Bad brake booster, no really.....

I had the booster fail on me when my vaccuum pump (2000 9-3 base auto) seals wore out and let oil into the booster. Well the way I found the problem was that I was noticing a shimmy at highway speeds, but it was random. Would come and go.
Turned out that the booster was sticking and the brakes were dragging slightly. The front right rotor was overheating and warping causing the shimmy. Pulling up on the pedal with my toe made the shimmy go away in a minute or so as the rotor cooled down. Replaced the pump and booster and all is well.
Just a thought.....YMMV...
