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 5-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. These are designed to fit the XL-Lube, the Never Lube, Nev-R-Lube by Dexter, and the XL-Lube 2 Hub. These have been designed with an 8 on 6 1/2" bolt pattern, available with 9/16 or 1/2" studs.Now the Kodiak disc brake kit is going to be the perfect solution for upgrading your camper from the standard traditional electric drum style brakes. These are going to allow us to use hydraulic pressure and just like the calipers on our cars, they're going to squeeze the rotors here. That's what's going to bring us to a stop rather than the shoes trying to push out. This is going to give us superior braking performance.

Also, something that's going to be much smoother. These are going to release better, relieving the tension so it's going to roll a little bit more freely but when it's time for the braking power, we're going to have everything we need, especially with this ceramic brakes that are here against our 13" rotor.Now the big advantage and the reason you're going to see most of the customers going with the disc brakes over the electric brakes is going to be simply because of the performance that you get out of them. The stopping power when using disc as compared to drum brakes is going to be drastically shorter, we're going to get stopped much more safely, much more quickly even with the larger loads that we typically have with our campers. Now this particular kit has the E-coat on it. It's going to be the black finish you see.

It helps to fight some of the properties that are sometimes in brake dust that cause corrosion. Caliper, caliper slides are the same way but if you want them in a raw finish, they're also available that way.These brake pads are designed just like automotive grade pads. We've got the chamfered edge here on the front that's going to reduce any of that chatter that we sometimes get. You've also got the springs here designed to hold the pads in place and keep them from moving around and those also are going to have a nice coating on them to help resist any corrosion. As we've said before, these are ceramic brake pads and ceramic brake pads, they tend to generate less dust and also give us better stopping power.

Also, you'll notice our rotors are going to be ventilated. That's going to help dissipate a lot of heat. The number one enemy of brakes is going to be heat. When they get hot, they start to work less and less so that helps to dissipate that, get that heat out of our rotors so we'll have better stopping power.Now this is designed to fit the 50 millimeter sealed bearing style hubs so we're looking at the XL-Lube, the Never Lube, the XL-Lube 2, any of those larger spindles or if they just slide on, this is going to be the perfect solution. Now the biggest difference you're going to have between the different sets available and the best way to tell if they're going to work on your trailer, of course, you're going to need to Never Lube, the XL-Lube, the hubs we've talked about but some of them have a 9/16" wheel stud, some of them have a 1/2".

It's going to be the biggest difference. The rest of the differences are really whether you're getting the E-coat or just the standard raw finish.There will be kits available for the 7000 or 8000 pound variety of axle as well. You're going to have everything you need for either braking components. All of your bolts, your hardware, and even the bracket to get this bolted onto your axle. A lot of times you're just going to reuse the existing axle hardware that was holding on the old electric brake so if those are damaged, be sure to get replacements.Now each kit's going to come with two of rotors. It's going to come with two calipers loaded with pads already. We're going to have caliper bolts that come with it and the mounting bracket. Also included will be the cap. Once you've got everything put together, knock that on there with a rubber mallet, that'll keep everything sealed up and keep that dirt and grime from getting inside.That's going to complete our look at the Kodiak disc brake kit designed for the XL-Lube, the XL-Lube 2, the Dexter Nev-R-Lube, and Never Lube hubs.

I put Kodiak disc brakes on my dump trailer I now have two trailers with disc brakes on them they work so much better than drum brakes a lot safer towing definitely worth the time and money 601621

- K2HR712

After a lot of research with the help of etrailer support I purchased the Kodiak Disc Brake Kit K2HR712 and installed on a 2013 Dutchmen Rubicon 2900 with 7K lippert axles to replace the 13” Electric drum brakes. I discovered any questions about whether the disc hubs would fit my axle was eliminated when I realized I just had to verify the wheel bearing numbers for the disc hubs were the same as what was on my axles. (bearings, caps and seals do not come with the kit and need to be ordered separately). My trailer had dual axles, the disc kits came in separate boxes that did fairly well in shipping, nothing poking out of the boxes or anything. Parts matched and fitted without any problems. Again, etrailer support was very helpful in getting the correct parts and any questions I had during the installation. I could have done this myself however I choose to have a brake tech do the hydraulic lines and bleed the system out. Very satisfied with the product and support. Tried to upload pictures but kept getting errors. 151073


Kodiak disc brakes are great. They are still doing the great job they did from day one. these will stop the trailer during panic stop situations which was something I could have never counted on my elect brakes to do.

The product was very good and fit as I thought. It would be important to ensure you get the right parts as not every trailer is the same. Also the Kodiak directions are terrible, if you know anything about brakes then it still should be easy, but there are a few things that need to be checked while installing 80365

It should not be a problem so long as you have the proper size lug nuts to match the studs on on the rotors. I looked at all of the 16 inch, 8 on 6.5, aluminum wheels that we carry and they are all either for 1/2-20 studs or they will work with both 1/2-20 and 9/16-18. We do not have any of these wheels that will only fit 9/16-18.

  • Switching from Electric Drum Brakes to Electric Over Hydraulic Brakes on Trailer w/7K Lippert Axles
  • I did some checking and your 7K Lippert axles use inner bearing 25580 and outer bearing 14125. We have 7K brake kit options that use these same bearings and have the same 8 on 6-1/2 bolt pattern as your existing hubs. The most basic kit is # K2HR712. The parts have a raw finish which means no corrosion resistance. The next step up from there is # K2HR712E which has an e-coat finish which is like a powder coat and offers minimal corrosion resistance. What I recommend is the next step...

  • Parts Needed to Convert Trailer with 7,000 Pound Axles from Drum Brakes to Hydraulic Disc Brakes
  • An excellent brake kit for your 7,000 pound axles is the Kodiak # K2HR712. You'll need inner bearing # 25580 and outer # 14125A. Also seal # RG06-070. These disc brakes have a raw finish and an 8 on 6-1/2 bolt pattern. Since you have a tandem axle trailer, # T4830000 will be the brake line kit for you. If you're going to install electric over hydraulic brakes, the HydraStar # HBA16 is a what we recommend for an actuator. If your brakes will be just hydraulic disc brakes, then use...

  • Converting Drum Brakes On A Dexter Military Trailer Axle With 8 On 6-1/2
  • I would be happy to help you choose the correct brake setup for your Dexter Torflex Axle, however there are no manufacturers that currently make electric disc brakes. All disc brakes are powered by a hydraulic cylinder. If you wish to use a disc brake setup controlled by an in-cab brake controller, you will want to consider the HydraStar Electric Over Hydraulic Actuator for Disc Brakes part # HBA16 and an electric brake controller such as the Tekonsha Prodigy P3 Trailer Brake Controller...

  • Converting Three 7,000 Pound Dexter Axles to Electric Over Hydraulic Brakes
  • I can certainly help you out with a disc brake set up on your trailer. The first thing we need to find out in order to select the correct parts would be the inner and outer bearing numbers stamped into the sides of the bearings in the hubs you have now. With that information I can ensure that we get you the right parts. I would also need to know the bolt pattern of the wheels and what kind of braking system the trailer currently has. Also, do all 3 of the axles have brake mounting flanges?...
