Same along with the upgraded brake master cylinder and I did the teraflex rear big brake kit when I swapped in my rear CRD60 axle. Night and day difference over factory brakes.
I went with the Teraflex big rotor kit, and it's been great. It beefs up the pads and rotors but leaves the stock hydraulics. It made it an easy kit to install and it made a decent difference. Highly recommend.
I went with the MOPAR BBK up front and the Teraflex kit on the rear.
MOPAR BBK: bigger booster, master cyl, discs & dual piston calipers up front
Teraflex: bigger discs but same OEM calipers & pads
I pull a mil-surplus trailer.
I like the added braking power over the stock setup.
I got the Dynatrac big brake (rotors) kit because I wanted to improve both the front and rear, since the rear wears out so much quicker. And I didn't want to have to mess with the master cylinder or bleeding them.
Bedded them per instructions and they work awesome, stops very quick now. I can lock them up really easily if I want to. After putting in the Rubi t case it was nearly impossible to stop when going downhill in 4 low, but no problems now. I also pull and 2700 lb camper (dry weight) and didn't even notice when the trailer brakes went out on me once. For the record I'm on 37s with 4.56 gears.

I find that when going down hill with my Rubi's, placing the auto trans in 'N' saves a LOT on the amount I have to push on the pedal and in turn, how much brakes I wear out. That LOW LOW 4:1 transfer case is great going up hills but murder on brakes going down.
I also went with the Dynatrac kit. It is working great so far.
The main advantage to big brake kits is in the larger diameter rotors. That moves the contact point of the brake pads further out from the center of rotation, which increases the leverage the brakes have on stopping the rotor (and you). A second aspect is the larger diameter rotor has more mass and as such takes more heat to raise the temp of the rotor a given amount.
Kits that replace the calipers and / or master cylinders can offer a small amount more in braking improvement, but they can also change the feel of the brakes (not always for the better). Plus they are more expensive and more work to install.
I was torn between the TeraFlex kit(s) and the Dynatrac kit. I like that the Dynatrac kit is a one complete kit deal. And the quality of the kit seems top notch. I'm sure there are other good options, but I had no need for a kit that replaced the calipers (the stock calipers work fine) unless I was going to step up to an opposed piston caliper set up. And for that the price tag is way high. And putting all that work and money into a new caliper that is still a single sided caliper did not seem worth it to me. Running 37's really demanded better brakes. The Dynatrac kit resolved that issue for me.
I have the Teraflex front big brake kit with slotted rotors. Stopping is great. On warm days I do get a vibration coming from them, I was told it’s because of the slotted rotors. Drives me nuts? Lol
I added the Teraflex larger rotors and caliper relocation brackets to the front after I went to 35's. Braking seems to be about the same as the stock setup with 32's, which is much better than the stock rotors with the 35's, so I do not have any plans to add a different master cylinder or calipers, or do anything to the rears.
Only speculation, but IMO 37's would probably be better off with the larger rotors paired with the Ram 1 ton calipers.
No need for different calipers....have you seen the size of those? And the rear brakes on bbk's are larger than the fronts so you should consider it since wranglers use ALOT of rear braking....
The Dynatrac kit is awesome. Running 37's the stock brakes were pretty horrible, put the Dynatrac in after reading a lot of reviews and I am super impressed by how easy the install was and how well they stop. Way better than stock on stock wheels.
I went with the Teraflex kit because at the time, that was really the only off the shelf kit available. Larger rotor in front, larger caliper, upgraded master cylinder. In the back, larger rotor and a caliper bracket to move the stock caliper out. It’s worked well for me for probably 6 or so years now.
If I were to make the mod today, I’d probably go with the Dynatrac kit because it’s cheaper and simpler. It uses the stock calipers and so doesn’t require any bleeding or changes to the master cylinder. You can also use stock pads once the Dynatrac pads wear out.
In any case, certainly for 37s, or even a JKU on 35s, I’d definitely recommend some kind of big brake kit.
I also got the Dynatrac system for the ease of installation and no messing around with the bleeding etc. I’m running mine on 33” with plans of lift and possibly bigger tires in the near future. What a difference in the braking! Stops on a dime! Took it on recent road trip loaded down with roof rack and a huge Akita (our road dog) and it performed like a champ. Very happy with this system.
Thanks to everyone for this potentially lifesaving thread. Better brakes is something I desperately need. I'm running 35 M/Ts on my 2014 Wrangler. On the skid pad, mine currently stops from 70 mph to 0 in about 2 hours. Maybe three if the wind is at my back. Scary!
One more for the Dynatrac kit. I would have done the Mopar kit but I have a compressor in the engine bay so no room for the larger master cylinder/booster.
As others said, the Dynatrac kit is awesome and it’s a bit easier to install than the Mopar but, really, I haven’t heard anything bad about Teraflex or Crown so it sure you can go wrong.

