You might just have crumbling vacuum lines like a lot of us experience with age and heat . . . or it might be a specific part. Check the cheap stuff first. I know that you've posted a good bit, so maybe you've replaced all of that tubing. If so, then are you still on the original brake booster? booster leak or bad check valve in the brake booster lines might give this symptom. The coolant bypass valve it more centered, but its solenoid and lines run over to the driver's side.
Hope you find it easily.
