Interesting. I have never checked vacuum under those conditions.
Does the vacuum eventually recover while your foot is on the brake or does it remain zero until you release the break? Just trying to determine if it's a temporary surge or vac drop with diaphragm volume change or an actual leak being exposed when the pedal is depressed.
If temporary it might be normal. I guess I can try the same test on my car when I return home next week.
