Adjust you're brakes with the adjusters. Jack up one wheel or set of wheels just off the ground. When you get a slight drag while spinning the wheels, try bleeding them again. When I did mine, they where a bit spongy and I felt as though I needed to double pump them to make sure I had enough brake. They got better after some use. Adjust them and drive the truck slowly around in the yard and then readjust the adjusters. Make sure there is a little drag on the drums. It worked for me. By the way, I bypassed my Hydrovac for the time being till I can get it rebuilt. I don't know if that will make for a different outcome for ya.
