Hello everyone. New to the forums and also to the Jeep world. This site has been very helpful and has helped me cure a lot of problems I've had since I bought my XJ. Here is a current pic so you all see what I have.

I need to replace my calipers because they locked up twice on me in the last month, so I am deciding on swapping out rotors, pads, and calipers. When I went to Advanced they ask me what size rotors and if which caliper. Apparently, there are two sizes/kinds????? I haven't read anything on this but hopefully someone can clear this up for me.
Thanks !

 

You just have to measure the rotors......

 

First off.. Welcome.
Second, I bought new calipers from NAPA & there wasn't any question. Were they talking about a WJ vs an XJ. The WJ has larger rotors and calipers. That's all I can think of.

Jeep looks good Black on Black, I've got the same look goin' What's your location?

 

in 99/00 there were cast and composite rotors. one is taller, measure yours.

 

Around the end of the 99 run they started to use a different rotor and hub bearing. The HAT part of the rotor is apparently taller. I believe the caliper was the same though. At least it looks the same. I have a 98 99 and 2000 D30 kicking around right now and have noticed the rotor sits a lot closer to the tie rod arm if you put it on the wrong hub bearing.

 

Calipers are the same just different materials. So far all XJ's I have owned from 97-2001 have had rthe same Bendex callipers

 

I am located in South Florida.

Thanks for the advice guys. I am going to measure the rotor today.
When I asked the parts store about the caliper, they asked me if the pistons were phenolic or steel. ????
