Have a hard pedal now as the brakes work fine in “manual” operation however. Guess the Delco Moraine booster has an internal leak and needs a rebuild or replacement. Any ideas on where to find one? Also wondered what is the usual failure mode?
2) Since I need to pull the booster now would be a good time to convert to a dual master cylinder & split the lines. Anyone have a source or part number? Planning to keep the drums at this time. Appreciate your help!

I have a similar problem, but the diaphram on my 61 bonny whistles until you hit the brakes. Brakes work OK, but I would like to do what you want to do. Can not find out what will replace the old booster. I would relly appreciate help here.
