Hey Geo,
Sometimes we look to hard and miss the obvious. I had the same experience
after my restoration. The brake pedal seemed mushy the first try.
Afterwards it felt fine, at least for another few miles.
Someone told me it was air in the line. Another suggested it was the DOT5
fluid, so I painstakingly bleeded the lines making sure I didn't agitate
the fluid.
It turned out that the rear brake drums weren't adjusted correctly. I reset
those and now it's rock solid. Back to the basics.
Good luck,
John in San Diego
