    Perfect for Boat Trailers

    Kodiak disc brakes installed on a trailer

    If you tow a boat trailer, live in a coastal area, or experience a lot of snow, slush, and salt on the roads, you know how corrosive salt and water can be. Because disc brakes last longer than drum brakes, you should consider how things like rust might impact your trailer over time.

    The Dacromet coating on these brakes offers great corrosion protection, even with frequent use in freshwater and saltwater. It can withstand 300 to 400 hours of continual exposure to salt spray before corrosion begins, which is comparable to galvanized steel. And the KodaGuard coating on the calipers offers even better corrosion resistance, as it can withstand 500 to 600 hours of salt spray before rust forms. So - unless you're driving your trailer through water for 2 weeks straight with no chance for the brakes to dry - it'll be a while before any rust starts to form.

    Get a Safer, More Comfortable Ride

    Say goodbye to the days of your truck being pushed and pulled by your trailer. Disc brakes provide a safer, more comfortable ride than drum brakes. They offer shorter stopping distances and deliver consistent braking - even at highway speeds. So, you won't have to worry about things crashing around in your trailer or camper next time you reach unexpected traffic on the highway or debate if you can actually stop before that yellow light turns red.

    Save Time and Money

    More and more people are switching their trailers over to disc brakes. Not only do disc brakes provide more controlled braking than drum brakes, but they also save you money by having fewer parts to maintain.

    Unlike drum brakes, which have springs, magnets, and shoes that may need to be continually adjusted or replaced, disc brakes are virtually maintenance-free. There are no springs, cables, or other little components that you'll need to worry about failing.

    The brake pads will naturally wear down, so eventually you'll have to replace them. But these pads are also way easier to replace than drum brake shoes. The caliper - where the pads are housed - is located on the outside of the brake assembly. This means you just have to remove that one part to replace the brake pads rather than having to remove the entire assembly like you would with drum brakes.

    This particular kit can save you time and money over other disc brakes on the market as well. A slip-on rotor may be easier to install initially, but water can find its way between the rotor and your existing hub, causing uneven rotor wear or runout. With a 1-piece hub-and-rotor assembly, water and debris can't get in to cause any corrosion or contamination.

    In addition, vented rotors, like these, disperse heat faster than non-vented rotors. When brakes retain heat, they are more likely to experience brake fade, or loss of braking power. So even if you take your boat or camper out every weekend, these trailer brakes will continue to offer excellent performance throughout their long life.

    mounting bracket supporting disc brake

    Kodiak disc brakes have a unique caliper mounting bracket as well. The side-support design puts all of the weight on the mounting bracket instead of on the bolts. This reduces premature wear and extends the life of the bolts, further ensuring optimal performance.

    Determining the Bolt Pattern

    If you want to remount your existing wheels after installing these brakes, you'll need a kit that offers the same bolt pattern. To determine the bolt pattern, count the number of bolt holes (or lug nuts) on your trailer's wheel. This will give you the first number in the pattern. To find the second number, just measure the distance between a bolt hole and the bolt hole across from it.

    diagram showing how to measure even bolt pattern

    For example on wheels with an even number of bolt holes: 6 on 5-1/2" means 6 bolt holes with 5-1/2" from the center of 1 hole to the center of the hole across from it.

    diagram showing how to measure odd bolt pattern

    And with an odd number of bolt holes: 5 on 4-1/2" means 5 bolt holes with 4-1/2" from the center of 1 hole to the farthest edge of one of the 2 farthest bolt holes.

Video Transcript for Review of Kodiak Trailer Brakes - 12" Hub/Rotor - 6 on 5-1/2 - Dacromet Disc Brakes - KOD89FR

Hi there. I'm Michael with Today, we're gonna take a quick look at this Kodiak 12 inch hub and rotor disc brake assembly set. Now, this is going to allow you to upgrade your trailer from drum brakes to disc brakes so that you can take advantage of all the added benefits of having disc brakes on your trailer. We are gonna have the two brake assemblies here. So, that's going to allow you to replace the brakes on a single axle with a capacity range from 5,200 pounds to 6,000 pounds and the number 42 spindles on that axle.

