You can _think_ what you want, but what really was happening was that the
Cruise was turned off while the brakes were applied, but then went to Resume
Mode as soon as the brakes were released. It had nothing to do with the
vacuum control, and everything to do with the electronics -- specifically
the brake light switch -- that turned the system off and back on. I guess I
just said the same thing as you said, but I don't care why it did what it
did, I only care that the symptom was electronic in nature not mechanically
caused by mats or binding pedal springs.

All Cruise Control systems will shut off if the brakes, or the clutch, are
applied. The Cruise system should remain off until the driver physically
presses the Resume button, or regains speed and presses the Set button. My
car -- in the failure mode -- would Resume as soon as the brakes were
released, and it didn't wait for me to press Resume or regain speed and
press Set. If I slowed to a speed below the minimum threshold -- 30-ish --
then the system would not Resume on its own because the system would drop
out altogether, as it should in that condition.

There is a new Toyota factory building in Blue Springs, (near Tupelo)
Mississippi which was recently built, but that factory building is empty
because of the economy situation.Maybe someday if America's economy gets
better, if Toyota's situation gets better too, Toyota might start
building some Toyota Prius cars there.
