I recently replaced my front pads and rotors, I ran into a problem when purchasing the rotors that, from the sounds of it, is a common problem with XJ's. So I thought I would post up a little tip to avoid the problem, some of you may have heard of this problem, others haven't.

you may be sold a rotor that is to big, it says it is the rotor for your Jeep, and really, it is. but the quality is shotty and they range in diameter. so you will need to measure your rotors when you purchase them. this is the face you need to measure.
this is my old rotor, which I will eventually have turned/machined again. you will need to use a caliper to measure it, not the brake caliper, a digital measuring tool, I asked the kid at autozone to borrow a caliper to measure the rotor and he comes out with a brake caliper and says "idk how why you need this to measure it..." lol. the part you need to measure came out to be 50mm on my original rotors, I measured it in millimeters because I couldn't figure out how to change the calipers over to inches, it isn't exactly 50mm, there were a few tenths of a mm but I dont remember the exact measurement.
they gave me this valucraft rotors, one fit on the drivers side, the passenger side got hung up on the tie rod when the tire was bolted down, it happens when they are too big, it was 52mm wide

this rotor was 49mm so 1mm under the original size. worked perfect. so, when looking for rotors, I would say grab ones that are 50mm and below.

this is of course on a stock application and I don't know if it applies to lifted jeeps
