Unavailable for a longer period with no satisfying alternatives.
So we had simply to make it ourselves, exactly what we did.
We made our own late model Bay window bus brake booster.
We guided the well willing factory through the project making exactly what we needed.
Designed with the correct right-angle 14mm hose connection at the front,
and an angled vacuum connection at the rear.
The perfect replacement with a price tag you will like even more
This is a proud BBT production.
