Ain't that purty. Looks just like the one I installed on my one-ton. Sent in a unit from an old Cadillac for a core. According to a book I have, 70+% of the braking force is done by the hydrovac. I installed mine after my knee gave out when driving my rig with slide-in camper pulling two motorcycles on a trailer through Vancouver rush-hour traffic on the way out to Vernon BC. It's the same knee that I use to kick-start the motorcycles. Could there be a connection?
