It does sound like you have air in the system. If you get all the air out and you still have to pump to get a good pedal you may have to install a residual pressure valve. They are used to keep the caliper close to the rotor with out it dragging. You use 2psi on disc and 10psi on drum set ups. Residual brake valve
On my rig I run a booster off of a Chevy Astro van. So I went with a '77 model Corvette master cylinder. A Ford M/C has a wider bolt mounting pattern. Otherwise I would have reused the F250 "camper special" that I used on my manual 4 wheel disc set up.
