What is this "Hydroboost" I see mentioned in regards to Brakes?

I did a search in this section but did not produce anything.....maybe I misspelled it.
Someone please enlighten me....:huh:

GM discovered (?) that some cars didn't have enough vacuum to run all the HVAC and the brakes so they built/found a hydraulic gizmo that uses pressure from the power steering pump to power the brakes. Thye use it on the diesel stuff that has no vacuum too.

The hydroboost can be found on diesel trucks and vans from the early 80's well into the 90's.
It is a very compact unit, gives lots of valve cover clearance, fits our existing firewalls with very little work.
Basically a linkage change.
SOME of our master cylinders bolt right up and others need a slightly longer rod.
'Compared to a vacuum unit they are extremely strong.
Cheap too at a wrecking yard

It was actually for diesels, diesels don't have a throttle valve and therefore no manifold vacuum.
