I noticed the other day that the pedal wouldn't come all the way up when I shift into Drive; I'd still have to use the handle to release it all the way. Yesterday, it stopped working completely and I have to use the handle to release the parking brake.

I'm going to check all the vacuum lines - they're white IIRC from what I read earlier - and make sure they hold a vacuum, which should be 34 kPa according to the service manual.

The manual also makes reference to 2A843 - "parking brake release control motor". There appears to be no reference to it in the parts catalog; is this part of the parking brake control pedal assembly?

Probably. Ford is traditionally pretty quiet about that whole system. Guess they never expected them to fail.

Never had a problem with it before, perhaps something is loose somewhere. I'm hoping it's a vacuum line issue more so than the pedal itself, because it's discontinued in a typical Ford fashion.

Have you found good illustrations of the system in the service manual? I think that would be step 1 to verify vacuum line integrity.
Maybe the pedal is bound up, weak return speak or something.

If your car is like a box, the vacuum motor is nothing more than a sliding rubber switch at the base of the steering column and a vacuum chamber (like on the hvac system) that pulls the release.

Plastic housing, with an inner rubber slider that opens or seals vaccuum port to direct vacuum to the chamber on the base of the steering column that gets manifold vaccum, a line from that runs to the vacuum chamber mounted on the parking brake assembly.

So it releases with the handle? I've never dealt with problems with Crown vic ones but with other makes the vacuum release either works or it doesn't. You could always try putting a vacuum pump on it and see how it works with that.
