This pic, (1) bleeder is unscrewed and there is a quick release of air then a sputter of fluid before a stream of fluid. (2) is the vent line I believe, when the brake pedal is pushed to the floor air is forced out from this brass fitting. We tried bleeding the brakes while the engine was off...

Step #9 in this manual is concerning, the air pack looks to be a brand new unit and we may need to replace it?

We have, but at each step there is still air in the lines. Not sure how we keep getting air into the system, there are no leaks.

Also, we have the technical manual and we unhooked the vent line on the air pack cylinder. Every time we press the brake pedal down there is zero resistance on the pedal itself and air will leak from the brass fitting. Is this common to have air release when the brake pedal is applied?

We did, the bleeder screw on top of the cylinder has compressed air coming out every time we unscrew it.

I have a AMC M35 and I’m pretty new to these trucks. We’re bleeding the brake lines at each wheel cylinder, keeping the reservoir filled after each one. Spent at least 45 minutes bleeding the system, but there’s no pressure at the pedal. The master cylinder and air pack are pretty new. Any ideas?
