zagscrawler Posted May 22, 2011 Share Posted May 22, 2011 Does anyone know if i can put my d35 backing plates onto my new (to me) 8.25. My truck in an 88 and the 8.25 came out of a 98 cherokee. Thanks Zag Link to comment Share on other sites More sharing options...
mvusse Posted May 22, 2011 Share Posted May 22, 2011 I have ZJ D35 disk brakes on my 8.25", and the bolt holes lined up. I imagine the bolt holes on an MJ D35 would also match an XJ 8.25". You will have to drill/grind/cut the center hole out to fit over the larger axle tube. Link to comment Share on other sites More sharing options...
zagscrawler Posted May 22, 2011 Author Share Posted May 22, 2011 Sweet man thanks. i can handle a die grinder like the best of them. oh and also do you think i can use a stock xj spring plate or do you think i can get away with spreading the holes in my mj plates?

Geonovast Posted May 22, 2011 Share Posted May 22, 2011 I'm pretty sure the pre 90 D35 (non-C clip/10inch) backing plates will not fit on an 8.25. The 90+ D35 (C clip/9inch) backing plates are identical to the 8.25 backing plates, except the center hole on the D35 ones are a bit smaller, so would need to be reamed out.

zagscrawler Posted May 22, 2011 Author Share Posted May 22, 2011 well darn..... :idea: wait this just means i need to find some rear disc mods lol. So on that note, anyone know of a direct bolt on set of disc brakes that will fit a 98 8.25. If i have to use zj rears and cut the center i will but looking for a bolt on. I just put on a new master cyl. but if i have to replumb and replace its cool. long as i get disc in the rear. Also the front brakes on my beast are in need of some reworking. If there are a better (larger) set that will bolt to a d30 from a later model jeep i would love to know where to start looking. Thanks again, Zag Link to comment Share on other sites More sharing options...
Geonovast Posted May 22, 2011 Share Posted May 22, 2011 AFAIK, the only complete bolt on set of rear discs for an 8.25 is off of a Liberty 8.25, and I've not been able to verify that no modification is required. Link to comment Share on other sites More sharing options...
HOrnbrod Posted May 23, 2011 Share Posted May 23, 2011 I have ZJ D35 disk brakes on my 8.25", and the bolt holes lined up. I imagine the bolt holes on an MJ D35 would also match an XJ 8.25". You will have to drill/grind/cut the center hole out to fit over the larger axle tube. The axle flange bolt patterns are completely different between the c-clip D35's and the non-c-clip D35's. The non-c-clip D35 flange matches the D44 flange. So it matters which D35 axle you have. And mvusse, for my own personal knowledge, I didn't know the D35 holes matched the XJ 8.25. ASSuME you are referring to the non-c-clip D35? Link to comment Share on other sites More sharing options...
mvusse Posted May 23, 2011 Share Posted May 23, 2011 Off a ZJ, so C clip D35. As Geonovast already posted, the non C clip ones are different. Link to comment Share on other sites More sharing options...
