If it was stored in a dry space where rust did not form all over everything, you could pull each drum, make sure the contact points on the plate are greased, as well as certain pivot points. Examine all the hoses for checking, and the lines for rust. Then install the drums, adjust the front bearings, and thoroughly bleed the brakes.
If there is any doubt about any line, hose, or cylinder, replace it.
Amateur restorer. Well, sometimes I have been paid for it. But not right now.
