Did you exchange all your fluid? Fluid can pick up moisture and will rust parts from the inside out. Did you grease the sliders and see that they move freely?
Did you properly seat the new pads?
when you pushed the caliper in did you push it all the way? you may have hit a rust spot on the piston.
put the back on stands tires off the ground. Remove ont tire and do the same test and verify you have sooth movement.

Did you adjust the rear break shoes before you installed the rear drum? Or did you just slide the drum on?

Ooh yah you have a yj... This a rear drum system. Besides adjusting the rear braks shoes did you check the drum or replace it?

On your frame there is a metering block that your brake lines go into, it can prevent fluid from reaching your brakes. There is a rubber boot or plug on the front or rear of the metering block (cant remember which) that hides a little pin that sticks out. You either have to push it in or pull it out ward ( again, cant remember). that will allow the fluid to reach your brakes. That pin could also prevent you from properly bleeding your brakes as well. I would check out that pin and rebleed your brakes and see if that was it. Good luck and hope this helps.

Your last post is a bit cryptic.
Your issue is with your rear brakes correct?
adjust your rear brakes before replacing any more parts.

Jack the rear of the vehicle and support on stands so both wheels are off the ground. From behind the rear wheel there are rubber plugs covering the adjustment wheel(see pic). Remove the plug and using a brake tool or flat screwdriver, adjust as normal feeling for drag while turning the tire. You want just a little bit of drag as the tire turns. Adjust the other side the same. Then go inside the Jeep and stand on the brake pedal one or two times to center the shoes in the drum and go check the drag again. You'll notice there isn't as much as there was just a second ago. Readjust the brakes and stand on the pedal again. You might have to do it 3 or 4 times but it's getting done right. Repeat the same thing on both sides and go see how much better the pedal feels after. And don't forget to recheck your fluid reservoir.

I called it the wrong thing, its the proportioning valve. The rubber cap on the right side of the valve shown is what I am talking about. It may or may not be part of your problem. I have had to reset the pin in the valve before for my brakes to work. Good luck
