Gassers use manifold vacuum. I believe your Engine has a similar butterfly valve that creates manifold vacuum used for the Pneumatic Governor. That could also be used with the power brake booster if the manifold vacuum is high enough.
It is also possible that that Engine did not come with the Car. The pictures in my book are from 190Ds. Did 190Ds have power brakes?
