Who's using them?
What did you spend?
Any surprises?

Looks like B.C. Broncos has the best prices for conversions

Appreciate your input,

Scott

If you don't mind a little fab work and hunting down the parts, you can do as I'm doing now. I bought the calipers, with brackets, lines, rotors, and parking brake cables at the pull it yourself for $35. They are off of a '92 Grand Marqui and are simmilar to the Explorer set up. The have a caliper for the service brake and a small drum and shoes for the parking brake. They bolted to my housing after trimming a bit off the bottom of the flange on the housing. The rotors had to be redrilled to 5x5.5 pattern and the center of the rotors had to be opened to fit the pilot on my axle.

I have the drivers side together and plan on finishing up the pass side tomorrow. All my pieces were in great shape so all I had to buy extra was a new set of pads for $20. There is also a piece I need from Lokar that will adapt the e-brake cables.

I have BCB caddy rear disks with the e-brake. Love em except for the e-brake. the disk e-brake is a real pain to set up at first and it is not famous holding power either. but once setup properly the e-brake holds good (not great like self accuating drum brakes do). still was a good upgrade. i have power front and rear disks and the stopping power over drums is well worth time and $.

There are a number of us running disk brakes on the rear. In my opinion though I would not go out of my way to add them because they are not going to add a lot to the braking power. On mine it was only a couple hundred dollars more to add them since I had to get a complete rear brake setup anyway. On mine I run the Explorer SVO kit from Ford Motorsports which is a direct bolt on for Big Bearing axles. They do however require a specific offset on the axles. For someone that is also getting new axles or that has the medium duty housing it is the cheapest kit that uses all new pieces. (About $425 for the kit) It also has one of the best E-Brake setups of any of the disk brake kits. If your looking to add more braking power then I would do front disk brakes and hydroboost first if you haven't already done so since they will both provide a much bigger difference in braking power.

Post some pics when you get all those pieces put together. I've seen those setups at the yards and was wondering how they would fit the 9".

Personally, I use the one off a 78 Lincoln. Complete and the Ebrakes work.
Todd and I love discussing this one but its the one I use.
Last setup complete set me back 75 bucks.

I agree that rear disc is way overrated, and unless you use the exploder kit, you'll likely end up disappointed with the parking brake. However, I generally will convert my axles to disc just for ease of maintenance and inspection, but I'll wait until the drum stuff is worn out.

I run rear disc with caddy calipers. They lock 36's no sweat, but the parking brake is useless. Then again, I will never trust any parking brake. You should always try to park in a way that your vehicle can't run away.

I put the exploder kit on mine. The parking brake looks like a pretty slick setup - very easy bolt on when I got my new axles (had them made by Currie). I haven't "run" them - and won't for quite some time. Still building....

Here are the pics of my parts. They look very similar to the exploder parts. I just went through the yard with my tape measure and found an axle that had the same 3.25"x2" bolt pattern as my axle. My EB axle also had the 2" wide drums which gave the axles the 1.5" backspacing needed.

Also note that I don't believe this set up will work with the stock shock mounts. Mine are inboard mounted.

The explorer discs won't work with the stock shock mounts, either (unless you mounted the brakes backwards - but then the parking brake cable wouldn't work out very well).

If the calipers are mounted correctly then the stock shock mounts will not work with any of them that I know of.

Bucketobolts,

You have the small bearing rearend, right? That is what I will need. This looks like it might be an economical way to do rear disks. I'm going to check the wrecking yards tomorrow for pricing.

Thanks,
Renard

Boy, are you right!! Guess who forgot this little "detail" when he was doing his Lincoln discs on a small bolt/small bearing rear end. Yes, I got the discs to fit great but the shocks did not work. I got PO about this and designed a dual shock setup for mine. The material to make the dual setup cost me 15 bucks but it takes time to make it all.

I also didn't think about this detail and came up with a design to allow dual shocks and the disc brakes....the design is still on paper, though. Like I said before....still building.

Yes, I still run the original '72 small bearing diff housing. Since I've already mounted my inboard shocks and traction bar, I've been alittle more hessitant about swapping out to a BB housing. Measure your flange bolts. They should be 3.25"x2". Then make sure the vehicle you pull the parts from has the same diminsions. BTW these did come from an 8.8 diff housing.

Thanks. I may have issues with this after all. I just mounted the dual Duff shock system in the back and the backside shock may hit. Thoughts?

I wonder if those Duff stage II hoops can be mounted on the inside frame rail instead of outside? move aside the wiring and gas lines. Then cut off the lower mount on the axle and move it inwards?

I think that is a no go since it would require the floor board inside between the wheel well humps to be modified even with a 2" body lift.

I'm with Saddleup on this one, except that I did the hyrdroboost/front disk part first and was planning to finish up with the rear disks..until I found out how well the hydroboost worked. My word!..I can't use all the brakes I have now..I sure don't need more.
