you did an AWESOME job on the video, but one thing im going to add for anyone watching this is that if you have the 8.25 rear axle, you can use the back plate from a KJ jeep liberty and you dont have to dremel it out
So what you're saying is this process is even easier on a KJ? Mine had an oopsie and needs a new axle, figured I'd put discs on it to save some headaches in the future since the shoes are 75% gone anyway.
@@steveyoung6268 2002-2007 should work, I know a 2005 works perfect. Grab both side Ebrake cables up to where they connect from double to the single bracket. Grab the entire rearend of you can, basically everything can be transferred over. I think you do need to get longer bolts to hold on KJ backing plate.
@@msack6904 ......great to know as I have a liberty that got t-boned. It has a new motor and trans in it so I bought another liberty 4x4 with a blown motor....once done I will have spare parts and won't have to crawl around in a wrecking yard.
I watched this just for the fun of it. You did a fine job explaining the whole procedure. Great what you are gonna need also. Just plain excellent and video. Anyone wanting to do this would accomplish the task easily. You did good !
I'm glad you mentioned the importance of the proportioning valve. I've seen plenty of rear disc brake swaps over the years. I'd say,probably half the time that never gets changed.
Seems like you really know what you're doing. Clear, precise, and altogether a great tutorial! Wish I could rent you for the day to help do my brakes! :D
I just did this mod over the weekend and your video helped immensely. I watched it a few times before starting the project and breezed right through it. Thank you for posting!
The reason your brakes were "malfunctioning" is because the spring on the gold "pin" in the rear shoe was not mounted properly to the adjuster. It should have been wrapped over the adjuster instead of hanging down. It pulls the adjuster up to the spreader and allows you to adjust the spreader by turning it and that spreads it apart. To close it, you actually apply pressure to the adjuster downward and then you can screw it together further and that closes the gap at the bottom between the two shoes. I learned this as I just did my rear brakes today. I may look at doing this in the future. Great video!
+sizzlinbacon21able It's actually all the way it's supposed to be (I did extensive research on this.) What was wrong is there was too much slack on the auto-adjust cable, which I suspect was either defective or just the wrong part. Regardless the discs have been totally maintenance-free since I put them in.
This is something I will be doing in the future for sure; looks like a good conversion, and lets be honest. The xJ's breaks were never the best in the mountains.
Awesome vid, followed this as a base for my swap that I'm doing this weekend! However I'm not crazy about the how you routed the brake lines - I'm going to avoid going over the leaf springs like you did. Anyway, thanks again for making this video !
Nice clear sharp video! I need to do this to mine. Maybe your next video could be a 4-wheel drum setup. LOL...But seriously, thanks for sharing this info!
Casually drives past a 3/4 ton moose and doesn't mention it. Great tutorial, I'll be converting to discs asap, just bought a 3 inch lifted XJ on 33s and the braking is almost worse than my 5 ton E350 shuttle bus I live in.
Great video. Thanks for all the info! Also, if you like to use nitrile gloves while you work, then you might want to check out "Venoms" from Lowes. They are black nitrile gloves, much thicker and far more durable than the regular, examination style gloves that you seem to be wearing. EDIT: Nevermind! I see that you started using them later in the video. Ha!
Mate just watched you conversion, only thing I would add is to burr over the Ubolts so they don't vibrate off. Oh by the way great informative video. I was considering doing to my xj. Thanks
Excellent video !!! Just one complaint, i had to call my brother and have him explain to me how this would get rid of my problem replacing my front brakes every nine months yeah I know I’m not so bright but I figure if I suffer a little humiliation maybe you next time save somebody a little humiliation!!!! Thanks 🙏
I owned, a 2001 XJ, ( still miss it ), I used a rear 2005 Jeep Liberty KJ rear axle to use the disk brake parts, and is a throw, everything fits, the only thing is that you have to adapt the hand brake cables that goes from the wheels to the attach point under the drivers seat, no valve switch, and it improved braking lot, I also started to abuse in the downhills that I was scared to drive when being a drum braker...
