I've seen hydraulic power brakes on Chevy diesel pickups too. I'd bet they were used on a lot of GM diesel vehicles.

If you are also running power steering the same pump can provide power to both.

I think my gas powered motorhome has the same kind of setup, except it was designed to handle a 12,000 pound load. Its too dark and wet out there to go look right now.

It's true. I really don't do anything but browse the Internet looking for trouble...
