Scottanchee Posted September 28, 2009 Share Posted September 28, 2009 I am going to be putting a 8.8 in my 88 MJ . I know I have to swap in a prop valve for a rear disc brake setup , but what about the master and boster ? I can get one from a 95 ZJ , Should I swap it in ?

MiNi Beast Posted September 28, 2009 Share Posted September 28, 2009 I didn't touch anything on my brakes when did mine, did just fine. Only thing to mess with was the level load valve thing, I just bypassed mine though. Link to comment Share on other sites More sharing options...
FireFighter32 Posted September 28, 2009 Share Posted September 28, 2009 I am interested in doing this swap in the near future also. Any details would be much appreciated. Link to comment Share on other sites More sharing options...
dakineJ Posted September 28, 2009 Share Posted September 28, 2009 Did you guy's use 95' Explorer axles? What kind of prices are peaple finding 8.8's for? Interested in more info on this swap as well. Link to comment Share on other sites More sharing options...
Pete M Posted September 28, 2009 Share Posted September 28, 2009 95-01 are the ones with disks. Older models are also acceptable, but will have drums. I've purchased them for as little as $75 at the pull-a-part, but 200-300 is an ok price if it's in good shape and has the brakes still on it (core charge for the calipers is ungodly high) Link to comment Share on other sites More sharing options...

Like Pete said, $75 at pull a parts. I picked one up a few weeks ago for $143 with rotors, calipers, etc. Just the bare axle without the brakes was $75.

Pete M Posted September 28, 2009 Share Posted September 28, 2009 also, don't get a 3.73 ratio unless you can find a front to match (or can pay for a regear). 3.73s were a fairly rare ratio in XJ/MJ Dana 30s. They are common in low pinion 30s though (ZJ/TJ), so if you're going to be at stock to 3" of lift, that would work. Link to comment Share on other sites More sharing options...
TrailReadyMJ Posted October 5, 2009 Share Posted October 5, 2009 I too didn't do anything special with the brakes when I did my swap. I just "permanently" adjusted the load sensor to make it think there was more weight back there, thus giving some extra pressure for the discs. Worked just fine, and stops much better than it did with the worn out drums! Link to comment Share on other sites More sharing options...

I wasn't hauling wood either. :thumbsup: Link to comment Share on other sites More sharing options...

Every PU I ever had will generally lock rear tires first anyhow. CW Link to comment Share on other sites More sharing options...
