Decided I'd gather the parts needed to do rear disc brakes... I picked up an XJ D44 and I'm in the process of regearing (4.11 yukon) and adding a locker (spartan).

I went to the junkyard and pulled the backing plates, calipers and rotors off a 97.

Once I got home, I decided to test fit. The backing plate mounting holes (not the center hole) do not match the holes on the flange (on my axle).

I've been using this page as a guide and after reading it a few times I dont see anything where he mentions having to drill new holes or enlarge the existing holes...

Lastly, should I go back and the booster/master/prop. valve from the 97 GC and use in my Cherokee or will a 96+ (dual diaphram) work just as well?

Anyhelp is appreciated.

 

id do the booster upgrade first you will be so amazed at the difference in stopping power you will forget about the disc jobhttp://www.jpmagazine.com/techarticl...des/index.html

 

Found my answer...

Since I already have everything, I'm still going to do the rear disc. Not a fan of Drums.


thanks anyway.

 

ONly the crown vic brakes are a somewhat a direct swap. I did this swap a few yrs ago. You will need TJ RUBicon retainer plates. YOU will also have to have them redrilled, or you wil have to make a 3/16ths spacer ring and use your stock retainers.


When I did my swap.. Alloy Usa was selling the D44 alloy kits with dual bolt pattern and all hardware for 300 shipped, and that is what I did. By the time you buy all the stuff so you can put the right ends on the axles you are over 200.. so it only made sense to drop a lil more.

 

I found all that information in the link I posted.

This however doesnt make sense to me. Are you saying I have to buy new axle shafts or what?

 

NO.. by the time you buy all the new parts so you can install them on a d44.. it is only a lil more money to have new moly shafts.

 

sound like alot of work to get disc brake post how it ends up .......

 

BECAUSE you have to install a new axle reatainer which means removing the bearing retainer, bearing, and oil seal to install a new retainer plate. THATS WHAT IT HAS TO DO WITH IT.

 

Has alot to do with it. Guess he has money to burn by doing it twice. Pingpongs right, if your already replaces these parts upgrade to molt shafts. Oh wait I shouldn't comment on this cause its not about the brakes.

 

i'm thinking about a disc brake conversion kit, are they worth the money?

 

i've had nothing but trouble with the drum brakes. they lock up and don't stay adjusted. do you know of any brand that's a good deal?

 

Do you still have a stock dana 35? If so, just get a ford 8.8 from a 96-01 ford explorer. With alittle modification you can get a much better rear axle and disk brakes!


Rocko, Ployboy, Pingpong, can we simmer down a bit?

 

"a little modification" that requires cutting off leaf pads and welding new ones doesnt it? That doesnt seem little to me, especially if someone can't weld.

Also, aren't most 8.8's geared 4.10? Where as the 30 is most commonly 3.55? So that requires re-gearing, right?

As far as simmering down, if people would stay on topic, threads wouldn't get derailed... thus tempers won't flair.

Thanks for yet another reply that doesn't contribute to doing a disc brake conversion on an XJ DANA 44...

 

nominated....
