If you’re replacing worn drum brakes or upgrading your setup, this 13" Kodiak disc brake kit gives you a major boost in stopping power. Each 1-piece hub-and-rotor assembly bolts right on to a #42 spindle for a 7,000-lb axle with an 8 on 6-1/2" bolt pattern and 1/2" wheel bolts. The large, stainless steel piston and ceramic pads create fast, consistent braking that feels smooth and controlled even at highway speeds.
Saltwater, slush, and coastal air can take out bare metal brakes fast. These Dacromet-plated hub-and-rotor assemblies, calipers, and brackets hold up to 300 to 400 hours of salt spray before corrosion starts. That makes them ideal for trailers that see wet or treated roads all season long. The coating protects every major component for long-term reliability in rough conditions.

Heavy towing generates serious heat, but these vented rotors spread it out fast. The vented design dissipates heat quicker than solid rotors, cutting down on brake fade and extending pad life. You get repeatable, confident braking even when hauling over long grades or stopping under load.

This complete kit comes ready to mount with everything needed for one axle—inner and outer bearings (25580 and 14125A), races (25520 and 14276), grease seals (10-36), E-Z Lube caps, wheel bolts, and lug nuts. The disc setup has no springs or magnets to replace and requires minimal maintenance over time. When the pads wear down, they’re easy to access right from the outside of the caliper for a quick swap.

Every part of this system is built for strength. The cast iron hub-and-rotor assemblies are paired with ductile iron caliper brackets that use a side-support design to carry the load on the bracket instead of the bolts. That detail prevents bolt wear and keeps your braking system solid over time. With automotive-grade materials, stainless steel hardware, and a 3-year warranty, it’s made for lasting performance through repeated towing seasons.

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 that comes along with having disc brakes on your trailer. Having the two brake assemblies is going to allow us to upgrade a single axle with a 7,000 pound capacity and the number 42 spindles. Our rotors are 13 inches in diameter and you can see we've got eight of these half inch diameter bolts in the 8 on 6 and a half inch bolt pattern. So these are going to work for your wheels that are 16 inches and larger.
Our hub and rotor as well as our calipers and our mounting bracket, all have this Dacromet finish that's going to offer excellent rust and corrosion resistance with 300 to 400 hour of salt spray rating. So this is gonna be great option for your boat trailers and trailers that are used in coastal areas or on roads that are gonna be heavily treated. So if you're looking at your good, better, best kind of scenario, I'd say your Dacromet is probably your better. There is stainless steel construction that is going to be a little bit better, little bit longer lasting but your Dacromet is definitely one of your best options out there as far as corrosion resistance goes. So this is gonna do a great job for you on that side.
It's also going to give you a much better performance than you're used to with your drum brakes. Having the disc brakes is going to dramatically shorten your stopping distance. It's also going to make it a much smoother, more controlled ride for you so you don't have to worry about that push and pull that you sometimes get with your drum brakes. These do have these ceramic brake pads that help to increase the stopping power and you can't see it, but there is a large 2 and a half inch diameter stainless steel piston that's gonna provide fast, responsive braking for you. So definitely an improvement over your drum brakes.
And not only are you going to get better performance but it's also going to require less maintenance and therefore it's gonna save you time and money. Having the one piece hub and rotor assembly is gonna reduce the chance of uneven rotor wear. And then here on the side, we do have the vented design that's gonna help dissipate heat faster to prevent premature brake pad wear. So overall, a really great quality, automotive grade construction that's going to be very long lasting to help save you time and money. Doesn't have all the small springs and different things that your drum brakes do, and so less to have to replace in the future.
The one caveat with disc brakes is that they do require a higher line pressure and so you're 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. That's pretty rare on trailers that have drum brakes currently so that is gonna be a bit of a project to upgrade the rest of your system. But we do sell both the actuator and the brake lines here at etrailer.com and those are sold separately. They're not included in this kit. So this kit isn't gonna give you everything that you need but it is going to include the two Dacromet plated, cast iron hub and rotor assemblies with those eight pre-installed wheel bolts that have that half inch diameter. You're also gonna get the 16 of these half inch zinc plated steel lug nuts to make sure that your wheel stays in place. You're gonna have the two Dacromet plated, cast iron calipers and the two Dacromet plated, ductile iron caliper mounting brackets. And these brackets you can see, have the 5-bolt brake flange configuration. So they are gonna be very easy to put in place on your axle. Now I do want to point out that I do have these mounted on top just for display purposes, for balance and whatnot. When you actually install these, they're gonna be on the side and having that side support design puts all the weight on the mounting bracket instead of the bolts here. So it's gonna help to take some of the pressure off those bolts, make sure that they last longer. These are stainless steel caliper mounting bolts. You're gonna get four of these with this kit. You're also going to have the inner and outer races pre-installed on the system so those are included obviously but then you'll also get your inner and outer bearings to make sure that everything's running smoothly. This kit is going to be lubricated with grease so you're going to get two of these grease seals for the inside. And then two of these E-Z lube grease caps for the outside. Those do have that removable rubber plug so that you can very easily access your E-Z lube spindles, pump some grease in there without having to take everything apart in between your regular grease bearing, packing maintenance. So overall, like I said, a great upgrade coming from drum brakes to disc brakes, gonna give you much better performance, require much less maintenance and having that Dacromet finish on there is going to make sure that these last a nice long time for you. 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?