A few questions for those who have installed Dynatrac:
1. Did you install fronts only or front and back?
2. Does the Dynatrac kit use OEM pads or special pads you need to source from Dynatrac?
3. How long do the pads last?
Easy install and good stopping power for my 37s on Beadlock KMC Machete Crawlers installed. Great value.
Original pads wear out quickly though, about 10k miles.
Last night I ordered the Dynatrac ProGrip Brake Upgrade System. There have been several times on the freeway I've had to swerve out of my lane to avoid hitting someone who stopped faster than I could stop. Not good. Not good at all. Really looking forward to this upgrade. I chose Dynatrac because they have a strong reputation for quality, confident reviews, great price, easy installation, and several installation videos. So all things considered, I went with them. Thanks to all.
Before I went with my BBK, the best thing I did was change stock rear pads, which had worn out, with Hawk LTS pads. Amazing stopping and feeling with just that small change.
Still not what I fully wanted, so I went with Teraflex front (only) BBK. Again, much better, and together with rear Hawk pads, made braking good. However, I was still not happy with the pedal "mush".
Last, I got the J8 master/booster, and changed front pads to Hawk LTS, as well.
Solid pedal, intense braking, no doubt brakes are being applied. Significantly better than any other JK (or JL for that matter) than I've driven. Was going to get rear Teraflex BBK, but decided to hold off, for now, as I don't see any immediate need.
As far as I know, the Dynatrac kit come in two flavors, rear only and front and rear.
The rear only kit is just over $600 and the front and rear kit is just over $1,000.
I think I bought mine from Quadratec. But Northridge is another possibility. Both will give you a discount on the price for being a forum member. (with NR 4x4 try putting wranglerforum in the coupon field in your cart, I wish Quadratec had it so simple)
Another option is a small independent shop like AOR (Allens Off Road) or KOR (Krawl Off Road). Both of them are good folks to deal with and both of them also will typically give you a discount for being a forum member. Lately I have bought a few things from Jason and Austin @KOR. In part because I like supporting the independent shops, but also because they gave me a great price and they are located in the same side of the country I am on. I would happily buy from Allen, but he is on the other side of the country from me. I guess in the end that probably doesn't matter, but sometimes it does.
I have Dynatrac's ProGrip 2 kit and I love it. Its a team up between StopTech and Dynatrac and puts a 6 piston caliper up front and 4 piston rear w/ bigger rotors and better pads. Also, did the J8 brake booster upgrade since the pedal would nearly hit the floor while stopping, much better pedal feel after the upgraded system.
Night and day difference between the factory brakes and the ProGrip 2. I also swapped a rubi case in and have absolutely no issues stopping while in 4Lo. The main reason I went to a big brake system was driving in SoCal traffic and stupid drivers that like to cut off big trucks and then slam on their brakes https://www.dynatrac.com/blog/new-d...mance-for-2007-and-newer-jeep-wranglers/

I just installed mine yesterday and I’m very pleased what a difference! However at low speed and lighter pressure I have squeak. I didn’t install the included shims...should I ?
Anyone else get squeaking? I’m guessing it will go away but it’s annoying
Yes, without the shims brakes will squeak. That's exactly what they are for—to prevent squeaking. You can bet if they weren't necessary, they would not have been included in your kit. I know because I also left them out the first time I did a brake job on my own car decades ago. They seemed superfluous. They were not, lol.
I went with the Teraflex BBK w/ non-slotted rotors. Since I use my Jeep offroad I didn't want to risk debris getting stuck in my rotors. I have the older non-Delta kit from Teraflex. I did front and rear. Very happy for over 20k miles.
My issue with that kit is that there are no replacement front calipers. The stock calipers are a single-piston design and IMO, they're anemic. The Teraflex kit, which would be about $300 more, comes with new front calipers which have a dual piston. Much better performance.
There is nothing wrong with the stock front calipers. The stock brakes actually work well until you start upgrading to larger heavier wheels and tires.
You can try the G2 kit. But in my opinion brakes aren’t the place to try to save money. The Dynatrac kit is proven to work great. G2 is a more budget friendly brand, but not as geared towards quality.
Just ordered the Dynatrac kit from NorthRidge, using the forum discount!
