Brake fluid?

Forgot about that rare problem: Once in a great while you'll find a master cylinder with a bad rear seal, combined with a vacuum brake booster with an equally bad front seal. The result is the large vacuum hose running from the booster to the intake sucks the brake fluid residue into the intake and burns it. Saw that happen once in 30 years but it was a wild one to diagnose!
