What do you mean by "the top piston won't tighten down"?

I'm sorry, but i don't understand what you're trying to say.

Did you bleed anything?

I think he means the top bolt that holds the caliper on I had the same problem on my last axlel and I had to go get a bolt that was a quarter inch longer to get the threads to catch.

Yes the top bolt, it came with two bolts one for the top n bottom. I did bleed it out first. for sum reason it just wont catch the thread, i try screwing it in without the caliper n it catches fine, so a longer bolt will be it?

Got a C-Clamp or something you can try to pull it all together so you can get that bolt in?

I must ask, are you driving your jeep around with one bolt holding the caliper on?

So why doesn't the bolt screw in? Is there no thread left on the bolt? Is it just really tight? Any clue?

Its a new bolt, im thinking the receiving end has the thread issue. the problem is it goes somewhat tight then it goes completely loose, it will keep repeating that process

on mine the problem was the bracket on the knuckle had some boogered up threads. so I needed a bolt that was 1/2 longer to catch threads. if I remember correctly 1/2 inch longer was a hair to long so a few spacer washers helped.

best of luck

you need to loosen the bottom bolt and try again. but it sounds like the bolt is not going in straight like it should that is why you get the feeling like its tightening and then bam its loose again.

and the pressure problem wont be fixed by fixing the bolt bleed the brakes in this order back passenger back driver front passenger front driver two people one in the cab one operating the bleed valve on the wheel fill the reservoir after each wheel. I had to do mine twice after by disc brake conversion but its much better now

Loosen the bottom bolt. Try to start both bolts at the same time and tighten them together.

If that doesn't work you might need to drill out the threads and heli-coil it.

You can't just bleed one brake because there will be air in the system.
