Disc Brakes

More and more people are switching their trailers over to disc brakes, and with good reason. Disc brakes deliver consistent braking - even at highway speeds - unlike drum brakes, which often show a substantial drop in braking torque at higher speeds. In addition, disc brakes offer a substantially shorter stopping distance than drum brakes. Disc brake calipers have only one moving part, rather than the many found in drum brakes. This means that there are fewer parts to maintain, fewer parts to get damaged, and fewer parts to have to repair or replace, thus reducing maintenance costs.


Corrosion Resistance for Marine Use

This disc brake assembly resists corrosion, making it ideal for use on your boat trailer. All KodaGuard calipers undergo a test in which they are sprayed with a 5-percent salt solution to determine corrosion resistance over time. These products are able to withstand 1,992 hours of constant exposure to the saltwater mist. This 1,992-hour salt spray rating indicates that this product is not only durable enough to last in freshwater environments, but it can also be used on trailers that come into contact with saltwater.


In addition, the rotors and caliper mounting brackets have a Dacromet plating, which offers a 300- to 400-hour salt spray rating. The pistons, the brake pad backings, and the caliper mounting bolts are stainless steel. These corrosion-resistant components make this Kodiak assembly a natural choice when installing disc brakes on your boat trailer.


Over-the-Hub Rotors for Easy Replacement

Kodiak's slip-on, cast iron rotor makes it easy to convert an idler axle to a disc brake axle. Simply place the rotor over your hub. It is most often wheel bolt piloted for a loose fit and then held in place by the wheel itself. With a separate rotor and hub, you can easily repair or replace one element of your brake system without having to junk the whole thing.


The rotor is made from cast iron, matching SAE specifications. Cast iron is ideal for high-temperature operations and offers a favorable friction coefficient to ensure adequate stopping power. Kodiak's rotors are vented to effectively dissipate heat, dramatically reducing the incidence of heat-related damage.


Calipers

Kodiak calipers are constructed of cast iron to prevent flexing. Less flex means more braking torque, resulting in smooth, even braking every time. The corrosion-resistant stainless steel piston is 30 percent larger than standard pistons, ensuring shorter stopping distance and increased torque. In addition, the unique low-drag design of Kodiak's calipers allows the piston to retract farther than in most standard models, giving you a cooler-running brake.


Mounting Brackets

Designed for axles with 4-bolt brake flange configurations, the included mounting brackets are made of heavy-duty ductile iron that is embossed to provide additional threading for guide bolts. The added thread strength ensures a tighter, more secure connection between the caliper and bracket. Another unique feature of Kodiak's brackets is the side-support angle, which guarantees that the load is carried by the bracket, rather than the bolts.

Video Transcript for Kodiak Disc Brake Kit Review

Speaker 1: Today we're going to be taking a look at the Kodiak line of Disc Brake Kits. Now, these kits are available in multiple configurations to fit multiple size axles. They're also available in several different finishes.A disc brake kit like this one from Kodiak is an excellent solution to give us good braking force. Typically, for this kit anyway, you're looking at like a 3500-pound axle. A lot of boat applications, you're hauling a boat sometimes miles and miles and miles, and without brakes on your trailer, you put a lot of unnecessary stress and strain on your truck. A braking kit like this allows us to take the stress, the strain off the braking system on our truck but also gives us a safer ride.In this application we've got a surge coupler at the front of the trailer, so as the truck slows it applies the hydraulic fluid pressure, squeezing our caliper together giving us excellent stopping abilities.

The rotors, calipers, and the ceramic pads are all automotive grade, so they're going to be made to the highest standards being sure we get excellent braking capabilities.Now when we compare a disc brake kit like this to a hydraulic drum-style brake, there are several advantages. Of course, we all know disc brakes tend to work better than drum brakes. They lock up less. We typically don't have the moisture being held inside. Especially in a marine application, that hub fills up with water, that moisture stays inside, causes some corrosion issues.

In this situation, once we bring these out of the water, everything's going to drain away. Air can get to it very readily and dry everything up.Another advantage we're going to get with this particular kit over the other disc brake kits available, the material composition is very corrosion-resistant. Our rotor, caliper, all stainless steel, plus they take that a step further, put a Dacramet finish all the way around. So that's going to work out really well, especially in a marine application like this, but also just on a utility trailer, keeping everything nice, corrosion-free. It's also going to be an excellent, excellent choice if you use it in a saltwater-type application.Something else you'll notice, pretty common on automobile applications, not usually on trailers, is going to be the ventilated rotor here.

