Re: Treadle vac disassembly snag

I hadn't tried a rocking motion so thought I'd give that a go, but in a different way than suggested. Rather than trying to grab the casting, I took a large rubber mallet and tapped around the protruding casting around the pedal shaft. I alternated that with some prying and twisting and banging it outward with the help of the internal spring. Via the vacuum line holes as reference I could see the power piston was ever so slightly coming farther out. The rocking motion had helped break it free but it was still tight separating from the brake piston.
Eventually, success. Here's a picture of it just as it came out. There's some white, chalky casting corrosion in the socket. Some of the goo at the bottom is due to the PB Blaster but there's debris with perhaps a little crystalized brake fluid mixed in. It could be worse. The bore looks fine.
I should mention this car lived it's life in the wet Western Oregon where all pot metal castings have rather short life.
Onward... thanks for the help.
