brake pedal vibs

I have 2006 D/A and I was wondering if anyone is experiencing this. When stopped in gear I get a buzzing type sensation from the brake pedal. This does not occur all the time but it really bugs me.

Check for vacuum leak from brake booster. Check all your vaccuum lines coming from brake booster.

I don't think it is the anti lock because it will do it even after a smooth slow stop. I thought it might be a line from the power steering pump rubbing something near the brake booster because the previous owner put rubber hose around the line.
Thanks for the help and I'll keep looking.
