Features to know about

Upgrade from Drum to Disc: 13" Hub-and-Rotor Assembly for 7,000-lb Axles

If your old drum brakes are dragging or fading, this Kodiak disc brake kit is a major step up. Each 13" Dacromet-coated hub-and-rotor assembly delivers strong, consistent braking and much shorter stopping distances. The kit fits #42 spindles with 8 on 6-1/2" bolt patterns and includes inner (25580) and outer (02475) bearings, races, seals, oil caps, wheel bolts, and lug nuts—all ready to mount for one axle. Ceramic pads and a large cast iron piston give smooth, confident braking every time.

Built for Corrosive Conditions: Dacromet Coating Resists Rust

Saltwater, slush, and coastal air can destroy unprotected brake parts fast. These Dacromet-plated components—hub-and-rotors, calipers, and brackets—stand up to 300 to 400 hours of continual salt spray before corrosion begins. That means reliable braking even after repeated launches or winter road exposure. The 1-piece cast hub-and-rotor design also seals out water and debris that can cause uneven wear or contamination.

Keeps Cool Under Load: Vented Rotors Dissipate Heat

Long grades and heavy towing can push brakes to the limit. Kodiak’s vented rotor design moves air through the rotor to shed heat quickly, reducing brake fade and pad wear. The result is steady braking performance even after repeated stops on downhill runs or in stop-and-go traffic.

Saves Time and Maintenance: Simplified Disc Design

Disc brakes have fewer parts than drum systems—no springs, magnets, or cables to adjust or replace—so maintenance is easier and less frequent. The caliper is mounted outside the assembly for quick pad changes without removing the whole hub. With fewer wear points and pre-assembled components, this kit keeps you on the road instead of under the trailer.

Engineered for Long-Term Strength: Side-Support Bracket and 3-Year Warranty

Kodiak’s caliper mounting bracket uses a side-support design that carries load on the bracket rather than the bolts, extending hardware life and maintaining solid alignment. Combined with high-quality, automotive-grade materials and a 3-year warranty, these brakes are built to deliver lasting performance in tough towing conditions.

Video Transcript for Kodiak Disc Brakes-KOD73FR Spec Review

Hi there, I'm Michael with etrailer.com. Today we're gonna take a quick look at this Kodiak 13" Hub and Rotor Disc Brake Assembly Set. This is going to allow you to upgrade your trailer from drum brakes to disc brakes, so that you can take advantage of the superior performance that comes along with having disc brakes on your trailer. Or, if you already have disc brakes and you're just wanting to upgrade to a higher quality finish, these are gonna do a great job for you as well. Having the two brake assemblies is going to allow you to upgrade a single 7,000 pound capacity axle with a number 42 spindle. Our rotors are 13" in diameter and you can see, we've got the 5/8" diameter wheel bolts here and the 8 on 6-1/2" bolt pattern.

So these are gonna work for your wheels that are 16" and larger. Our hubs and rotors, as well as our calipers and our caliper mounting brackets, all have the Dacromet finish. So they are going to offer excellent rust and corrosion resistance with a 300 to 400 hour salt spray rating. So these are gonna work great for your boat trailers, or trailers that are used in coastal areas, or heavily treated roads, where you're gonna have a lot of contact with salt and corrosive materials like that. If you're looking at your good, better, best, kind of scenario, Dacromet is near the top in my mind.

The only thing better than Dacromet is stainless steel construction, and those can be kind of pricey so if you are looking for a nice, high-quality finish for your system, it's gonna hold up really well, last you a long time, this is gonna be a great way to go. Definitely higher than your E-coat, or definitely above your uncoated surfaces. These will hold up well to those more corrosive environments. So upgrading your trailer from drum brakes to disc brakes is going to give you several different benefits. It's definitely going to help to dramatically shorten your stopping distance.

You've got these ceramic brake pads here that are going to increase your stopping power. There's also a large 2-1/2" diameter stainless steel piston that provides fast, responsive braking. So it is gonna provide a smoother, more controlled braking experience for you than you're used to experiencing with your drum brakes. It's gonna help keep your trailer from pushing and pulling, so definitely a huge improvement in performance. And in addition to that, you're also going to have less maintenance with this style, so it's going to save you time and money over the long run.

