Kodiak Rotor Diagram

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.


Over-the-Hub Rotor

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.


Calipers

Kodiak calipers are constructed of stainless steel to prevent flexing and rust. 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, corrosion-resistant dacromate-plated steel 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.

Do you have a question about this Trailer Brake?


  • Replacement Disc Brake Kit and Hubs for Dexter 3,500 lb Axles
  • If the rotors are in excellent condition, are the slip on style that slip over the mounting studs it could work. But you will need to make sure they are the exact same dimensions as the ones designed to work with the kit you are interested in. But honestly, anytime you change brake pads you are supposed to either replace the rotors or have them machined. And at the price of just getting new ones in Dacromet or Silver Cadmium (which are both reasonably priced and offer good corrosion...

  • What Additional Hardware is Required to Install a Kodiak Disc Brake Kit # K2R35DS
  • I spoke with my contact at Kodiak about the Kodiak Disc Brake Kit, part # K2R35DS, and found out what is included and what you would need to supply. Basically, all you will need to supply is the bolts that the bracket to the axle. Other than that everything else should be included. I attached installation instructions for this product below for you to check out also.

  • Best Disc Trailer Brake Kit for Salt Water Use on 3500 Pound Axle
  • The Kodiak disc brake kit # K2R35DS is made up of Dacromet and stainless steel components. Dacromet has a 400 to 600 hour salt spray rating while stainless steel is about as corrosion resistant as you can get. Still when using these items in a salt water environment be sure to hose them off after use with fresh water. For the absolute best in corrosion resistance go with an all stainless kit like # K2R35S. I have linked installation details for you. I have also included a link to our...

  • 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...

  • Disc Brakes Recommendation For 3500 Lb Boat Trailer
  • The Kodiak disc brake kit you asked about, part # K2R35DS, will fit 3500 pound axles with wheel sizes 14 inches or larger. The 10 inch rotors have a 5 on 4-1/2 bolt pattern. The additional 1/2 inch would mean the wheels would indeed be mounted approximately 1/4 inch further out on each axle. The existing hubs along with the bearings and races would have to be removed. You mentioned that the axle has a 4 bolt flange already welded to it. I have attached a photo of how the brake mounting...

  • Diameter of Kodiak Rotor Flange
  • The inside flange diameter of the rotor from the Kodiak Disc Brake Kit # K2R35DS measures 3-11/16" and the outside diameter of the Dexter Trailer Idler Hub # 84655UC1 measures 2", though please be aware that you should not drill a new wheel bolt pattern on the rotor; doing so would compromise the integrity of the rotor and would not be safe. What you need to do instead is either use a 12" rotor with a 6 on 5-1/2" bolt pattern such as # K2R526S or get a new idler hub assembly with a 5...

  • What Kodiak Brake Hardware is Compatible with Tie-Down Brakes on a Load Rite Trailer
  • I have contacted the two manufacturers but I have been unable to confirm the compatibility of the rotors from one company with the calipers from the other. Depending on how tightly and for how long the original calipers have been frozen in their current position, it may be that your rotors have been damaged by scoring or corrosion. We always recommend that all braking system parts be replaced at the same time using rotors and calipers from the same manufacturer, which ensures both compatibility...

  • Replacement Rotors and Calipers for Oil Bath Hub
  • As long as your hubs are in good condition, a slip-over kit like the Kodiak Disc Brake Kit # K2R35DS that you referenced will work well and be easiest to replace the rotors and calipers. You will want to ensure that the kit matches your hubs. The # K2R35DS kit has a 10 inch rotor with 5 on 4-1/2 inch wheel bolt pattern and is designed for 3,500 pound axles.

  • Can an Older Car Trailer Have New Kodiak Disc Brakes Installed
  • As long as there is a brake mounting flange on the spindle of your trailer axle there should be a way to get new disc brakes on the trailer. Basically you would need to first determine what spindle you have on your trailer so that we can figure out what hub/rotors are going to fit. If you check out the help article I attached you will see a guide that will walk you through the entire process. The part # K2R35DS that you referenced is a slip on kit that will fit over idler hubs on...

  • Rotor Size of Kodiak Disc Brake Kit for 3,500 lb Axles
  • The size of your current rotors are not indicative of the rotors you can replace them with. The Kodiak Disc Brake Kit # K2R35DS has 10" rotors but in order for the kit to work you only need to ensure you have a 4-bolt brake mounting flange, #84 spindles, as well as wheels that have a 5 on 4-1/2" bolt pattern and are at least 14" in diameter.

  • Will the Additional Width from Slip-Over Rotors Affect the Fit of the Brake Calipers on a Trailer
  • There is some additional width added when using the slip-over rotors like # K2R35DS. This is true on every application that uses this set up. The brackets and calipers are designed for this so they will line up just fine. The wheels and tires will just be 1/2 inch further out on each side. You will need to make sure that your existing axles have brake mounting flanges in order to add brakes to the trailer. If you do not have a 4-bolt mounting flange on each end of the axle, # 4-35, you...
