'52s method works best on a brake system that is totally dissasembled for major service.
In your case, just connect a clear hose to the bleeder screws. Put hose in mason jar to catch old fluid. Pump and add fluid to M/C until clear fluid comes out at each wheel.
Moisture in lines and lack of use will kill a brake system the quickest. I had rebuilt the rear brakes on my '54, and then it sat up. When I got her going again, the new wheel cyls were ruined from sitting.
good luck
