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.

These items were ordered to convert an older boat trailer from air over hydraulic drum to electric over hydraulic disk on a triple axle set-up. Great stopping power, oil bath hub, 9/16” studs, and dacromet coated. This set-up is for a speed boat that goes in and out of salt water as well as fresh water all the time. Choose oil bath huds because they seem to keep water out better than regular grease huds plus also seem to hold up better and provide greater mileage between bearing service than grease bearings.

I installed this product on my fifth wheel RV about a year ago. I tow with a f350 drw truck and was always concerned with the way it stopped. Now there are no issues. Best upgrade I have ever made. Product was excellent. Product arrived as promised. customer service was great. Thanks etrailer

I purchased most all my materials to put Disc Brakes on my 2011 Heartland Big Country from etrailer.com. I ordered Rotors, Calipers,Brake Hose's, Bearings, Seals and Spare Brake Parts from them. What a wonderful experience that was. The customer service was unbelievable. If I had a question I always received the correct answer. I had a couple returns because of mistakes I had made in ordering, and they were handled quickly and courteously. I highly recommend etrailer.com If your smart, you will explain to the customer representative what you are trying to do, and they will lead you down the right path the first time. Enjoy the experience, I did. This is a first class company with first class employees. Don't be afraid to order from this company. Gary

This has been the best upgrade I have done in the 7 years Ive owned this trailer, bar none.If you are contemplating a disc brake upgrade, spend the money you will have no regrets.Spend your time and money like your life depends on it, because it really does.Gary

Replaced my electric drum brakes with E/H disc, what a difference. I had to turn the brake controller way down. One year later: still very happy with my switch to disc brakes.

- K2HRCM1337-9DAC

these were installed on my Landmark fifth wheel. you have to know what you are doing to install the hydraulic brake actuator and hydraulic lines. But WOW what a difference. I think that my Landmark has more braking power than my pickup truck now. thanks

Great Disc Brake System replacing electric magnetic drum brakes on my triple axle Toy Hauler.

  • If Trailer Has Breakaway Battery Installed Will it Work with Electric Over Hydraulic Disc Actuator
    If your trailer already has a breakaway battery designed for electric brakes already you would not need to purchase an additional setup. You would need the disk brake kit like the part # K2HRCM1337-9DAC that you referenced, an actuator like our favorite Hydra Star # HBA16, and a brake line kit like # 18TA-BLKIT and you would be on your way. I attached a help article that covers adding EOH brakes to a trailer for you to check out as well.

  • Disc Brake Kit Recommendation for a 2006 Landmark Fifth Wheel Trailer
    The races are included with the # K2HRCM1337-9DAC, but the bearings and seals are sold separately. For bearings you would need the # 25580 and # 14125A and for seals you would the part # RG06-090 that you said that you have. This would work well with the Hydrastar Kit part # CAR-HBA16-2 as well.

  • Does Kodiak Disc Brake Kit K2HRCM1337-9DAC Include Oil Bath Caps?

You will however need to purchase the bearings, and grease seals separately as they are not included. The # K2HRCM1337-9DAC uses inner bearing # 25580, outer bearing # 02475, and oil bath seal # RG06-090. I included a few videos of the # K2HRCM1337-9DAC for you...

    I would be happy to piece a kit together for you, but we do not currently have a HydraStar Disc Brake Kit W/ Actuator for 7000lb axles that has 9/16" studs. To get this you will need two of the Kodiak Disc Brake Kit - 13" Hub/Rotor - 8 on 6-1/2 - Dacromet - 7,000 lbs # K2HRCM1337-9DAC which is the correct kit for your 7000lb axle, and has the 9/16" wheel studs you wanted.

    To change your electric brakes on your Kaufman trailer to an electric over hydraulic (EOH) system you will need to hydraulic brakes, brake lines, an EOH actuator, a breakaway kit (which you should already have), and a brake controller (which you should already have).

  • Trailer Axles and Electric Over Hydraulic Disc Trailer Brakes that Offer Best Ride for 14K Trailer
    For a 7,000 pound trailer axle I recommend a Timbren system, # TASR7KS01. This is actually an axle-less system with its own built in suspension. Since there is no axle beam connecting one side to the other it creates independent suspension at all the wheels. For 2 axles you would need 2 kits. For compatible disc brakes I recommend Kodiak dacromet disc brake kit # K2HRCM1337-9DAC. This kit is for 1 axle so to put brakes on both axles you would need 2 kits. For as much weight as you are...

  • Parts Needed to Change Electric Brakes on a Tandem Axle Trailer to Electric-Over-Hydraulic Disc
    For a disc brake assembly I recommend going with the Kodiak Disc Brake Assembly # K2HR712DS for 1/2" diameter studs or Kit # K2HRCM1337-9DAC for 9/16" diameter studs. Both of these kits are for 7,000 lb trailer axles. For the inner bearing use part # 25580, outer bearing use part # 02475, and grease seal use part # RG06-070. If you have two 3,500 lb axles on your trailers I recommend the Titan Disc Brake Assembly # T10HREKITBB (2 for each axle) which comes with inner bearing # L68149,...

These systems can be used to replace up to 2 axles and they have brake mounting flanges included. With this system you also will not have to worry about suspension components wearing out like you would with traditional leaf spring suspension. They are not oil bath types of spindles but they are EZ lube so you would just pump grease in at the end of each of the spindles so it...
