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 - KOD29FR

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. So this is going to allow you to upgrade your trailer from drum brakes to disc brakes so you can take advantage of all the benefits of disc brakes. The two brake assemblies here are going to allow you to replace the brakes on a single axle with a capacity range of between 5,200 pounds and 6,000 pounds. That has the number 42 spindles on it. Our rotor is 12 inches in diameter and you can see we've got the six on five and a half inch bolt pattern.

So these are going to work with your wheels that are 15 inches and larger. So upgrading from drum breaks to disc brakes is going to have several benefits. It is going to help dramatically shorten your stopping distance. It's also going to provide smoother, more controlled braking. So it's gonna keep your trailer from pushing and pulling as you're probably used to experiencing with your drum brakes.

These do have ceramic brake pads that are going to help increase your stopping power and it's kind of hard to see, but up here at the top, we are gonna have a large two and a quarter inch diameter stainless steel piston that's gonna provide fast, responsive breaking for you. So in addition to better performance, these are also going to require less maintenance. There's fewer parts that could fail for you than with your drum breaks. Gonna be less to have to maintain to tighten frequently and that sort of thing. So these are pretty maintenance free so 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. We 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. Our hub and rotor have the Dacromet finish on them as well as the mounting bracket on the backside here. So that's going to offer excellent rust and erosion resistance.

And these do have a 300 to 400 hour salt spray rating with that coating on them. And then our calipers are gonna have the coat guard coating and that's gonna provide 500 to 600 hours of salt spray rating. So these are gonna be a great option for your boat trailers or trailers that are used in coastal areas or in heavily treated roads where there's gonna be a lot of contact with salt. These will hold up really well for you. So the one caveat with disc brakes is that they are gonna require a higher line pressure than your standard standard drum breaks. So you're gonna need a hydraulic brake actuator and brake lines that are rated at 1500 PSI or higher in order to activate your brakes. So if you don't already have those, we do sell those separately here at So this kit isn't going to include everything that you need if you don't already have brake lines and an actuator that are rated at 1500 PSI. But it is going to include the two Dacromet plated cast iron hub and rotor assemblies with the six pre-installed half inch wheel bolts on each one as well as the 12 half inch zinc plated steel lug nuts that you're gonna need to make sure that your wheel stays in place. We're also gonna get the two coat guard coated cast iron calipers as well as the two Dacromet plated ductile iron caliper mounting brackets. So you can see these do have the five bolt brake flange configuration so it's gonna be very easy to get mounted onto your axle. I do wanna note that I do have these on top for demonstration purposes but when you actually go to install them, they're gonna be on the side so that's going to put the weight on the mounting bracket instead of on the bolt so it's gonna help your hardware hold up longer and last you a nice long time. I just have these up here to help me balance them a little bit better than they could on the side but when you actually install them, they'll be on the side there. In addition to the calipers and the brackets, we are gonna get the stainless steel mounting bolts on the backside here that are going to attach those two. And we're also going to get our inner and outer bearings. Those are going to obviously make sure that everything's rotating properly around our axle and will fit into the races that are inside pre-installed. We've got our inner and outer races. You can see all those part numbers on the screen there so if you have any questions you can look those up but very simple process there. And then we're also going to have our oil kits. So we've got our oil seals that are gonna be on the inside. These have a 2.25 inch inner diameter and a 3.376 outer diameter. Our cap is going to have a 2.44 inch outer diameter. And then we're also going to get one eight ounce bottle of synthetic bearing oil to make sure that everything is operating nice and smoothly. So this is gonna be a great kit for upgrading if your axle. Currently has the drum brakes installed on it. This is going to give you better performance, require less maintenance, and it's gonna hold up really well with that Dacromet finish on there. So that completes our look for today. Again, I'm Michael with Thanks for watching..


See what our Experts say about this Kodiak Trailer Brakes

  • What is the Blue Coating on the 5.2K to 6K Kodiak Disc Brakes
    The blue coating on the Kodiak Disc Brakes # KOD29FR is the KodaGuard coating on the calipers. The normal Dacromet coating on the brakes which has a 300- to 400-hour salt spray rating while the KodaGuard has an upgraded 500- to 600-hour salt spray rating so it's more durable. Even though these do well to hold up to salt water it's still a good idea to hose down your boat trailer with fresh water once you're done boating to help prolong the life of your trailer.
