I'm Ryan from ExtremeTerrain.com, and this is my review of the Teraflex Big Brake Kit, fitting all 2007 and up JKs. This kit is available with the slotted rotors that you see here, or with plain rotors for a few dollars less. Today, we're going to talk through the installation of this kit, which is a very simple one out of three wrenches. This is something that you can get done in your driveway in under two hours. There's no major modification necessary to install this big brake kit. We're also going to talk through the construction and a few of the features of the kit. This is for those of you who are running big, heavy wheels and tires on your Jeep and want some additional stopping power. Now, you can always upgrade to a high-quality rotor and pad that will give you some additional bite, and you can also upgrade to a larger rotor that simply has a bracket to move the caliper away and mount it in a proper mounting location for that larger rotor. But, this kit includes not only large slotted rotors, but also pads that are designed to bite really well into those rotors, and not just brackets to move your factory calipers, but new aftermarket calipers that are twin-piston calipers. These are going to create a ton of additional clamping force that is really going to be noticeable when stopping your Jeep. Now, again, there are a lot of different ways to upgrade your brake system. This is really the all-in way to do it. Between the larger rotors, the larger twin-piston calipers, the pads, this really does include everything, so this kit is going to be expensive. Now, not as expensive as some of the other kits on the market, but this is going to be a pricier way of upgrading your brakes. If you're just looking for a little bit of additional bite, you can certainly go with one of those other systems that doesn't include all of these components and have a little bit better performance, but if you're looking for even more, this is a great way to go. As I said before, this kit really does include everything you need to upgrade to a big brake kit on your JK. It has, of course, these new rotors, and, again, these are available slotted, or plain for a few dollars less, and these are 13.3 inches, which is an upgrade over the factory which are around 12.5 inches. Now, because these are larger and because these calipers are larger, you are going to have to run at least a 17-inch wheel to fit these big brakes underneath of it, but if you do have a large wheel, these are going to clear without any other major modifications. Now, to go with your new rotors, of course, you have a new set of pads up front, but really, the star of the show is these new calipers. These are twin-piston calipers, and each one of those pistons is 56 millimeters. This is going to create a ton of clamping force on these new rotors, really helping to stop the Jeep quickly, even with big heavy wheels and tires on it. And, of course, you have your caliper brackets to make mounting your new calipers with your new, larger rotors onto your Jeep a very easy process without any major modifications. Even though this kit does include quite a few components and you are giving yourself a lot more braking power, the installation is really not that much more difficult than doing a traditional brake job. The first step in the install is going to be removing the wheels, of course. Then, you can unbolt your calipers, your caliper brackets, and get rid of your rotors. From there, it's just a matter of installing your new rotors, your new caliper brackets and calipers with the new pads installed in them, and bleeding out the new brake system. As Teraflex will tell you, breaking loose the banjo bolt on your old calipers before unbolting the calipers from the brackets will make that process a lot simpler for you. Of course, as I said, because you are opening up the brake system when you're installing new calipers, you are going to have to bleed the system out, but that's not something that is a huge deal to do. That is really a general maintenance item. You are going to want to bleed your system from time to time to get rid of the old fluid because it does absorb water from the air, so that isn't something that should keep you from installing this system. Overall, a very easy install at one out of three wrenches, no specialty tools necessary to get it done, just your traditional hand tools, but make sure you have some brake fluid on hand in order to bleed the system out and get everything up and running when you're finished. Once you do have everything installed, you will want to go through the break-in procedure that Teraflex will tell you about to ensure that you get friction material from the pads onto your new rotors and make sure that everything is going to work really well, as it's designed to. Now, as we said before, there are a couple of different ways to upgrade your brakes, from just swapping out the rotors and the pads, to going to a bigger rotor with a caliper bracket, to a system like this that has calipers, caliper brackets, larger rotors, and pads. And this system, because it does have all the components, is going to be one of the more expensive options when you're talking about upgrading your brakes. However, there are some brands out there, like the Baer brake systems, that will have some additional features that are going to be even more expensive than this system. So, all in all, if you're looking for a big brake system that includes a dual-piston caliper, this is one that isn't quite as expensive as some of the others and is still definitely going to get the job done. However, if you don't have the budget for this system, or you're not quite looking for the stopping power that it provides, you can still upgrade to these same 13.3-inch brake rotors with caliper brackets to relocate your factory brake calipers for about half the cost of this system. So, if you're looking to add a ton of braking power to your JK by upgrading to a larger brake rotor and a twin-piston caliper, this is going to be a really nice system. This is well put together, so everything is going to work in conjunction with each other, giving you a lot of stopping power, all without being at the very top of the price range. So, that's my review of the Teraflex Big Brake Kit, available for all 2007 and up JKs, that you can find right here at ExtremeTerrain.com.

So far they're no big improvement over stock. I was expecting much more. I will review at 500 miles and see if they're any better .

Noticeable braking improvement
I saw definite reduction in braking with stock brakes after I added 35" tires and a few hundred pounds in weight. I just installed the Big Brake kit today. Easy to install. I followed the recommended break in procedure. I will put a few more miles on the brakes to fully break them in before putting them to the test, but so far I am pleased.

Not so great yet
Well they say give them 250 miles for break-in, I'm in 450 miles and while the kit is definitely better than factory brakes on my 2017 jk unlimited, can not say yet it is worth the cost. May invest in rears too and will repost.
