I guess first thing to try is a rotor from auto zone for a 2000 Cherokee see if that helps at all with the calipers

The other idea I have is shimming the caliper bracket out with a couple of washers is this advisable? This should in theory give me another 1/2-“1/4” of pad seating area right?

Be better to just use the proper parts.

I agree I will try the rotors and post back

So rotors did nothing for fitment I am thinking the pads maybe are too thick. I know The answer it’s not possible for that but I think this is the case. The old pad which has roughly 1/4” of material fits great obviously. Not sure what to do here. Are there different pad thickness I could look at that will fit on the Jeep?

i am also hoping the master cylinder will get my pedal back and at least I can maybe use the pads I have now.

Does anyone know if the caliper brackets are different on different year cherokees?

They had 2 different unit bearings with 2 different rotors. Also, I don't know what all years they did it for, or if it was even done on the 4wd ones, but my Comanche is an 87 and has a spindle and the rotor is part of the hub. From what I know from personal experience there are 3 different rotor types, 3 different hub/unit bearing types, and at least 2 different caliper types.

OK it's got an 8.8 with discs on the rear

When you start to get into this mix-master stuff unless you actually did the conversion you just have to start swapping pats til you get lucky. Are you sure it still has the original XJ calipers upfront?

i agree with you on that. Once I do the rears it will be another story but the front were shot to hell. I think I have narrowed it down to have 1999.5 and newer hubs because of the 3/4” lip. But upon more reading it seems like some bearing companies interchanged the two. The biggest difference is in the overall height of the bearing which effect rotors placement in the caliper. So f-ing a man whyyyyyy must this be so stupid. I’m not changing out the hubs I mean I guess I could but why. Anyway it seemed like caliper and caliper brackets were the same for all years just hubs were different.

I am bringing in to auto zone the old rotors the new stoptech ones I am trying to put on and then also the 2000 Cherokee rotors I just bought to check them all out height wise etc. I will get to the bottom of the different year rotors tomorrow and report back.

Is there anyone who has a picture or can snap a picture similar to what I took for comparison sake?

specifically how your calipers and pads are setup

So I replaced master cylinder and I have a pedal again.

I am going to re bleed again however.

Also going change tcase fluid fluid and output shaft seal. I’m losing fluid there. I still have a vibration that gets better when accelerating which leads me to think I need to adjust my pinion angle more. I am going to get an angle finder and figure out the angles.

Hello so I got some progress made on the driveline angles. I found my pinion is actually -2* from measuring from under the pinion on the flat surface of the 8.8

the transfer case is right 0*

i have a double cardan drive shaft but think I can get away with maybe a single and not have to tilt the rear as much.

From the measurements I need 2* shims to be at equal angles. This should solve any of the vibes I am getting right?

they are happening when the driveline becomes unloaded. I’m set acceleration it is vibration free. My idea was to tilt up 2* and set the track bar there so it doesn’t move on acceleration or deceleration.

If if I run the double cardan which is what I would like to do I think I may need to rotate more than the 2 degrees so they essentially make a straight line

Yes, if you have double cardan, just make it a straight shot on the pinion
