If your old brakes are dragging or losing bite, these 13" Kodiak disc brakes deliver a serious upgrade. The one-piece hub-and-rotor assemblies provide smooth, controlled stops with dramatically shorter braking distances. Ceramic pads and a large 2-1/2" stainless steel piston create fast, responsive braking, while the 7,200-lb axle capacity gives you plenty of stopping power when loaded heavy.
This complete kit comes with everything you need for one axle—hub-rotor assemblies, calipers, brackets, bearings, races, oil seals, oil caps, synthetic bearing oil, wheel bolts, and lug nuts. The integrated design means fewer parts to maintain and eliminates the tedious setup of drum brakes. Once installed, there are no springs or cables to adjust—just reliable braking that stays consistent over time.


Rain and road grime can eat away at metal over time. The E-coat finish on these cast iron hub-and-rotor assemblies and calipers provides rust and corrosion resistance with a 250- to 350-hour salt spray rating. It’s tough enough for regular use in wet or humid conditions while keeping the braking surfaces clean and effective.
Long downhill grades or heavy towing can create heat that leads to fade. These vented rotors dissipate heat faster than solid rotors, keeping braking smooth and consistent even under sustained pressure. That extra cooling also helps extend pad life so your brakes stay strong season after season.

With an 8 on 6-1/2" bolt pattern and 5/8" wheel bolts, this setup fits standard #42 spindles and wheel sizes 16" and larger. The side-support caliper mounting bracket design puts the load on the bracket instead of the bolts to reduce wear and extend hardware life. Every piece is automotive-grade quality backed by a 3-year warranty for dependable service down the road.

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 here is going to allow you to upgrade a single 7,200-pound capacity axle with the number 72 spindles. Our rotors are 13-inches in diameter, and we've got the eight on 6 1/2-inch bolt pattern with these 5/8-inch diameter wheel bolts. So these are going to work with your wheels that are 16-inches and larger.
Our hub and rotor assemblies as well as our calipers here are E-coated. So they are gonna help resist rust and corrosion with a 250 to 350 hour salt spray rating. And that's gonna provide adequate rust protection for your camper, car hauler, or utility trailer. If you're gonna be using disc brakes for a boat trailer or a trailer that's gonna be coming into contact with heavily treated roads, a lot of salt and that sort of thing, I would recommend going more with a stainless steel construction. Those are gonna hold up better in those kind of really salty environments but if your trailer isn't gonna be in those kind of environments, these are gonna do just fine for you.
Upgrading your trailer from drum breaks to disc brakes is going to give you much better performance. You're gonna notice an improvement. They are going to help shorten your stopping distance. These do use ceramic brake pads here that are going to help increase the stopping power. And then there is a large 2 1/2-inch diameter stainless steel piston that provides fast responsive braking.
So overall it's gonna give you a smoother, more controlled braking experience. So it's gonna help keep your trailer from pushing and pulling like you're probably used to with your drum brakes. And in addition to better performance, these are also going to require less maintenance than your drum brakes. So it's gonna help save you time and money over the long run. Having that one-piece hub and rotor assembly reduces the chance of uneven rotor wear.
And we have the vented design here on the side. It's gonna help dissipate heat to prevent premature brake pad wear, so these are gonna do a great job, hold up really well for you. They don't have the springs like your drum breaks so it's going to be less components that could fail for you and have to be replaced. Your brake pads will wear down eventually you'll have to replace those, but it's a pretty straightforward process. And overall this is a high quality automotive-grade construction, so it is gonna be very long-lasting. Will help save you that time and money to switching out all those components and replacing them, that sort of thing. So one caveat to upgrading from drum breaks to disc brakes is that your disc brakes do require a higher line pressure. So you need a brake actuator, a hydraulic brake actuator, and brake lines that are rated for 1500 PSI or higher, in order to activate these. That's gonna be pretty rare for your trailers that are set up for drum brakes. So it might be a project to get everything switched over. If you don't already have a hydraulic brake actuator and brake lines, we do have those available here at etrailer.com. They are sold separately. They're not included in this kit, so this isn't gonna give you everything that you need. But this is going to give you the two E-coated, cast iron hub and rotor assemblies with the eight pre-installed, the 5/8-inch diameter wheel bolts on each. You're also going to get 16 of these 5/8-inch zinc-plated steel lug nuts to hold your wheel in place. We'll get the two E-coated cast iron calibers as well as the two Dacromet-plated, ductile iron caliper mounting brackets. You can see these do have the four-bolt brake flange configuration, so they are going to be very easy to get mounted on your axle. One thing I do wanna point out I've got these mounted on top just for display purposes for balance and that sort of thing, but if you, when you go to install them, they are 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 going to get four of the stainless steel caliper mounting bolts with this kit and our inner and outer races are pre-installed or in addition to our races. We're also going to get our inner and outer bearings that will fit inside there, will rotate around, keep everything moving nice and smooth. This kit is lubricated with oil so you're gonna get your two oil seals and two oil caps to make sure that your oil stays in place. You're also going to get one eight ounce bottle of synthetic bearing oil to put in there and make sure that everything is well lubricated and moving smoothly. So like I said, if you are wanting to upgrade your trailer from drum breaks to disc brakes or if you already have disc brakes, you're just wanting to upgrade your brakes to a higher quality finish these are gonna be a great option for you and they're gonna do a really good job. That completes our look for today. Again, I'm Michael with etrailer.com. Thanks for watching.
