make sure you didn't inadvertently disconnect your vacuum line that runs to the brake booster. It's also possible it cracked when you were moving stuff around.

+1 on the disconnected/cracked line, would be obvious vacuum leak in the engine bay...also random thought would be hard but if you accidentally plugged that hole would also cause issue

It could also be the in-line anti-backflow valve installed backwards.
