be frustrating with that model master cylinder-vigorous, rapid pumping will often expel a trapped air bubble
