Been working on my IH dump truck. Pulled the heads, and took to shop, back in a couple weeks. Then I get to finish hauling gravel about 100 yards, then gonna sell . Good ol' truck but down sizing. I have doon a ton of work, new tires, brakes, transmission, and now engine. I rebuilt the master cylinder, but cannot get my brakes to work. Have tried several methods, Mighty vac, and a helper pushing the brakes, and got no bubbles out of the system, so am sire that part is good. I did bench bleed the master, it is working good. This has a air assist, and know nothing about this. The brakes are the last thing to get this on the road, if anyone has an idea, lay it on me. Note: in the morning, or when the brakes havn't been pumped, there is resistance on the peddle, but it goes to the floor. Next push no or little resistance.
