rear disk brakes
After l looked at the condition of my rear brakes I decided today to put disk brakes on my Mare. I used this 2870 company when I did rear disk brakes on my Mule and thought about using them again. But, its been 5-6 years ago and since then I've read of others using different companies. I want a kit so I'm open to all suggestions. I'm not saying that TSM is a bad company, I had good luck on the Mule. When you pull the weight I do, every little bit helps!

Bronco graveyard sells a kit. But im not sure what the name brand is. I will have to post it up when im not on my phone. It uses a 78 catialac (sp) elderodo caliper i belive. Edit: look in the tec mod stickie. There is a couple other options. Black bird customs was one of them.

IIRC a lot of the bolt on disc conversions use the single piston calipers which arent exactly made for heavy duty applications.
I think in another thread or discussion regarding rear discs people thought the best way was to get an F Super Duty axle which came factory with disc brakes that had dual piston calipers.
At the same time you can rob it of its hydroboost...
Thats just me going off of memory... Also somewhere over on powerstrokenation there was a guy who did a bunch of hub work to convert to disc brakes.

Thanks Alex, I don't want to get to involved with this. I did notice on TMS site something about dual calipers for an extra $$$, LOL. Being a dually I don't know how that would play into upgrading axles. I'm going to spend time sound proofing and fixing my up pipes and also fixing a manifold leak so I don't want to get to involved.

The only one I have any experience with is TSM. The kit that I got is on my F150 though and it doesn't pull anything. Lol. That truck does stop amazing though. I think I would try out the dual caliper kit, one with parking brakes. You may need to get a proportioning valve though because you will be increasing the braking power on the back quite a bit with an extra 2 pads and a caliper.

I have always questioned using car calipers on a heavy duty truck. Plus I have laways heard the parking brake on those things are a pain over time.
I would go SD rear axle swap... should bolt right in and you may be able to sell your axle and make up the difference.

EDT: what size rims do you have? are you running 16's or 17's?
EDT2: you could even go 3.73 and get better gas mileage or up to 4.30 to empty your tank quicker.

That would be a grand idea if he wanted to figure out a way to mount up SD front brakes, use the SD lug pattern, and swap wheels... I don't think it's worth the effort in this scenario. I guess he could re-drill the calipers for the OBS lug pattern, but this would need to be done again every time you have to change the rotors from now on...
No need to change the front. I have been researching this for a little bit now.
It seem that the vans maintained the 8x6.5 all the way to 2011/2012. and they were available in a DRW rear axle (dana 80).
now, the 05+ went to the bigger rear brakes and a 8x200mm (DRW only).
I just don't know if all D80 disc brake hubs interchange or why they went to the 8x200. if they made the hub bigger because they made the bearings bigger then I do not think you can convert the 05+ to 8x6.5.
it all depends on the diameter of the center of the hub.
However, a 1999-2004.5 SD rear with either re-drilled or van hubs will work just fine (according to my research).
Richard
EDT: he will also need 17" wheels if he goes with the 05+ (hence the whee size question).
EDT2: I just confirmed that E350 DRW hubs were the same from 1999+ (via car-part.com).
EDT3: so the last question (relating to the 05+ axle) is if the rotor has the same bolt pattern from 1999-2012 on the F series trucks. if so, using the van hubs should work even on the 05+ axles.

Agreed. If you want disc brakes, the easiest way to go about it with out having custom hard to replace parts would be to put in a 99-04 SD rear axle, Econoline rotors and have the hub redrilled for the OBS pattern

I just noticed I said re-drill calipers in a post above. I must be tired. lol
Going to the SD axle seems like too much hassle to me and possibly even too expensive... Keep the stupid drums..... lol

The van 70 hub will fit on a Sterling 10.25?

Glenn,
You might hate drum brakes, but if you tow heavy think long and hard about changing first.
IMO there's a reason why the big rigs still use drums.
And I have yet to read ANYWHERE about someone being happy with a disk conversion when towing. I've wanted to do this 'upgrade' myself on my '96, but the only real upgrades I've read that are worth doing are:
1) Convert to Hydro-boost.
And/or
2) Swap to a SD axle.
I've read post after post how disappointed guys are with working a truck hard with the conversion kits with eldo or GMC calipers.
There are a couple posts about just converting to Hydro-boost and drums and the truck will darn near put you through the windshield when towing.
IMO you have to have Hydro-boost with a SD rear axle (or disks I guess) anyway, so why not start there, and if you still are not happy THEN look into rear disks.
