Hey there Guest!
Let me start from the begining. Previous owner said he replaced Master Cylinder, Front and Rear Shoes, Front and Rear Wheel cylinders. Said he couldn't get a brake pedal. I discovered metal lines going to rear cylinders were on top (bleeder on bottom) I corrected that, then discovered Drivers front was missing the metal line connecting both cylinders. Replaced missing brake line. Then I discovered that he had put both top shoes on driver rear and both bottom shoes on Passenger side. And in order to get the pass. side drum on he shoved the adjuster over in a corner.
That's what I guessed but couldn't be sure. Typically, pumping the pedal won't help with air in the system. You will still have a spongy pedal. And I still think a hard pedal that slowly leaks down (10 seconds) indicates a leak somewhere in the system, either internal or external. I can think of some exotic circumstances but probably not worthy of mention.
Your PO needed supervision.
Common sense isn't very common anymore.
