      Review & Installation Video

      I'm Ryan from, and this is my review of the G2 Disc Brake Conversion Kit, fitting all 1990 to 2006 Wranglers. Today, we're gonna talk through the installation of this kit, which I am going to give a strong two out of three wrenches. There is no major modification of the Jeep, no drilling or cutting necessary in order to get this kit installed. However, there is a good bit of disassembly of your axle to do in order to get this bolted up. So again, a two out of three wrenches, and this is going to probably take a little over two hours, maybe even a little bit closer to three. We'll talk a little bit more about the install in a moment. We're also gonna talk through the construction and a few of the features of this kit. A kit like this is going to provide some additional stopping power. However, the vast majority of the stopping power on your Jeep comes from the front brakes, as with most other cars, so you're not going to get a drastic change in braking performance by installing a kit like this. However, there are still a few reasons to install this kit, even outside of the braking performance. One is that a disc brake kit is a lot easier to maintain than drum brakes are. If you've ever installed drum brakes or changed drum brakes, you know that they can be a little bit of a pain to mess with. You have all of those springs. Everything has to come apart and be put back together in a very specific way. With these brakes, maintenance is going to be a lot easier. You can very easily change the pads and the caliper. You can even very easily change the rotor when it's time to do that. So maintenance is one big reason to install a kit like this.The other is that, if you do have a Dana 35 Rear Axle, that is a c-clip axle. And if you do a lot of off-roading, if you have a bigger tire, if there's a chance that you're going to break that axle, with a c-clip axle, when you break it, the whole wheel hub and tire assembly can sort of just walk off of the Jeep. Now, with a disc brake conversion like this, the caliper's actually gonna keep the tires and everything in place, so you will be able to limp at least off the trail. Now, that's certainly not a main reason to buy a disc brake conversion. However, it is a nice benefit. Now, there are a couple of different disc brake conversions on the market. Most of them are gonna be right around this price. I think that this one is really well put together, and I think it is fairly priced. Although one thing to note with this kit, because it does work on a couple of different generations of Jeep, you are going to have to purchase your emergency brake cable setup separately. You get pretty much everything you need included in this kit, barring that emergency brake cable that I just mentioned. This is going to come with the backing plate that has a drum-style, internal emergency brake, which is going to do a really nice job of holding, even compared to your emergency brake that's on your existing drum brake. These tend to work very, very well. They have a self-adjuster built into 'em. That's built right into the backing plate here. Of course, you have your new caliper bracket that's included as well, your caliper with a couple of brake pads. You can see the caliper isn't huge. Again, you're not getting a ton of braking power from the back of the Jeep. However, this is going to give you all of the braking power that you need. It is going to be better at stopping the Jeep than those factory drum brakes will be. And like I said before, you do have those other benefits. And finally, this does come with, of course, the discs themselves, and these are a slotted disc. They are a centric disc made by Power Stop. I run a version of these for the front on my TJ, and combined with the right pad, these have a ton of stopping power. So overall, a very nice kit. It also comes with, of course, the rest of the hardware that you're going to need to get these installed. It comes with your new

        Best upgrade by far

        Very straight forward install. You can totally knock it out in 3-4 hours while doing new bearings and seals. My stopping distance feels like half of what it was with the drums. Well worth the money.

        Can’t really review this yet, let me tell you why

        Haven’t installed it yet. Extreme Terrain doesn’t stock everything you’ll need. Still waiting on the required parking brake cables from a second source. Extreme Terrain was able to get the part numbers for me, ehich waa nice. Also, no mention is made in the instructions about how to make sure there isn’t pressure on the line to the brakes when they are not applied. That is a feature of drum brakes, and if not disabled will cause brakes to drag and heat up, or lock.

        Dont get this if you want a bolt on kit

        You have to completely remove axles which is fine... but you WILL have to get the old bearings, seals, and retainer removed by a machine shop. THEN, have them intall the new hardware with a hydrolic press. Next, you will need to find new hard brake lines for the E brake. It will need to be for 00’s and later models. I got my lines from an 03’ because the end fitting is different than my model.

        Better brakes less headache

        My mechanic in Costa Rica installed this on our TJ down there. This was no issue since he did it with the English instructions and he only speaks Spanish. His only issue had to do with some corroded parts that were hard to remove (changed seals and rear bearings at the same time), but other than that it was straight forward. Brakes work much better on the hilly terrain of CR. A 22mile trip to the beach takes an hour if your lucky between the tight curves and intense grades, and that is on a paved road. A few days before I arrived with the G2 conversion parts my son had an issue with the drums. Now that should be a thing of the past.

        Quality parts, Easy install

        The parts are quality. The instructions included were sufficient for a rookie like me to follow and complete the install. I noticed an increase in braking power.

        Disc brakes

        Everything worked great minus the the e-brake cables. It took a bit to get the cable to stay clipped into there mount. Other than that no complaints.

        missing hardware

        Missing brake cables for the parking brake. if I was told I had to get them separately it would be a different story or they sold them with the kit.

      Hi, does this kit come with the parking brake cable? If not do you stock that and how much would it be extra? Thanks, Tim

      • The G2 Disc Brake Conversion Kit does not come with a parking brake cable. You will need to get an upgraded parking brake cable when installing this kit.

      Hello, I have two further questions. Do you carry replacement pads for G2 Axle And Gear 96-2049-DB Axle Shaft Rear, and does the current emergency brake cables hook up with this conversion unit. Could not find out this info anywhere.

      • The factory emergency brake cables will not work with this conversion. The G2 Disc Brake Conversion Kit will utilize OEM 2003-2006 TJ rear rotors and pads.

      Do you know if this kit will work with 15 inch rims? Or do I need a larger rims?

      I have an 89 yj. Is there a difference between the 89 to 90 yj? Or would this kit work on my Wrangler?

      • The G2 Disc Brake Conversion Kit only works with 1990-06 models, it will not work with your 1989 Wrangler. It works with only 1990 and newer due to the Dana 35 C-clip axle that is found only in 1990 and up.

      What master cylinder and proportion valve do I need? FYI. I installed a rear disc kit from crown. Larger double diagram booster and a disc/disc proportion valve. Tried a 1 1/8 master cylinder. Still can't stop with 35 inch tires.
