Just a thought fellow Vanagoneers.

Whilst doing some cleaning in the engine bay of my Van I noticed that the
rubber grommet surrounding the booster brake hose through the fire wall was
missing.  Sure enough the hose had started to rub and wear.  Just got to it
in time.

Moral of this story.  Clean your engine and you will see these missing
grommets.

PS  Can a leaking booster hose effect pedal pressure.
