Gents........... I just bought a 2006 997.1 base Cab. (5th 911). I took out the air cleaner canister and cleaned it thoroughly. Upon replacement, I went to take it for a cursory test drive. For some reason, the power assist on the brakes ceased to work. I fancy myself as a very capable backyard mechanic who doesn't do stupid stuff. That may have changed?

I have been told that the Oil pump vacuum line part# 99711005503 could be the culprit. Anyone heard of such? Thanks
