I had similar problems a few weeks back ,not on a cherokee but a wagoneer. Are you running disc front and drum rear or disc/disc ? And did you bleed the master cylinder?

Fill up the bowl and run tubing from the brake ports back into the bowl and push the plunger in 10 to 15 times.

Look into "bench bleeding" the master cylinder.

probably lucky you had any brakes at all. I put my hydroboost and master together when I was building my buggy and got excited when I got close to finishing and forgot to put the rod in mine. Was a real head scratcher there for a bit.
