hydroboost?
I don't know if this will help or not but, I've got a hydro-boost system on my '04 Chevy Avalanche from the factory. I like it. I don't know why they put it on my gasser but, it's there.
I've also seen the system on a 2002 6.0L (Gas) Silverado 1500HD, and 6.6L Duramax pickups.
The hydro-boost system from GM uses the power steering pump to provide hydraulic brake assistance.
