I noticed that my 2010 brake pedal was almost impossible to press but shortly found a broken vacuum line from the vacuum canister on the master cylinder. Perfect fit for a 14-20 bolt and it works fine. But after a thorough search I cannot find the other end of the line or pics or schematics of where the line terminated. I finally decided that something yanked the line off and it's out on the roadway. The check engine light is still on so it must be something Any idea where that line used to go?