So you've got two wear surfaces here and here. Those are going to be separated to allow air to flow freely in there and get everything cooled off to give us premium braking performance every time we hit those brakes.All right. With the bracket installed, we can move onto installing our rotor. That's one of the big benefits I like about this kit. You don't have the whole disc with the hub assembly in it.

So if you ever need to replace the disc, you're just replacing the disc, not your entire hub. This is going to fit right on our idler hub just like that, very common on automobile applications. They call this more like a top hat rotor where it it slides over your lugs, and then your wheel is actually going to hold that in and flush.Next, we'll move on to getting our caliper installed. Now the calipers can go either side. You don't have to have a left and a right. You can see we've got a bleeder screw on both sides. We want, of course, for our hydraulic connection to be facing in. Our slide bolts are going to come in this way just like that, and then these two portions are going to go on the back side of our bracket. So we slide that over, bring it in, and then we'll just push our bolts in, line them up with our holes and get them started. Now those do have loctite on them, so you'll just get them started a little bit, and then we'll use a 13mm socket and snug them on down.Now that we've got those snugged down, we'll use our torque wrench and we're going to torque them down to the specifications listed in the instructions. With our brake assemblies in place, it's time at this point to install our tire back on. Now, we do recommend using a torque wrench and torquing these down properly per the 1/2" stud application. Something we've seen, especially in the automobile industry, if you tighten these lug nuts down too much, you might cause that rotor to warp a little, decreasing your performance. That's going to complete our look at the Kodiak line of Disc Brake Kits.

Thanks!! What a great experience with etrailer.com. Trailer needed many parts, rusted, broken etc. Tried to contact maker of trailer for replacement parts, bad experience. Rude, unwilling to help, handling fees, VERY expensive shipping, and cash up front. I then turned to etrailer.com! Fantastic people on the line, sales personal were Kind, patient, and very knowledgeable about all my trailer needs. My parts arrived quickly, free shipping, and accurate. Not to mention I saved a bunch of money!!!! New Break System from front to back, new Trailer Winch. Thanks, Customer for life! 681685

This kit is about 90% complete. You only need to reuse your existing backing plate bolts or buy and install new. It takes about 20 to install on one axel. The instructions are pretty simple. I'm very satisfied with this kit. 664993

They went on fine. Only time will tell if the special blue coating helps with the saltwater exposure. Paired these with an elec over hyd actuator. Stops the boat trailer smooth. 656506

I'm sure the actual parts are great. Unfortunately I was sent the wrong hubs by mistake ( I received hub/rotors not rotors) . The calipers that were sent were also not Kodacoated . So..... no explanation of how the order got mixed up so badly from Etrailer although they were pretty good about getting the return set up through UPS. 431568

I have ordered trailer parts numerous times with etrailer. Once again, they came thru. Good prices and on my doorstep two days later. I'll be ordering again at etrailer when the need arises. I would also add that the sales person was extremely knowledgeable and helpful on the phone. 395047

After years of trouble with my trailer brakes, I overhauled my brake system using two of these kits and adding a set to the second axle. They are holding up well and have been used occasionally in salt water. I previously used kits that were hub and disk assemblies and I think separating them is a better alternative. I also installed greasable bolts on my springs and I'm really happy with those... Highly recommended! 250661

Ask the Experts about this Kodiak Trailer Brakes

Do you have a question about this Trailer Brake?


  • Replacement Recommendation For Disc Brakes For Three Axle Boat Trailer
  • The disc brakes you need will be determined by the weight of your axles (not the total capacity of your trailer), the size of your brake mounting flange (4-bolt most common), and the rotor diameter of your disc brakes. The best way to find the weight capacity of your axles is to look for a plate or sticker on your axles that provides information such as part number, lengths, and axle capacity (see attached picture). If the label is gone, then you can find the size with the diameter...

