I performed a search on this and couldn't find a whole lot of info.
I currently have a D60 out of a J4000 Jeep truck and the stock brakes are shot. So I decided that it would be in my best interest to go ahead to switch to disks in the rear. Why spend money on the parts to get my drums working, when I want to convert to disks at some point anyway. So, I need to know what are some places that you can pick up caliper brackets for my application D60? The rear drums on this axle are fairly narrow when compared to others.
I understand that I will need 3/4 ton D44 rotors and matching calipers, but I am not sure on what caliper brackets to use. Any advice that you guys have would be great.

I know for sure that David @ www.metalfusionfab.com has a rear disk setup that will bolt on to Jeep J truck rear 60's - he used the rear 60 from my J20 truck as the template to set it up ;)

He also has a less expensive and more universal weld-on kit that might work on that axle as well.

www.speedwaymotors.com has them weld on style and also TSM, bolt on. Call Skip at TSM 303-688-6882 :D

Race shop caliper brackets scare me - they are awful thin for serious off road use and trying to stop big tires... I seem to recall more than a few have riped right off the tube.

I am not too fond of the race car caliper brackets either but, I think the installation is as much a factor in them "ripping" off as the materials of the bracket. I was just giving him some options. I personally run the TSM brackets. 3/8" thick, with 4, 1/2" grade eight bolts holding them to the flange. I think www.aa-mfg.com also has some brackets. :D

Edit: Speedway motors also offers flat plate type weld on brackets and not just the thin brackets.

Try Todd here: http://www.desertfab.com/disk_brake_kits.htm

this is much cheaper for what you get than the other places listed here.

Anybody else have some places that just sell the caliper brackets? Most of the places listed look like they don't carry something that will work to replace the skinny drums that I have. I want a bracket that I can bolt on. Maybe that will clarify a few things.

Did you call David @ MetalFusion? He just sells brackets, and if your J truck rear 60 is like mine - they WILL work.

not necessarily ... his axle is out of J4000 ... it could be a six lug semi-floater ...

He mentioned using 3/4 ton rotors and calipers - so I would assume since he plans to use 8 lug rotors he is already 8 lug.

you're probably right ... it's an 8 lug axle.

Isn't David's site www.metalfusionfab.com ?

Thanks for the help you guys. Yes my axle is an eight lug. The only reason that I was asking for more help is becuase I think that the J20 rear axle has a different drum setup than the J4000 that I have. If your J20 rear end has the drums that are similar to the ones used on Ford Dana 60's, then I think that caliper bracket will not work with my Dana 60. My drums are a lot skinnier than most Dana 60 drums. They almost look like 1/2 ton drums. If you want, I can take a pic of the one sthat I have and compare them to everyone elses. Thanks again for the help.

The size of the brakes, ie: drums, shoes, etc. shouldn't have anything to do with brackets for a disc setup. All you should need to know is the bolt pattern where the backing plate attaches to the axle flange if you are using bolt on brackets. You may end up putting the bracket either inboard of the flange or outboard depending on the relationship of the caliper to rotor.

TSM will sell just the brackets if you ask them. 303-688-6882 talk to Skip.

Sorry about that - edited the original to be correct now (duh!)

Yea...because after all, stopping a 44" tire at 0.8 mph has to take a LOT more braking force than braking a stock car in the corner?? Phuleeeeze!! Think about how silly that is!

Oh yea - AFCO and BRP sell brackets too

I dunno guys, a disc brake caliper plate is super easy to build, have you considered that option?

These are from Speedway motors. Bout $14ea.

Although SHAKERS 14bolt caliper brackets make these look elementary.

It might be easy to build if you had all the right tools at hand. I don't have easy access to a cutting torch or plasma cutter. So that takes away my ability to easily cut 3/8's plate.
I will call Dave and talk to him to see if his brackets will work. The fact that Speedway motors claiper brackets are so cheap looks nice, but I would like some brackets that are 3/8's or thcker. I would also like them to be bolt on.

Thanks again for your help guys.

Buy 2 brackets, stackem & weldem together at the edges, cut off whatever isnt necessary. I might later on, I had to have a spacer anyway.
:beer:

I had thought about that REDDMANIAC, but they are still weld on brackets. I would like to stick with bolt on brackets if possible. Thanks though for the suggestion.

You think about it.


Or, how about I spin a go cart tire and you put your hand on the tread to try to stop it, or I spin a 44" bogger and you put your hand on it and try to stop it.

I guess rotational mass, and the larger diameter are irrelevant, right? :rolleyes:

But I guess the post just a few months back hereon PBB showing exactly that - cheap rear brackets ripping off the housing is irrelevant :p

Way to change the argument to try and support your point!! But I'll bite. I NEVER said weight and diameter were irrelevant.....however, it appears you don't understand what brakes really are, or how they work. The are NOT "wheel rotation stoppers". They are energy conversion devices. We know energy can not be created or destroyed, just changed from one form to another, right? Well, brakes stop a car (or a single spinning wheel) by converting the kinetic energy of that car or wheel to heat energy through friction. Sure, a spinning 44" bogger has a lot of kinetic energy - but if you are claiming it has more kinetic energy than a ?? thousand pound racecat doing 150 mph, I think you are mistaken.

But I guess the post just a few months back hereon PBB showing exactly that - cheap rear brackets ripping off the housing is irrelevant

It is indeed completely irrelevant unless I know who and exactly how it was welded. Just because something breaks, doesn't mean the whole idea is bad....execution counts for a lot.

I mean, I could take a big 1/2" bracket of 4130, do a piss poor welding job, not properly heat treat and stree reliev after welding, rip it off, post a pic, and eveyone would be quoting the gospel of how weak 1/2" 4130 brackets are. :rolleyes:

I'm not fond of the way-too-common occurance of people taking a single or few second-hand occurances and starting urban legends about stuff in this sport without really understanding the facts!

NOT that I'm accusing YOU of that, David ;)