As you can see, these are going to be a 12 inch diameter on our rotor. And then we're gonna have the six on 5 1/2 inch bolt pattern so these are going to work with your wheels that are 15 inches and larger. So, upgrading your trailer from drum brakes to disc brakes, it is gonna have several different benefits. It's going to help shorten your stopping distance. It's also going to help provide smoother, more controlled braking than you're used to experiencing with your drum brakes so it's gonna help keep your trailer from pushing and pulling as you're going down the road.

Now, these do have the ceramic brake pads that are going to help increase your stopping power. And it's kind of hard to see but there is a large 2 1/4 inch diameter stainless steel piston that's gonna provide fast, responsive braking for you. In addition to the added performance, these are also going to require less maintenance, and therefore save you time and money over your drum brake. So, there's not as many little components that could fail and have to be replaced over time. Those brake pads will wear down over time and have to be replaced, but that's a pretty simple process and it's not gonna happen very frequently.

So, this is gonna be a great money saving option for you as well because we have the one-piece hub and rotor assembly. That's gonna help reduce the chance of uneven rotor wear. We do also have the vented design that's gonna help dissipate your heat faster to prevent premature brake pad wear. And these are a high-quality, automotive-grade construction so they are gonna be very long-lasting. We also have the Dacromet finish on our hub and rotors and on the brackets on the backside here.

So, those are all gonna be coated to help offer rust and corrosion resistance. And they have a 300 to 400 hour salt spray rating so they're gonna hold up really well. And then on our calipers, we have a KodaGuard coating that's going to offer 500 to 600 salt hour spray rating. So, these are gonna be a great option for your boat trailers and trailers that are used in coastal areas or on heavily treated roads. We're gonna have have a lot of contact with salt. These are gonna hold up really well for you. So, one caveat with disc brakes, they are going to require a higher line pressure than your standard drum brakes. And so, you're gonna need a hydraulic brake actuator and brake lines that are rated for 1500 psi or above in order to operate your disc brakes here. So, if you don't already have those, we do sell them separately here at So, this kit isn't going to include everything that you need if you don't already have the brake lines and hydraulic brake actuator rated for that 1,500 psi and pressure. But these are going to include the two Dacromet plated cast iron hub and rotor assemblies with the six preinstalled half-inch wheel bolts as well as the 12 zinc plated steel lug nuts that you're gonna need to hold your wheels in place there. You're also going to get the two KodaGuard coated cast iron calipers and two Dacromet plated, ductile iron caliper mounting brackets. And so, these do have the five-bolt brake flange configurations so it's gonna be very easy to get these mounted on your axle. One thing I do wanna note, I have these mounted on the top just for display purposes, for balance and whatnot. When you're installing these, they're actually gonna be on the side and that's gonna be an added benefit for you because that's going to put the weight on the mounting bracket instead of on the bolts. So, those bolts are gonna have less strain and it'll hold up longer for you. You're also gonna get four of these stainless steel caliper mounting bolts to get everything put together there. Make sure that those are held in place properly. In addition to the main assembly there, we're also going to get our inner and outer bearings. Those are going to obviously make sure that our system can rotate on our axle properly. So, you can see the part numbers on the screen there. And then we're also gonna have our inner and outer races that the bearings are going to fit into. Those are preinstalled but you can see those part numbers on the screen there as well. And then we're also going to have our inner grease seal. It's gonna be on the inside portion there to hold the grease in that grease seal. It's gonna have a 2.25 inch inner diameter and a 3.376 outer diameter. And then we'll also have our grease cap. This is a E-Z Lube grease cap so we can pop out that rubber plug there, have easy access to our spindles so we can pump in some grease, make sure everything's well lubricated in between our normal changes. And that outer diameter is 2.45 inches. So overall, a very nice system here to upgrade your trailer from those drum brakes to disc brakes. That Dacromet finish is gonna hold up really well against the salt. If you're looking at your good, better, best, I would say your Dacromet finish is probably your better category. Stainless steel would be your best. It's gonna hold up the longest for you. But these are going to be a little bit more cost effective and they're still gonna do a really good job for you as well. So, that completes our look for today. Again, I'm Michael with Thanks for watching..
