Has anyone had the brake booster problem on Edges made prior to the 13N02 dates of the 2010 through 2012? I just took my 2008 Edge in because the pedal was mushy and it made a hissing noise (like air being let out of a tire), cause was confirmed to be the brake booster. Why is the 13N02 limited to only fords made through those years, was there a separate manufacturer of the booster during that time or something?
