I agree. I'm currently getting my old 46 Coupe ready for some serious cruising this summer and noticed the brakes felt a little soft. I flushed the system with new DOT 3 fluid and the pedal is now nice and tight. There didn't appear to be any air in the system, but the fluid must have degraded with time.

I use a home built pressure bleeder for my under car MC. I have a couple of high points in the plumbing that make it difficult to bleed any other way.
