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.

Integral Hub-and-Rotor Assemblies

The integral hub-and-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. Furthermore, machined disc brakes minimize the chance of contamination between the hub and rotor, resulting in excellent performance and long life.


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 Trailer Disc Brake Kit Installation

Ten is a boat trailer were going to do a Kodiak disc brake install part number K2HR35D. Before you kept put this conversion kit on, double check to make sure the coupler at the front of your trailer is ready for disc brake use. Sometimes surge brake couplers arent designed for disc brakes. Now were going to start off with our trailer actual strip down it previously had drum brakes on it so we take off the hub and we take off the drum brake. We also pull the brake line out of the way. Were going to point up all the way so that it wont drain all the fluid.

Now were going to move on to our Kodiak kit. We have the parts laid out for one side of axle. We add the drum, brake pads, and a caliper. This is a bracket that will attach everything to the axle and necessary hardware. Were also going to add to the kit which is not included as a flexible line kit thats going to be part number 80910 from red line.

You need two of these kits to do a complete install. Lets start off from our bracket well install it first, two things to make sure of is that this triangle piece here points towards the inside of the trailer and our caliper will be end up point towards the back of the trailer. So go ahead and use the provided hardware to install it. And go ahead and tighten everything down. Now again, install our hub and disc all in one piece and just install just like any other hub.

And we go ahead and reinstall the green cap. All right, now were going to work with caliper we take the one pad and secure it tight that youre going to get just right and it pops into place. And our second pad theyll spring goes into the cylinder and were good to go. We can go ahead and bolt this on to our bracket. We use this bolt right here to run to your caliper and into the bracket.

Would be one on top and would be one at the bottom, all right And snug goes down evenly on both sides and then tighten them down for good. Were going to go ahead and install flexible brake line in this caliper and then we run it at to this 16 line here. You can see how a brake line is pretty long as application would take the original line and coil it up to take it up to the slack. Now when we get done coiling it up, we want to route it were always go down like so coil down still like this. Then we can go ahead and install the bracket for brake line we use the same attachment point here and run everything together. Looks like clipping the place. Its tap down in place then were going to align it to it. Now were done to pass your side, this will go to your driver side repeats the same process. Double lines with gap you go ahead and bleed the brakes. When we bleed the brakes well start with the brakes as far as away from the surge coupler. We go ahead and up on a bleeder is here, the one on the top, it will take feet of rubber line pushing over to the top and the other half into a jar. And then well pump surge coupler until we see bubbles clearing out the lines. Once the brakes are all in bled, were good to go. Lets put the tires and wheels on here and were ready to roll.

Based on your bearing numbers and spindle measurements you need a 3,500 lb hub with a 5 on 4-1/2 bolt pattern. The type of hub that you need will depend on whether you have brakes or want a galvanized versus a painted finish. For idler hubs (no brakes), you can use part # 84545BX or # 84545UC1-EZ for EZ Lube spindles. These hubs are also...

For a kit that is all the same except that it is all dacromet use # K2HR35D. For E-Coat, which is basically black powder coated parts, use # K2HR35E. And for a raw finish use # K2HR35.

This kit and the Titan kits are both great and you wouldn't go wrong with either, I would consider both brands to be about equal. But you will first want to verify that this kit will fit the spindles of your trailer. You will need to pull the hubs and get the bearing numbers to do this. The inner bearing will need to be L68149 and the outer will need to be L44649....

If you pull the hubs off of your trailer and get the bearing numbers (inner and outer) and they happen to be L68149 for inner and L44649 for outer this kit # K2HR35D would fit and work well for you.

  • Actuator Recommendation for a Triple Axle Trailer Going from Drum Brakes to Disc Brakes
  • Some drum brake actuators can have the check valve removed or punctured to allow it to function disc brake setups, but this won't work for a triple axle brake setup because drum brake actuators just don't have the volume to activate the disc brakes.

  • What Direction Should Disc Brake Calipers Face

The important thing to consider when installing the calipers is to make sure at least one bleeder valve is pointing up and above the brake line fitting. The reason for this is to let air escape if it gets trapped in the caliper when you are bleeding the brakes. I have attached an installation video on a trailer that was upgraded...

If you're above 1/2 the weight of the vehicle, I'd rather see you go with disc brakes, due to their increased performance.
