OK so I just bought a 93 Xj lifted with a RE 5.5" on 33's and needless to say the brakes suck. I started by inspecting pads and shoes and they all look fine. Secondly I bleed the brakes (kinda spongy) felt better for a few minuets then noticed a leak between the master cylinder and booster. I went to Autozone today and bought a new master cylinder and booster for a newer Xj but my question is should I exchange them for a Grand Cherokee master and booster? Thanks for the help in advanced everyone I'm looking forward to learning and milling around on this forum.

 

Should get a wj mc and bb then put disks in the rear

 

x2 on the rear disks you can pick up most the parts from a d35 zj and use the zj porportioning valve

 

I plan on doing rear disc in the future but for now I'm focusing on the master and booster.

 

Go to the u pull it junkyard by JC Tune Airport and get the parts there. Shouldn't be much at all and you can grab the disc conversion stuff as well. I'm planning a trip there soon as I live about 10 minutes away in Bellevue.

 

WJ BB/MC combo. made a big difference on my 93, but you'll want rear discs bc the master might make the pedal stiff with stock 9" drums.

 

93xjli a adjustable proportioning valve could help that problem i bet.

 

Later down the road you may want to think about the WJ knuckle swap. You get better brakes and better steering.

 

No, the WJ master is a bit large for the stock XJ brakes. Prop valve has nothing to do with it.

 

I was told a Dodge 2500 van MC would lock the wheels with 39 in. tires.

Do a search for the exact van year.

 

So, I have had an 89 XJ since 91 and the brakes have always been poor. So I am seeing talk about converting to discs.
What year, what model would I get them off of? What other parts would I need to complete the deal?
Is there a link to a "how to". I can't find one? Lots of rigs in junk yards around here. Need full name descriptions, don't understand all the short hand. Thanks.

I found the links I needed. Good info, thanks.
