just bought a 14 bolt for the ol' YJ. HUGE DRUMS! I want to convert to disc for weight saving and also to run smaller wheels(15" instead of like 16.5") who has done this or knows of a conversion and its price. also, is there a stock 14 bolt out there with discs(junkyard upgrade)?
also advise on a full floater kit if possible

Make them yourself, I used calipers off of a 96 chevy 3/4 ton 4x4. The rotors are off of a 3/4 ton Chevy 4x4 around 80 model with the Dana 44 and 8 lugs, you need to build a plate for the caliper out of 3/8" plate and this will bolt to the old drum brake backing plate bolts. The HUGE drums you mention need to have the studs knocked out of them and the hub will seperate from the Drum. And yes I have 15" wheels on mine..

Hope this Helps..

I am also doing this conversion soon. Here is the info I have found:
<A HREF="http://www.off-road.com/chevy/reviews/tsm/" TARGET=_blank> http://www.off-road.com/chevy/reviews/tsm/[/url] http://www.truckworld.com/How-To-Tech/ChevyDiskBrakes/Chevrolet-brakes.html http://coloradok5.com/forums/showflat.php?Cat=&Board=blazer4x 4&Number=212538&page=0&view=collapsed&sb=5&o=0&part= http://www.pirate4x4.com/cgi-bin/ubb/ultimatebb.cgi?ubb=get_topic&f=11&t=000911

I will be using chevy 3/4 ton D44 rotors about $35 each, 3/4 ton calipers $12 each plus $10 each core at Autozone. Then you will need various bolts, brake lines and the brackets which you can make yourself.

Okay here is the deal, the caliper plate in the first pic is made out of 3/8 plate, I used the stock caliper bolt slider thingys to mount the caliper, you have to tap the plate with a metric tap to bolt up right. I had to space the caliper plate out 1" from the backing plate mount bolts to get the proper alignment. These pics should get you started, I have to change the rear springs on Sunday, if you need a better pic let me know I can take some.

Hope this helps..

I think it is a 11 mm tap, just go to you local hardware store and they can fix you up. The bolt that you will be getting is about 3" long with a 2.5" sleave over it for the caliper to slide on about 5 bucks a piece, bring is find a nut that will screw on it and get the correct tap.

Tapping the holes correctly (ie. Straight) is critical, I had one go through crooked and the caliper would bind.

Good Luck

While I am always down for a little custom fabrication, no one knows of a kit you can buy from like SS brakes or anything? I am sure it would cost you an arm and a leg, but I guess I am amazed no one sells a kit. Some times these kits can be cheep ... some times. Seams to depend on the demand. Any thing for dana 44, 35, 30 or a nine inch seam to be expensive because they are common. 14 bolts don't have a huge after market. <IMG SRC="smilies/beer.gif" border="0">

Try The Street Rod Mfg Co (TSM corp) you can buy just the brackets for under $300.00 than you can use GM Truck 1/2-3/4 ton calipers (same thing) or get Eldorado rear calipers that allow you to use e-brake cables. I've done this swap a # of times...you can e-mail me if you need any info <IMG SRC="smilies/usa.gif" border="0"> <IMG SRC="smilies/usa.gif" border="0">

Since the company was recommended but no contact info was provided, here it is. I'm sure somebody would have asked. TSM's phone number is (303)688-6882. They don't have a website.

Thanks for all of the info.
I just picked up my 14 bolt today.
It was out of an 80s dually Chasis cab, 64" wms-wms, Damn those drum brakes are huge, I just about busted a nut hefting that thing into my Ford with another buddy.
Do you think it might be possible for one of you guys who have made your brackets, or even Pyro with TSM version, to trace the pattern and fax it. What can I say, nothing like getting a template from an already successfull fabrication. If not how about some detailed dimensions. im gonna start swapping this thing tomorrow, and would like to have it complete for the clean up run next weekend.
Thanks

If someone does this can I get in on it too as I am going to do the same swap soon and it would be nice to not have to design and find all the measurements. Thanks.
