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.


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 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 disc brakes on my 38 foot 5th wheel travel trailer due to the poor brake quality of the manufacturer. I now drive on the highway with much greater confidence for our safety. The stopping power of these brakes is incredible. The quality of the brakes are superior. I installed them myself finding the instructions accurate and easy to follow. There was a small part missing out of the brake line kit and the part was overnited to me by E Trailer. I have purchased many items from this company and have found the products to be of top quality and fairly priced. The customer service is outstanding. Thank you. 306365

I just received the product. It arrived in excellent shape. I ordered it on Sunday and it arrived today Wednesday Great. I will be installing the brakes on a 16 foot gooseneck dump trailer that is used every day. I'm tired of working on electric brakes. 184180

Do you have a question about this Trailer Brake?


  • Oil Bath Seals for Kodiak Disc Brake Kit for 7K Axles and 8 on 6-1/2 Bolt Pattern
  • Yes, using oil bath hub seals # 10-63 will work with the Kodiak disc brake kit you ordered, # K2HR79E. The kit already has the oil caps so you wouldn't need those. The brake kit does not include the bearings. You would need 2 of # 25580 and 2 of # 02475.

  • Can I Use HR79 Brake Assembly with 02475 OB if Fifth Wheel has 14125A Bearings and a #42 Spindle
  • I reached out to my contact at Kodiak and they advised me that the Kodiak Disc Brake Kit 7,000 lbs # K2HR712D takes ½” studs only. When you go to 9/16” studs, the 7k axle kit # K2HR79DS comes with an 8K hub that takes that only takes the # 02475 bearing. Because you cannot fit 9/16” or 5/8” studs in a 7K hub Kodiak switches it to a 8 K hub. The 6K, 7K, and 8K spindle is the same spindle, the only difference is the outer bearing changes.

  • Recommended Disc Brake Upgrade Kit for 2014 Heartland Big Horn 3010RE 5th Wheel Trailer
  • The Kodiak Disc Brake Kit - 13" Hub/Rotor - 8 on 6-1/2 - E-Coat - 7,000 lbs # K2HR79E or the Kodiak Disc Brake Kit - 13" Hub/Rotor - 8 on 6-1/2 - Raw Finish - 7,000 lbs # K2HR79 will work with the #42 spindles that are on 6K Dexter axles. Both of these options have the 9/16 lugs just one has the e-coat for corrosion resistance. I've attached videos to further assist with product information and installation.

  • Recommended Disc Brake Hub Kit To Use With Kodiak XL ProLube Kit
  • The Kodiak XL ProLube Kit, part # XLPROLUBE2440KIT is not a fit on the # K2HR712 disc brake kit you mentioned because the hub is not threaded on the # K2HR712. I do have a solution that will work for you. I recommend part # K2HR79. This kit will fit the same size spindle, has threaded hubs which will work with the lube kit, and is rated for the same size wheels as the # K2HR712. The only difference is the size of the wheel bolts. The # K2HR79 has 9/16-inch bolts, where the # K2HR712...

  • Disc Brake Kit Recommendation for a Dexter 7,000 D-70 Trailer Axle
  • I did some checking and your Dexter D-70 axles have the number 42 spindle on them which is what the Kodiak Disc Brake Kit # K2HR79 that you referenced is designed to fit so it would work well for you. You will need to supply new bearings though. For that you would want the part # 25580 for the inner bearing and part # 02475 for the outer bearing. You should note that this outer bearing will be different from the one you pull out of your current hubs. Everything else will match right...

  • Will the Kodiak Electric Brake Kit Fit on the Timberen Axle-Less Systems
  • The Kodiak Disc Brake Kit # K2HR79 will fit on the Timbren Axle-Less Suspension System # TASR7KS01 as both are rated for the same weight capacity of 7,000 lbs. and have the same bearing inner diameters. The bearings and grease seal are not included with the Kodiak Disk Brake Kit, you will need to buy these separately. Bearings: Inner: # 25580 Outer: # 02420 Seal: # RG06-070 I recommend the Timbren Axle System as each unit operates independently and fits any trailer frame...