  • Can Trailer with Drum Brake Actuator Be Adapted to Work with Disc Brakes
  • Since you said "without a check valve" that makes me think you have a drum brake actuator that you are planning to remove the check valve off so that it might work with disc brakes instead. We're aware that this seems to work well for a number of people but when we have checked with the actuator manufacturers they won't safely endorse this. They'd require either swapping out the master cylinder of the actuator for one that is compatible with disc brakes or going with an all new actuator...

  • Recommended Disc Brake Kit For 20 Foot Boat Trailer
  • Brake lines can get clogged, and most of the time it has to do with someone not being careful when adding fluid and getting small particles inside instead of having disintegrated parts due to corrosion. To upgrade to disc brakes, you will basically need to replace everything except the brake lines which can be blown out with compressed air. The coupler will require a stronger master cylinder for disc brakes vs. drum brakes because disc brakes require 1600 psi where drums require 1000-1200...

  • How to Determine if Kodiak Disc Brake Kit K2R35DKG Will Fit a Trailer
  • As long as your axle has 5 on 4-1/2 inch bolt pattern idler hubs plus a brake mounting flange the Kodiak Disc Brake kit part # K2R35DKG will fit it. Look for a plate behind the spindle with 4 bolt holes in it for the flange. As long as the hubs of your trailer take L44649/L68149 bearings the bearing kit part # BK2-100 will fit them. As long as the trailer has a 3 inch wide frame channel the Demco part # 8608611 will fit. The tandem brake line kit part # 24TA-BLKIT will work with the...

  • Disc Brake Kits for Converting ShoreLandr Tandem Axle Boat Trailer to Disc Brake Operation
  • Installing disc brakes on your trailer that has drum brakes now will require new brake assemblies and also a new actuator that can provide the higher hydraulic pressure needed by disc brakes. You can stay with a straight hydraulic setup like you have now or you can install an electric-over-hydraulic (EOH) actuator that works with an electric trailer brake controller in the tow vehicle the way electric drum brakes do. I linked two articles for you, one covering each of those two disc...

  • Recommended Disc Brakes for a Magic Boat Trailer with 3,500 Pound Tandem Axles
  • Adding a disc brake system will be a great addition to your Magic boat trailer. The parts you will need are a brake mounting flange, spindle, disc brake assembly, hydraulic disc brake actuator and brake line kit. I recommend the Kodiak disc brake kit # K2R35DKG because it has rust resistant disc brakes and is great for boat trailers. The cast iron, slip on over the hub rotors are great because you won't need to replace your entire hub assembly. Note, as long as your bolt pattern is...

  • Axle and Hub Recommendation for Off Road Camper Trailer
  • When it comes to building an off road camper trailer, the best configuration that I can come up with is using the Timbren Heavy-Duty Axle-Less Trailer Suspension, # ASR35HDS02, with the Kodiak Disc Brake Kit, # K2HR526DKG. The heavy-duty steel construction and black powder coat finish of the axle-less system resists wear and corrosion and the rust-resistant, marine-grade, disc brake kit would be perfect for your set-up since you mention the fact of them going under water/mud on a regular basis.

  • Recommendation For Replacement Brakes For 1997 MacGregor 26X Sailboat Trailer
  • We will be glad to help but unfortunately there are all kinds of options and possibilities. The best way to find the right replacement brakes is to find the weight capacity of your axle (see attached picture), the size of your brake mounting flange (4-bolt pattern most common), and your drum diameter for drum brakes and rotor diameter for disc brakes. If your trailer has a 3,500-lb axle with drum brakes and a 4-bolt brake flange, I recommend something like the Hydraulic Brake Kit,...

  • Will Demco Disc Brake Actuator Put Out Enough Pressure for Kodiak Disc Brakes
  • The Kodiak Disc Brake Kit # K2R35DKG that you referenced does indeed require a psi rating of at least 1,500 for proper operation but this is standard for disc brakes. Any brake actuator that is designed for disc brake assemblies, such as the Demco # DM8605101, will absolutely provide the needed pressure. They don't typically have a specific psi rating but they will typically put out around 1,500 to 1,600 psi, varying a bit depending on the weight of your trailer, stopping force, etc. I...

  • To pick out the parts you need we would need more info from you. We don't have access to original equipment on your trailer and due to it's age it all could have been swapped out at this point. What you are looking for is basically a whole new disc brake kit. Which we most likely have but we first have to know what capacity axles you have so that we can pick out the correct kit.
