HH,

When the MC was detached from inside the car and the cover removed, the only part accessible was the vacuum hose, so the inside of the canister has not been checked. There is, presumably, vacuum inside the cannister that could leak around the leather seal that surrounds this plate, or are you referring to the seal around the plunger itself? If there is gum in the seal around the plunger or actuator rod, then yes, I could see how that would restrict pedal movement and slow down pedal return after braking.

If these sealing problems are typical of a car that has not been used regularly, is putting them to use going to be helpful, harmful, or have no effect either way.
This isn't a particularly "old" BTC in terms of usage, with only 80K on the car, but that might not make any difference how much the parts have suffered from lack of use.

The issue of the reservoir "cover gasket," and how it effects the operation of the compensator valve seems to be a key that could make or break the whole operation of the unit. Is there any way to remove the reservoir cover while the MC is in place, make sure the port for the compensator valve is clear of gasket material, and maybe even check the operation of the valve?

I have a feeling the gasket is fine, but not so sure about the valve... and I don't want to go wrecking the gasket if its not the problem. I imaginge the gasket will stay adhered to the cover if I remove the cover.
