Rear disc brakes

When you get done swaping spring purches and posibly gears you still have an unreliable D35 axle. 95+ Explorer 8.8 is a much better swap and not too expensive. Take a look at this post from our club:

I was looking at the total amount of money that the person in that website put into installing the rear discs and I have a couple coments regarding his application and yours.
He instadded on a TJ with a D44 and you probably have a D35, and his total cost was ~$500 fust for rear breaks.
As Ritt Mentioned about, your best solution would be to probably source a used 8.8 out of a 95-99 explorer and use that rear end, can be built for less than $500 and not only will you get rear discs, but if you prep the axle properly, you will also get a rear end with 31 spline axles that is stronger than a D44

www.car-part.com is a good search tool for an 8.8 across the US and locally. I've seen 'em with 4.10 and LS for as low as $300.
I have a 95 YJ with a built up dana 44 in the rear. I have the standard drum brakes and am looking to go to discs but the ebrake cable seems to be a problem. I haven't found a conversion kit for a 44 in a YJ that includes the cables. I wonder if the TJ kit will work?? Any thoughts out there.
hoesntly, been 7 years since I posted in here, since then, I have found the easiest way to install discs on a drum axle is to fab up the parts from scratch. I usually start with a 1984 Cadillac Eldorado rear caliper, I would source a rubi rear rotor, then I make a simple flat bracket to hold the caliper and weld it on. you will have to change your rear e-brake cables to the cadillac ones, but I've done it a couple times on tj axles, not super hard, just takes some fab skill

The E Brake Assembly off a 98 grand Cherokee will fit your YJ clip and mate up for the rear e brakes. I stole the whole Assembly off an 98 grand with Dana 44 (alum) with disc brakes, the only things I had to buy were the new retainer plates and longer studs for the axles since the disc rotors are thicker than the drums.
You will have to cut the hard lines to fit then re-flare them. Not a problem just take your time here. The last thing you will need is a manual proportioning valve, to set the bias for the rear discs.

Thanks, the pictures are great and will help. The guys up in Casmere, Wash. that built the 44 for me actually found a outfit that makes the cables up for my YJ and now the kit is complete and in a week the project will begin. There is a lot of input as to whether I will need a new Proportioning valve and one off a 4 wheel disk TJ or Cherokee has been suggested. I guess I will know when I get it together. Thanks again.

Gary, the proportioning valve is the sticky thing, you can mod in Grand Cherokee's or even a Cherokee but they are made for a heavier vehicle, it still applies too much braking to front discs. Then the newer TJ's, just before the LJ's(2003-2006) came out have a ABS pump add on problems that require allot of change over to add wheel speed sensors.
There are two fixes available, one of them is manual proportioning valve and the other is a complete aftermarket change over to hydro boost braking system. I can find the link on Stu's web site.
But the main reason we are trying this conversion is to have brakes that mimic the family car or some other vehicle we have or had drove with real brakes.
Even after the conversion to disc's your going to be disappointed, I was. You can spend money chasing the right proportioning valve (280$ so far) or just order a manual one from summit and get the rears to bark slightly at a full stomp. The braking power just isn't there (have read some where a 97 Dakota is like a .750 dia and will mate up to jeeps fire wall with a modified rod...). Now I have been saving to go to a full hydro-boost system, on all accounts I have read that it will give me the braking power I am looking for.
