Ok. So I don't post much here, but here's the situation. Putting '79 Bronco Axles under my '99 Ranger. I want to run Discs on the rear because... well quite frankly, I hate drums with a passion. So I'm in the process of working through how I'm going to get this done on my 9" other then spending $1100 to get SSBC's kit.

http://www.stainlesssteelbrakes.com/products/detail/2361/?make=Ford&model=Bronco&year=1979

Well after some searching I came across this site.

http://steeltechsolutions.com/REAR_DISC_PAGE_CODE.html

Appears to be a decently legit site (not really up-to-date or anything), but for $500 bucks doesn't seem like that bad of option for Calipers, Rotors, Brackets, and Hardware.

Then I found the kit at BroncoGraveyard.com.

http://broncograveyard.com/bronco/i-22335_9inch_1979-86_disc_brake_conv__3_8_studs.htm

However, that doesn't have Calipers or E-Brake Setup. So with careful shopping you could probably pull it off for under $400, but more then likely close to the steeltechsolutions kit.

However, I decided to see if I could still do this cheaper (yeah I know I should quit pushing my luck since it is my brakes after all). So I started looking into just getting parts and trying to assemble it myself.

Here's what I've found so far doing that.

http://bluetorchfab.com/store/product_info.php?cPath=24&products_id=91

BTF fab bracket that supposedly fits a 9" no problem and can mount older 3/4 Ton GM calipers. ($50)

http://www.napaonline.com/MasterPag...liper+w/+Pads+&+Hardware+-+Left+Front+-+Remfd
http://www.napaonline.com/MasterPag...iper+w/+Pads+&+Hardware+-+Right+Front+-+Remfd

'75 3/4 Ton GM Front Calipers and Pads with Hardware ($110)

http://www.napaonline.com/MasterPag...escription=Brake+Rotor+Only+-+Front+-+Premium

'75 3/4 Ton GM Front Rotors ($85)

However, can you just re-drill that '75 GM Rotor to a 5x5.5 Bolt Pattern? I will still be running 5x5.5 pattern and I don't want to change (wheels are already purchased). And even if you can just drill those out, I would still need E-Brake setup and at that point your starting to run close to the costs of what BroncoGraveyard's kit runs.

Or is their a Caliper that will just fit a stock '79 Bronco front rotor that can be easily mounted to the 9"? I'd be more then willing to try and fab up my own bracket if necessary. Seems like that would be the easiest as then you wouldn't have to dick around with re-drilling anything. I mean just looking over the specs of each of the rotors (GM vs. D44 Rotor) on NAPA's site, and they are fairly different.

So I'm just curious what you guys think. Seems like there are quite a few options, but of course money is always a factor. Anyone use any of these kits (and/or fab up their own setup) and if so how does it work?

Let me know what you guys think and if you have any opinions on the matter. Maybe I'm just over-analyzing this, but when your low on funds and big on dreams, that is bound to happen. ;)

Also, sorry, I'm sure this has been covered to death, but I honestly did search but didn't see anything pertaining to 9" axles (saw a couple threads on 8.8" disc conversions). If their is a big write-up on this that I just missed, let me know and I'll go check it out.

Thanks for reading.

For an e-brake you need the caddy calipers.

BC Broncos stock the hardware kits. (Bolt on not weld on - weld on is cheaper).

Wow. I like their kit. $557 for everything... but that is everything including Brakes lines, and E-Brake Hardware. Thanks for telling me about them.

I used stock front Bronco rotors on my 9" rear disc, about $20 each new. You need a caliper that will work with a 1 1/8" thick rotor. If you can stand to use GM junk, you can get caliper brackets from any place that sells parts for I.M.C.A. modifieds. All the dirt racers run rear discs. Here is one place that sells them, http://www.afabcorp.com/AFCO_Dynatech_USbrake/merchant.mvc?Screen=PROD&Store_Code=A&Product_Code=40120&Category_Code=ct_bracket-brakes $14.95 for weld on brackets. I work at a racecar shop and we use Afco bolt-on caliper brackets, then weld the lower half to the axle tube. That way if you bend something, all you have to do is un-bolt one half and replace it. http://www.afabcorp.com/AFCO_Dynatech_USbrake/merchant.mvc?Screen=PROD&Store_Code=A&Product_Code=40120C&Category_Code=ct_bracket-brakes This link shows the bolt-on style, $58.50. I used this style caliper for my set-up, 4-piston billet aluminum.

Ther are more pics on my Supermotors page.

I got the BC Bronco kit(master kit+calipers)

http://www.bcbroncos.com/info.html

I was very happy with the quality of the product and ease of installing the kit. I would recommend a new proportioning value and getting rid of the stock one. If you can upgrade the Ranger master cylinder and brake booster easily, I would highly recommend that. The prop valve and F-350 MC/booster really improved my braking.

Bronkster.... you have a link for those DRT calipers? I tried googling DRT brakes but didn't come up with anything so I was curious what company they came from.

Not saying I'd go with Billet Calipers, just curious is all.

You could use the explorer rear disc setup, The parking brake is inside the rotor, It uses shoes for the parking brake. You would have to use torino style ends on your 9" though, I have the BC broncos kit on my EB. Very nice kit, But I'm into it for about $600 with the caddy calipers

Hey Scott, have you started your disc set-up yet?
No :brownbag not on either one. It don't help not having the Bronco here plus doing the shortbed and the 350 I have been pretty busy. Maybe once the weather breaks and I sell the 350 I'll start the swap on the 250 then the Bronco.

Which prop valve did you use? I have the same kit on my 78 and the pedal is real hard. Still stops ok but you need some muscle to push the brakes.
