If your old drums are dragging or fading, this Kodiak 13" disc brake kit is a serious upgrade. The 1-piece hub-and-rotor assemblies use ceramic brake pads and large, stainless steel pistons for fast, responsive braking and dramatically shorter stopping distances. With their vented rotors and automotive-grade construction, these brakes give you smooth, confident control every time you stop.
Rust is a real problem when you tow in coastal or winter conditions. The Dacromet coating on these cast iron hubs, calipers, and brackets provides excellent corrosion protection with a 300- to 400-hour salt spray rating. Even with frequent freshwater or saltwater use, the protective finish holds up far longer than standard coatings, helping your brakes stay safe and reliable season after season.
This setup cuts down on maintenance and saves time compared with typical drum or slip-on systems. The integrated hub-and-rotor design keeps water and debris out to prevent uneven wear or corrosion between surfaces. Fewer moving parts mean fewer chances for failure—no springs, magnets, or cables to replace—just simple pad swaps when needed.
Towing heavy loads or climbing long grades can heat brakes fast. These vented rotors disperse heat quickly to reduce brake fade and extend pad life. That means consistent stopping power even when your trailer is loaded down or you’re driving through tough terrain.
The kit includes two Dacromet-plated hub-and-rotor assemblies with inner (25580) and outer (02475) bearings pre-installed, matching races, grease seals, E-Z Lube caps, (16) 5/8" wheel bolts, and (16) 5/8" zinc-plated steel lug nuts. It’s rated for 8,000-lb Dexter #42 spindles with an 8 on 6-1/2" bolt pattern and fits wheels 16" and larger. A hydraulic actuator rated at 1,500 psi or higher and brake lines (sold separately) are required to complete the setup.

Hi there, I'm Michael with etrailer.com. Today we're gonna take a quick look at this Kodiak 13 inch 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 of disc brakes. This kit is going to include these two brake assemblies so you can upgrade a single Dexter axle with an 8,000 pound capacity and the number 42 spindles. Our rotors are 13 inches in diameter, and as you can see we've got the 8 on 6 1/2 inch bolt pattern. So these are going to work for your wheels that are 16 inches and larger.
Our hubs and rotors, as well as our calipers and our caliper mounting brackets all have a Dacromet finish that's gonna offer excellent rust and corrosion resistance, with a 300 to 400 hour salt spray rating. So these are going to be great for your boat trailers and trailers that are used in coastal areas or on heavily treated roads where you're gonna have a lot of contact with salt and that sort of thing. So if you're thinking about good, better, and best, your Dacromet is probably in your better category. The only one that I know of that's better quality would be stainless steel construction. But if you're looking at finishes, a Dacromet is gonna do a really good job, hold up well for you for a long time to come.
And upgrading your trailer from drum brakes to disc brakes is going to have several different advantages for you. One, it's going to dramatically shorten your stopping distance so it'll be a much more effective for you. And it's also going to be much smoother, more controlled ride, so you're not gonna have to worry about that pushing and pulling that you're probably used to with your drum brakes. These do use these ceramic brake pads that will help increase the stopping power. There's also a large 2 1/2 inch diameter stainless steel piston here that provides fast, responsive braking for you.
So it is gonna be an improved performance over your drum brakes and you're also going to have less maintenance than your drum brakes. So it's gonna help save you time and money over the long run. Having the one-piece hub and rotor assembly is gonna reduce the chance of uneven rotor wear. We also have the vented design here that's going to help dissipate heat faster to help prevent premature brake pad wear. So overall, will hold up really well.
These are a high quality automotive grade construction so they are gonna be very long lasting for you. So again, save you time and money down the road. The one caveat with disc brakes is that they do require a higher line pressure. So you are gonna need to make sure that you've got a brake actuator and brake lines that are rated for 1500 psi or higher in order to activate your disc brakes here. So if you don't already have those, we do have them available here at etrailer.com. But they are sold separately, they're not a part of this kit but this kit will include these two cast iron hub and rotor assemblies with the eight pre-installed 5/8 inch diameter wheel bolts each. And then you're also going to get 16 of these 5/8 inch zinc-plated steel lug nuts that will allow you to ensure that your wheel is connected. We'll get the two cast iron calipers as well as the two caliper mounting brackets. These are ductile design and you can see we've got the four-bolt brake flange configuration here, so it is gonna be very easy to get installed on your axle. I do want point out that I do have these mounted on top right now just for balance and display, but when you go to install them, they'll actually be on the side. And so having that side support design is gonna put all the weight on your mounting bracket itself instead of on the bolts, so your bolts are gonna last longer. You are going to get four of these stainless steel caliper mounting bolts as well. And then our inner and outer races are pre-installed. We've got our inner and outer bearings that are included, keep everything rolling smoothly. This system is a grease lubricated setup so you're going to get your grease seals for the inside and then your EZ-Lube grease caps for the outside here to make sure that grease stays in where it needs to be. So like I said, this is gonna be a a great upgrade for you. With that Dacromet finish, it's gonna hold up really well and you're gonna get the benefits of the the disk brake's better performance. So that completes our look for today. Again, I'm Michael with etrailer.com. Thanks for watching.

Nothing new which is good news, although I will replace the bearings sometime this winter with Timken. This is the stock brake for Morryde IIS and it work well enough. The China bearing are what it comes with, but in an effort to not have to worrywonder, Timken is my choice. Not sure about some of the complaints but other than cardboard not holding up to heavy metal mine were new and good. I believe sometimes returns and part get put in a box a second time and that screws everyone up. Not being an upgrade, I am not sure there is another choice even if I wanted it.

I decided to go with the Kodiak set up and we couldn’t be happier with the service with them. I feel that the trailer stops around 40 better.
Do you have a question about this Trailer Brake?
