I assisted her with the installation, was an utter piece 'o cake. I have the Teraflex BBK and the larger Master Cylinder. The performance of the BR6 on her rig, which is on 35s vs mine on 37s, was comparable and a major improvement over the stock configuration. She ordered the BR6 master, but we didn't install it as the brake performance was excellent without the changeover. The BR6 caliper is similar, but the caliper support is different and prvents using the stock one. Pads look differet, but stock pads will fit the BR6 caliper . (Used on Dodge Nitro.) Essentially, Jeep just uses a larger rotor and moves the same caliper outward to increase braking leverage,. Similar approach is taken by Teraflex on their "Big Rotor" kit, and aparently by Dynatrac on their new setup. Jeep should just put the BR6 parts on the JK at the factory and be done with it.

That's probably from the thread I started over on another site. One of my club members did this conversion and we documented it. She searched all the Forums, collected the part numbers, determined most are used on other Mopar products and ordered them accordingly out of a dealer in Texas. What she learned was if she tried to order these and said she had a JK, the order would be cancelled. If the parts were ordered for a Dodge Nitro, etc., the order went through and they shipped the parts.

Im in the same boat at my 13 has 35k miles with 35s. I had to do a "panic" stop yesterday and it was horrible. I had both feet on the Pedal and it just kinda came to a stop. I really want all new brakes and calipers. I'm not even sure where to start. My 392 Challenger has Brembos and they will literally throw you through the windshield but I think they are very expensive for the JK.

With my 35s, yes. I had to make a quick stop from 60 MPH when a yellow came on just a second too early for me to go through. The nose dove deeper than stock and I had plenty of room to spare before reaching the intersection. It would have been tight with the stock brakes.
I went with the Mopar pads listed in the parts list. Rear is still all stock. I know Crown makes a stock equivalent to the part number for the rotors in the parts list. However, they measure 13" and not 13.25" but still work.
That's a scary situation with big tires and heavy armor. That's why I upgraded right after getting my wheels.
What pads did you end up with? Did you swap your rear pads too, as that seems to me the extent of a rear upgrade. I looked again and the rotors I was looking at were Omix-Ada, I know they're an OEM manufacturer but their description does not give the rotor diameter; 13.25" or 13"?

I heard that slotted (and/or drilled) ones aren't good for mud. Not sure if that's a factor for you or even if it's true but that's what I heard.

Thank you for pointing that out. Mud isn't much of a concern for me but I'm sure it is for other members. I've heard the same thing about slotted/drilled rotors too.

Mud is soil grains and water. The grains are not soluble, are pretty hard, and can easily scratch the disc.
Dry grains fly off, mud sticks.
Slots or holes allow mud to get inside, where there's supposed to be free air flow. Removing dry mud from in there, is an unnecessary burden.
Sooner or later, even in dry regions, we cross some mud.
