How-To: Front Cobra disc brake conversion
How-To author: Dangerranger01
Original thread: https://www.ranger-forums.com/f59/ho...version-98833/
Let the modding Begin!!
_________________________
***So because so many hosers can't search and see for themselves what is involved in a COBRA front disc brake swap, i've complied these pictures and notes for such a thing....Enjoy!!!
This 'How To' is to put COBRA front disc brake onto a RANGER. The COBRA has 13inch rotors with large piston calipers. This setup is a MAJOR improvement to the stock RANGER disc brakes up front.
This conversion is only for 2wd, coil sprung RANGERs. This set up will NOT work for EDGE for 4wd Rangers.
Step 1: Obtain the out of production kit from some dude in Canada.:
Step 2: Take off old front brakes, and bolt on modified front hub:
Step 3: Slide on front rotors and bolt on new Caliper:
Step 4: Bleed brakes, bleed in new rotors and pads, and enjoy new big brake kit!!!!:
***I went with Stainless Steel braided lines because it is badass and the most highest performance i could do when doing this swap.
And you're done!!!

I didn't do the Cobra Conversion - but I did put 12 inch Sport-Trac rotors on my '96 this afternoon. I made the adapters ahead of time, and took 5 hours to install them. I flattened the dust shields so they could fit. and had to grind the front 4mm bolt (8mm head) to provide clearance. The stock caliper bolts were NOT useable, contrary to what previous instructions stated, and I had to grind both the caliper frame AND the knuckles.
It sure stops a lot better now (have 225/70-16 tires/wheels)

I made spacers from 3/8X2 CRS with 2 sets of holes to match the bolt pattern of the caliper mounting frames, .875" apart, with d shaped spacers the thickness of the knuckle where the caliper frame attaches welded to the one set of holes (drilled, of course to fit the new 12mm bolts), and bolted the adapter to the knuckle, and the caliper mounting frame to the adapters. Took some grinding on both the knuckle and the caliper frame to provide clearance to align the bolts. Needed a set of small head high strength bolts to fasten the adapters to the knuckles, and caliper frame mounting bolts 3/8" or 10mm longer than stock to fasten the caliper frames to the adapters.

I was able to confirm this from another site.... They are ranger brakes machined down to the hub. Adding the cobra rotor to the outside of this will add about 1/4" to the track width. Here is a link to a company that sells bolt on kits. Ford Ranger - Kits

I actually just replaced my brake rotors yesterday as they were due along with a noisy wheel bearing. I think I'm going to save the rotors and have them machined down. I already have 17" wheels, so that's not a problem.

I have not yet completed this as I have been working on other things on the truck. I plan to tackle this soon though. I will be machining the hub down, using a 13" cobra rotor and ATS brembo brakes. The ATS brakes are fairly cheap and can be found easily. Obviously, I will have to design/machine a bracket but that wont be hard. I will post some photos when I start the project.

Thanks for the update. Good luck with the truck. I look forward to seeing your progress.
