I’m rebuilding an 87 Cherokee. Rebuilding the Dana 30. Goin 1 piece shaft. Rotors hub pads and calipers are shot. Want to replace with new but only finding calipers for 90 and up. Can I use 90+ parts or do I have to change my knuckles? Staying with 15” wheels. I tried to pull up stuff on here but find everything but what I need to know. Also the internet is full of bla bla bla but no info on what I need to know. Will post 90 mount and work on pre 90? Wouldn’t mind upgrading but I’m not gonna spend gobs nor am I goin to a wrecking yard for wj or whatever. I just wanna know if these years will interchange. Thank you guys for your wisdom in advance. New to the jeep world and have figured out and learned a lot but some things elude me.

 

The calipers do not interchange. The early model, two-piece knuckles are nice because you can fit larger rotors by using a custom caliper mounting bracket. Brembo even makes kits. Rockauto.com carries multiple brands that will fit your '87.

 

so to use later ones that d need to swap out knuckles to. Kk thank you so very much! Not sure if I’m replying correctly or not. Not very technical at all. But thank you again!

 

Yesh those early knucks make it badass you can run all kinds of stuff. Worth it over stock brakes, i dunno know.
