Switching to discs is the biggest brake upgrade you can make. This Kodiak 13" disc brake kit fits 7,000-lb axles and delivers shorter stopping distance and more consistent braking than drum setups. The Dacromet-plated cast iron rotors, calipers, and brackets fight corrosion in freshwater or saltwater use with a 300- to 400-hour salt-spray rating. You’ll feel the difference in smooth, even braking at highway speeds and lower maintenance over time thanks to fewer moving parts.
If you like doing your own trailer work, these slip-on rotors make the upgrade simple. They fit over standard idler hubs and are held in place by your wheel and wheel bolts—no need to replace the hub. Each rotor removes easily for service, so you can repair or replace parts without junking the whole assembly. Installation adds only about 1/2" of track width from hub face to hub face.
Long grades and heavy loads create heat, but the vented rotor design keeps temperatures down to prevent fade or damage. Cast iron calipers resist flexing for more braking torque and even pad wear, while the low-drag setup retracts the piston farther for cooler, smoother operation. The stainless steel piston is 2-1/4" in diameter—30 percent larger than others—for higher braking torque and shorter stops.
The included ductile iron mounting brackets are made for 5-bolt brake flanges and feature a side-support design that puts the load on the bracket instead of the bolts. Extra embossing gives more thread contact for secure caliper mounting. That means solid, rattle-free braking performance every time you hit the pedal.
Everything you need for one axle comes in the box—two Dacromet-plated rotors, two calipers, two ductile iron mounting brackets, and four stainless caliper bolts. The kit works with 16" and larger wheels and an 8 on 6-1/2" bolt pattern with 9/16" wheel bolts. It’s covered by a 3-year warranty and requires a hydraulic actuator rated at least 1,500 psi (sold separately).

Speaker 1: Today we're going to be taking a look at the Kodiak line of Disc Brake Kits. Now, these kits are available in multiple configurations to fit multiple size axles. They're also available in several different finishes.A disc brake kit like this one from Kodiak is an excellent solution to give us good braking force. Typically, for this kit anyway, you're looking at like a 3500-pound axle. A lot of boat applications, you're hauling a boat sometimes miles and miles and miles, and without brakes on your trailer, you put a lot of unnecessary stress and strain on your truck. A braking kit like this allows us to take the stress, the strain off the braking system on our truck but also gives us a safer ride.In this application we've got a surge coupler at the front of the trailer, so as the truck slows it applies the hydraulic fluid pressure, squeezing our caliper together giving us excellent stopping abilities.
The rotors, calipers, and the ceramic pads are all automotive grade, so they're going to be made to the highest standards being sure we get excellent braking capabilities.Now when we compare a disc brake kit like this to a hydraulic drum-style brake, there are several advantages. Of course, we all know disc brakes tend to work better than drum brakes. They lock up less. We typically don't have the moisture being held inside. Especially in a marine application, that hub fills up with water, that moisture stays inside, causes some corrosion issues.
In this situation, once we bring these out of the water, everything's going to drain away. Air can get to it very readily and dry everything up.Another advantage we're going to get with this particular kit over the other disc brake kits available, the material composition is very corrosion-resistant. Our rotor, caliper, all stainless steel, plus they take that a step further, put a Dacramet finish all the way around. So that's going to work out really well, especially in a marine application like this, but also just on a utility trailer, keeping everything nice, corrosion-free. It's also going to be an excellent, excellent choice if you use it in a saltwater-type application.Something else you'll notice, pretty common on automobile applications, not usually on trailers, is going to be the ventilated rotor here.
So you've got two wear surfaces here and here. Those are going to be separated to allow air to flow freely in there and get everything cooled off to give us premium braking performance every time we hit those brakes.All right. With the bracket installed, we can move onto installing our rotor. That's one of the big benefits I like about this kit. You don't have the whole disc with the hub assembly in it.
So if you ever need to replace the disc, you're just replacing the disc, not your entire hub. This is going to fit right on our idler hub just like that, very common on automobile applications. They call this more like a top hat rotor where it it slides over your lugs, and then your wheel is actually going to hold that in and flush.Next, we'll move on to getting our caliper installed. Now the calipers can go either side. You don't have to have a left and a right. You can see we've got a bleeder screw on both sides. We want, of course, for our hydraulic connection to be facing in. Our slide bolts are going to come in this way just like that, and then these two portions are going to go on the back side of our bracket. So we slide that over, bring it in, and then we'll just push our bolts in, line them up with our holes and get them started. Now those do have loctite on them, so you'll just get them started a little bit, and then we'll use a 13mm socket and snug them on down.Now that we've got those snugged down, we'll use our torque wrench and we're going to torque them down to the specifications listed in the instructions. With our brake assemblies in place, it's time at this point to install our tire back on. Now, we do recommend using a torque wrench and torquing these down properly per the 1/2" stud application. Something we've seen, especially in the automobile industry, if you tighten these lug nuts down too much, you might cause that rotor to warp a little, decreasing your performance. That's going to complete our look at the Kodiak line of Disc Brake Kits.

I want to thank you again for your assistance in getting me the correct parts for my trailer brake installation. I took three major road trips with the boat last year and the trailer brakes worked flawlessly. The major reasons I installed the braking system were: the overall weight of the boat and trailer in relationship to my pickup 2006 F150 and braking performancesafety on wetslick roads. Both of these concerns were tested last year with wonderful results. I have been telling my friends, with similar trailer packages, to investigate your product. Thanks again,

They are still excellent in performance and quality.

Been a year, brakes are so responsive and work so much better will never rely on the old way further. Still working great, never any problem and have never experienced any fade. Switch now and enjoy the added safety.

Sorry about that. I will see if I can get that added to the page to make it clear. Typically the bolts from the previous brakes are used to install the brackets, but it should be made clear that they aren't included with the new parts. What kind of trailer did you install these on?

Disc brake installation went smooth and easy. It would have been better to have the adapter plate mounting hardware. One think to note about these Kodiak disc brakes, the bleeder valve is a two part valve. Be sure to open the 516 hex bleeder screw and not the 38 screw in bushingseat.

Slide pins fall out. Apply extra loctite when installing. Otherwise still working good.

The brakes have been troublefree and make a huge improvement in highway and mountain driving
