350MJ Posted June 6, 2014 Share Posted June 6, 2014 I have a dana 35 rear end right now and i am currently redoing all my brake lines after this past winter the negative 30 days were cold enough to burst my brake line. i figure since I'm going through all this work i might aswell convert my rear brake drums to disk brakes. I know some of the grand cherokees later came with rear disk brakes i just want to know what all do i need to grab from the grand cherokee at a junk yard to convert them I'll end up buying brand new calipers and rotors and pads from the store but i still need all the mounting hardware. any suggestions or advice from anyone who has done this?

Timeless Posted June 6, 2014 Share Posted June 6, 2014 Grab parts from a ZJ with a dana 35 if you're set on doing the conversion. DIY: http://www.links4jeeps.com/writeups/d35discconversion/ Link to comment Share on other sites More sharing options...
cruiser54 Posted June 6, 2014 Share Posted June 6, 2014 94 to 98 ZJ. Be sure to get the studs that hole the caliper bracket to the housing. They're longer. And also be aware that you need longer rear axle wheel studs. Another thin is to use a 3/4 " wrench/socket and grab the "guts" out of the donor vehicle's proportioning valve to transplant into yours.

Incommando Posted June 8, 2014 Share Posted June 8, 2014 The best thing that you can do is a dual-diaphragm booster upgrade. Link to comment Share on other sites More sharing options...

Not sure about '08-up KJ. Starting in '03 rear discs were standard. Link to comment Share on other sites More sharing options...
