Hi Rod
Yes at times the search feature on the MLU Forum is not that productive. So when that happens I do a google web search on MLU which generally yields more results.
Try this one Brake Booster should yield 119 results with either word Brake or Booster or both.

If you google advanced search on just "Brake Booster" you get 133 hits. Of course it gives you every time somebody typed Brake Booster no mater what truck they are talking about.

Problem with doing online search is they have dumb down the advance search on some "smart" phones and tablets, I can only do an advanced search on my desk top computer.
