Okay, I've bled the brakes. My Westy Syncro still has a soggy brake
pedal. If I pump, it gets a little better, but not much. Sometimes I
hear a buzz, and it gets to be the best. If the engine is off, it
feels better, but with the engine running, it feels really mushy. A
friend suggested the brake booster might have a vacuum leak.

Don't believe I've seen this come up before. Master cylinder, yes, but
not the brake booster. I haven't yet looked in the bentley to see
what's involved. Half afraid the dash will have to come out.
