Did a front brake job and used a great tool....

If you ever dread having to replace rotors on an older vehicle, because you know they are going to be stuck on...yes there are some tricks such as using the bolt and 2 nut tricks but I found a great tool made by OTC tools, that is a drum puller but it works well on rotors too...I sprayed penetrating oil in the lug holes and around the center bore, hooked up this tool, and with a couple of turns the rotor popped free! Even using the bolt trick on the rear which I did took me a while, this was like 2 min and its off. On the WK the rotors were original they were on all of 13 years and 110,000 miles. So I give this tool 5 stars!

of course I gave the hub and inner face of the rotor hat a coat of anti seize in case I ever have to take em off again.

I think no matter where you live if there is moisture in the air, cast iron/steel will rust. When you got a stuck rotor there are a few options...one is the brute force sledgehammer method but that is risky since it puts a lot of force on the bearings inside the hub. The other method that works is the bolt through the hole on the steering knuckle trick with 2 nuts on it, that can be used to push the rotor off (use one bolt with 2 nuts on it in each mount hole, put the old pad against the rotor to spread the force out. That is how I got the back ones off back in December, the rear mount is threaded so I just got longer bolts of the same thread, put a bolt on the end and then put the old pad against the rotor to spread out the force. The 2 bolt trick works without banging on it with a sledge but it takes longer as you have to rotate the rotor to apply the force in different spots on the rotor.

Here's how I removed the rear ones. No banging with big sledge, back off the star wheel for the parking brake all the way...get longer bolts with a nut...etc...just get it nice and tight, take a hammer and just tap, no banging needed after letting the penetrating oil soak in...

And before installing the rotor....coat both the hub....and the inner mating surface of the rotor with anti seize...and next time the rotors will literally slide off...
On our '98 ZJ I have been doing brake jobs on it since it was about 2 years old, I am up to about 4 brake jobs front and rear I think....and since I always used anti seize..the rotors have never been stuck on...

I just bang mine off with a large dead blow hammer and hearing protection. Worst case is you use a metal sledge and bend the rotor you are replacing anyways.

But what about the wheel bearings? I wonder how many people have had wheel bearing failure not long after banging off the rotors? BTW, since I had to do brake jobs on the '98 ZJ early on (the oe rotors on those never lasted, aftermarket was actually better) I always coated the hubs with anti seize. Never had to use a hammer once. And, the bearings on that Jeep have never had to be replaced...even at nearly 180,000 miles....just wondering about that.....