From the 2005 Liberty used the brake components, bolted to the original XJ rear axle, no adaptations, you have to remove the shafts on both axles to be able to remove the hand brake plates, put back the shafts ( replace seals ), a the rest is just put everything together, remember that the only thing that you need to adapt, are the hand brake cables, from the wheels to the base that is below the drivers seat, underneath the Cherokee. Good Luck
wow thank god for this video I'm going an 8.8 swap with disc brakes in my xj and I wasn't sure exactly how to do the proportioning valve. So all you did was unscrew tha cap and plunger thing and screw in the new one from the zj? thanks
There is more peddle travel due to the master cylinder not being for 4 wheel disc so the rear is set up for low pressure/hi volume for drum rear breaks, when it should be fore hi pressure/low volume.
i have an extra jeep that i use for parts, could i turn the rear end drum breaks to disc breaks from the front end? then add it to the jeep I'm working on
Ok appreciate it, i bought 98 and it appears previous owner did the mod you did but hand brake doesn't engage. (Mine is 5spd).. I tried tightening from underneath but obviously that's not going to to it. So I'll have to look at your vid once more to see what you did. Don't know if i want to weld. But if i did, would i cut off same amount ?
I’m slightly confused on the emergency lines. I have the same set up as you. Two lines come from in the Jeep straight out. Do you cross them over and use the drivers side line on the passenger side caliper? Did you loop lines anywhere or just over the axle?
Hi, great work you have did here and i want to do a conversion on my '01 XJ. Thing is that i have ABS. Where should i fit the ABS sensor from my XJ to this new plate? With respect
I can tell in the video the guide plate for the brake ebrake cable is not set in the hole that the spring goes to. You need to press in on the spring and the plate with your left hand while forcing the spring on with a flathead. You will know if you did it right because that plate will not move at all and will barely turn if you pry on it. The gap is actually about the same size as the cable and I had to shove the cable through with a flathead.
Great video! I did the conversion this weekend using this video. Did you happen to have the brake warning light come on after the swap? Mine is on and can't figure out why.
on the 1998 grand cherokee you harvested the parts from, what type of engine you had to use for the new calipers? there are 3 types for the 1998, the V6, V8 5.2 and V8 5.9 which matters on the caliper because it is made differently.
Dan H here is a PDF in the following link that might come in handy. Haven't read it all. www.jeepforum.com/forum/#/topics/1277932 I might be doing this mod around mid 2021 with my work schedule 😂
what size wheel studs should i be looking for ? and did you replace the whole proportioning valve (the aluminium block that the brake lines attach to) or just the 3 parts shown at 0:55 ?
Skyler Tremethick sorry, but no.. i am not sure what wheel studs are needed and in this video it appears that he did not replace the whole valve assembly, just the internal valve, spring, and cap. I ended up swapping in a Ford 8.8 with disk brakes, deleted the abs system entirely and had to swap the entire proportioning valve out for one from a Cherokee with OUT abs. I Had to swap out my proportioning valve for the non-abs version because the abs version has 4 lines out to go to abs pump and my new valve only had 3 (2front 1 rear) I ended up going to ford 8.8, 4.88 gears, lockers front and rear, 5.5 lift, frame stiffeners, homemade bumpers, sliders, and more. I just could not put that much work into a Dana35. But probably worth the effort if u have the Chrysler 8.25 or Dana44
pankas pankusa did you use the zj sensors that are fitted for the zj disc backing plates? What did you do about the tone ring? Keep the xj tone ring? Or got new zj tone rings??
I have a real ?for ya... I have two 99 jeep Cherokee sports 1 automatic green w/ an 8.5 axle n a 99 manual w/ a Dana 3.5 axle will this work on both my vehicle???
I have the same exact issue with the auto adjusters on mine. The rear brakes back off after a few miles. The issue is - you do not have the correct spring for the plate; the spring is supposed to hold the plate in the correct spot, which will keep tension on the auto adjuster cable. It's not something YOU did wrong. I have gone through 4 or 5 sets of hardware in the last few years, rebuilt the stupid things numerous times. NOT A SINGLE SET of springs has the right spring.
I did my rear drums on my 89 xj and they fell apart on me twice while driving within like 2 weeks. my buddy whose a mechanic rebuilt them the same way I did and they haven't fallen apart or anything. it's bull
tnoutside yea I was out there with a pair of pliers and a screw driver lol.. and yea the dork at the parts store gave me the set with the hold downs too long. that's why the fell apart the first time. the second time I have no idea. it just said fuck you I quit. at the SAME intersection. I think the E brake cable runner thing jumped it's spot
Could you put up the new bolt sizes and nut size for the backing plate to the axle, as well as the new stud sizes for the ZJ? If you could also put up where you got that U style bolt to hold the e-brake line, that would be awesome! Thanks!