Having that one-piece hub-and-rotor assembly is gonna reduce the chance of uneven rotor wear. And here on the side, we do have a vented design. That's gonna help dissipate your heat faster, to help prevent premature brake pad wear. Now, your brake pads will wear down over time so you will need to replace those eventually, but it's a pretty straightforward replacement, pretty straightforward process, and that's really the only component that's going to need to be replaced. You're not gonna have springs and all sorts of other components like your drum brakes. And these are a high-quality automotive grade construction, so it is gonna be very long-lasting for you. It's gonna be very minimal maintenance that you'll need to do. But the one caveat with disc brakes is that they do require a higher line pressure than your drum brakes. So you're gonna need to make sure that you've got a hydraulic brake actuator and brake lines that are rated for 1500 PSI and higher. And that's gonna be kind of rare for your trailers that are set up for drum brakes, so you're probably gonna have to switch all that out, so it might take a bit of doing to get this all set up for your disc brakes. If you don't already have those hydraulic brake actuators and brake lines, we do sell them separately here at etrailer.com. Obviously, it's not included in this kit. So this kit isn't gonna be everything that you need but it is going to include the two Dacromet-plated, cast iron hub-and-rotor assemblies with the eight pre-installed 5/8" diameter wheel bolts on each. You're also going to get 16 of these 5/8" zinc-plated steel lug nuts that will hold your wheel in place. You'll get the two Dacromet-plated cast iron calipers, as well as the two Dacromet-plated ductile iron caliper mounting brackets. As you can see, these have the five bolt brake flange configuration so they are gonna fit very easily onto your axles with those five bolts. And I do wanna point out that I've got this mounted on top just for display purposes, for balance, but when you go to install it, it's actually gonna be mounted on the side. And that side support design puts all the weight on the mounting bracket instead of on your bolts, so it's gonna help your bolts last longer. You are gonna get four of these stainless steel caliper mounting bolts. Your inner and outer races are pre-installed. You're also gonna get your inner and outer bearings that will fit inside there. Make sure that everything is rotating smoothly. This system is lubricated with oil so you're gonna get your two oil seals for the inside, your two oil caps for the outside. Those will screw in place. Make sure you're not gonna get dirt and debris and that sort of thing in there. And you're also going to get one eight ounce bottle of synthetic bearing oil to make sure that everything's moving smoothly, all your bearings are functioning properly and whatnot. So this kit, like I said, it's gonna be great as an upgrade for your drum brakes or if you've got disc brakes already and you're wanting that Dacromet finish, so that they're gonna be longer lasting for you, and these are gonna do a great job for you. And that completes our look for today. Again, I'm Michael with etrailer.com. Thanks for watching.

Quality product and looks very well made. The team at etrailer did a super job of helping me get the right parts to convert my Karavan tandem boat trailer to disc brakes.

Really happy to hear that, Eric! Thanks for sharing the photo too :) When do you get to take the boat out on the water again?

by:
Everything was exactly as ordered and delivered on time. The only thing that could be improved on is including the 4 bolts used to attach the caliper mounting plate. Most trailers requiring this type of repair are old and the bolts are rusted to the point of needing to be cut off. Thanks for the attention to detail on making sure the correct parts were ordered.
by:
Great upgrade over the original brakes, easy install and work great. Total time for installation was about 30 minutes each.
by:
fast delivery and very well packaged
by:
Easy installation, only issue I ran into was the OEM axle backing plate studs were to short. I searched everywhere for 3/8 drive in splined studs,, no luck, had to purchase grade 8 3/8x2 inch bolts!

Sorry to hear about the bolts, but glad you were able to find some that work Christopher =)

Brakes work great and after one year, still look great. The XL PROLUBE 2440 oil seal that come with is a poor choice. I had three of the for leak on a long trip. etrailer did the installation and was awesome to work with. They replaced all the seal with a better part at no cost.

I'm so glad we were able to turn this experience around for you and that these are still working great for you, James! How often do you tow?

I contacted etrailer to get their opinion on what components should be used to upgrade the brakes, hubs and wheels on my fifth wheel camper. They provide a list of parts for me to chose. I elected to use oil bath bearings and disc brakes. I purchase most of the parts from etrailer. The hubs and rotors were delivered in 4 boxes, unfortunately one of the boxes was destroyed and was returned. I contacted etrailer the next day and they immediately sent out the replacement parts. The installation was straight forward and took about 10 hours in my driveway. The one setback was that the mounting bolts for the drum backing plate were too short to mount the caliper brackets. The brake controller in the truck is a Prodigy 3 and works flawlessly with the electric over hydraulic brake actuator. The new disc brakes are a huge improvement over the drum brakes. If you are contemplating on whether to change your brakes from drum to disc. DO IT NOW! Thanks etrailer

Delivery was fast and on time As promised all the products and items that they said were coming with it showed up. The quality looks good and as advertised. I have not installed it yet once installed. I will review and give update.

I really like what I purchased.The system is really good and my trailer stops on a diamond gives 9 cents back, this is the way to go on any big trailer. Disks are amazing. No heat way better breaking, less maintenance. You know, the other thing? I did was upgraded My hubs to oil bath, which is another brilliant thing, again less maintenance. Better for the trailer, very impressed. The only negative thing I can say is that the seals for the oil bath are subpare and leaked after only 10 miles then 59 miles, so I had to go to a different manufacture and company and found a very robust seal that worked because the 2 times that yours failed that came from e trailer wasnt good. This is one problem. I think that they need to address and fix the other one. Is the caliper mounting bracket? When you put it on to the existing bolts on the spindle. The factory bolts are not long enough and I think that they should be changed. To a longer one so that you have according to engineering standards API three Threads showing when the nut is Torqued, you cant do it because the caliper mountain bracket is so thick and the bolts arent long enough. I Needed to change those bolts to longer bolt so that you can do this properly and have 3 threads showing past the nut When its torque down. Other than these 2 problems, everything seem to work very well and Im pleased.I have no other issues or concerns Prices were fair.Product came quick and Im real happy.So Far no other complaints for concerns.
