TJ brake problems

I have a 2004 Jeep Rubicon that was pulling hard to the left when appying the brakes. I purchased new brake pads, for all four wheels. After removing the front wheels I found that the right front caliper was stuck and the pads completly worn off. After failing to repair the caliper, I bought a new one along with a new rotor. Replaced them both, bled the brakes and am still having trouble with the caliper sticking. Any ides as to what is causing the right front caliper to stick like that?

If the right caliper was the one with the problem and worn down so bad why was it pulling hard left, wouldn't that mean that the left one is grabbing not the right, Just wondering?

I would replace the other side. It's kind of an unwritten mechanics rule to change both sides at the same time to maintain drivability. Now with the being said I have a 04 rubicon too and it has always pulled a little to the right when I brake hard just not enough to spend a bunch of money or cause a wreck.

Yep if it's pulling left from a stuck brake caliper, that would be from the left caliper, not the right caliper.

Edit: Brain fart, it's the other way around. A stuck left caliper would cause it to pull to the right.

No it would b the right. If it's pulling left that mean the left side is working more. Did you lube the guide rails on the calipers? They could be sticking. As well as like I said before change the other side too.

You are absolutely right, brain fart on my part there.

I had the same problem with my 99 TJ. The stuck caliper episode was from time to time and not always present. After some time I decided to change both calipers since they are fairly cheap, $22.50 at Auto Zone. Well, It happens that both "new" calipers were also stuck. I went back to the old calipers and after bleeding there was no pressure from the pump. I ended buying a new pump and using the old calipers. It solve the problem completely. For some reason the problem was not the left caliper but the pump. Conclusion, since the front lines are one for left and one for right, it was the left circuit that was clogged and not the caliper.
Just my experience, hope this help.

UPDATE: I appreciate all the input guys, after replacing the right front rotor, caliper, all four brake pads it ended up that the right front felxible brake line that connects the hard brake line to the right front caliper was not alowing brake fluid to pass through it. I picked up a new one at advanced auto rebled the brakes and it seems to be working just fine. The reason it was pulling hard left was because after the right front caliper stuck open the pads were literally gone so the only pads working in the front were the front left thus it pulled left. Anyway thanks again for the help I hope this helps another TJ owner if they run into the same problem.
