Pedal should come right up vacuum or no. I suspect the fluid inside has gummed up & the leather piston seal is sticking to the sides of canister.
There may be some gum left after the complete fluid change and cleaning the reservoir. If there is some in there and where it might be causing trouble is hard to tell.
I was under the impression that the "piston seal" was separate from the canister, with the "power piston" operating inside the canister and not relying on the outer seal.
The pedal comes all the way up after braking. The brakes release immediately after foot pressure is off, but it takes a second or two for the pedal to reach the top of its travel.
The brakes do not fully apply until the pedal is pushed firmly until travel stops (which takes some muscle power) but the pedal is not "bottomed out" and there is no sponginess when the brakes are engaged. It's kind of a sudden transition from no-brakes to nearly full braking. Difficult, but not impossible to feather the brakes at a stop.
Remember, there's no vacuum at all in the system now. The brakes behave in pretty much the same way that I recall other power brakes work when the vacuum is gone in situations such as losing engine power.
I'm planning to keep fiddling with it in its non-power mode for a while. I haven't seen anything posted about using the brakes this way for any length of time, and wonder if it might help loosen up the
check compensator valve to do so. I do believe the check valve is probably the most likely culprit.
