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.


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.

Excellent parts, easy assembly.


Last year, I had to rebuild my Myco triple axel trailer that sits under my 47' Fountain. Needed all new hubs, bearings, brakes, etc. Bought everything from for a 1/3rd of the price that Myco wanted to charge me. Everything was perfect and their customer service was excellent when I had questions. Had some parts that got damaged in transit, but they shipped replacements immediately with no questions asked. The Dacromet brake kits have held up well a year later despite being used in salt water about a dozen times. Very happy with this product.




Outstanding customer service.Judy M.and Cathy T. called number of times to make sure that I was happy with my order!!! I buy a lot of things on the internet and no one even compare to the service etrailer provides. Thank you !!!


Arrived as expected. Appear to be superior to the tie down calipers I'm replacing

  • What Replacement Disc Brakes do I Need for My TDE46890 System?
    As far as the labeling of the Kodiak Disc Brake Kit - 13" Rotor - 8 on 6-1/2 - E-Coat - 9/16" Bolts - 8K Dexter Disc Kit # K2R89DDE, Dexter is the parent company of Kodiak. The reason this particular kit calls out Dexter is anything above 7k axle is usually very specific on which brake kit fits. In this case this on works with Dexter 8,000lb axles.

    We offer and sell more Kodiak disc brake products than other brands and our customers consistently rate these Kodiak kits very highly.

We do not offer Dexter disc kits. You can refer to the linked article for explanation of the items needed to complete a conversion...

  • Recommended Disc Brake Conversion with Rotors Only for 7k Axles
    We have what you're looking for; check out the Kodiak # K2R712E which are designed to slip onto your existing hubs with 1/2" studs. These disc brakes are 13" and work with hubs that have 8 on 6-1/2" bolt patterns. There are also dacromet plated rotors available like the # K2R712DAC, which are great if you're using the trailer in an environment that sees a lot of moisture, since they'll provide superior rust resistance. Since you'll be converting to disc brakes, if you don't already have...

  • Compatible Parts to Convert Lippert 7K Axle to Electric Over Hydraulic Brakes
    Your Lippert 7K axle would use a 25580 inner and an 14125A outer bearing, so the # 42865-KIT hub you'd looked at would be compatible. The Kodiak # K2R712DAC slip-on disc brake kit is compatible with the 8 on 6-1/2 inch bolt pattern used by the hubs you'd chosen and the 5 bolt caliper mount is compatible with the bolt pattern on the brake mounting flange on your axle. The # HS496-252 brake line kit looks to be a good choice. The Titan BrakeRite I Plug and Play Electric-Hydraulic Actuator...

  • Recommendations for Brake Upgrades on 2015 Grand Design 375RE 5th Wheel
    If you wanted to stay with the electric brakes, and simply swap out your existing brake assemblies for self-adjusting brake assemblies, which would be # AKEBRK-7R-SA for the passenger and # AKEBRK-7L-SA for the driver's side. These brake assemblies are compatible with 12 x 2 inch brake drums (inside diameter x inside depth) which is what a 7000 lb axle would usually use. Given your wheel bolt pattern, you most likely have a 7000 lb axle. You'll want to consult the label you described for...

  • Disc Brake Kit for 2020 Grand Design Solitude 390RK with 7k Axles
    The only thing your missing potentially is idler hubs for the Kodiak disc brake kit part # K2R712DAC to fit on which for that you'd want the # AKIHUB-865-7-2-EZ-K which comes with bearings so you would not need a bearing kit. The Hydrastar actuator part # HBA16 is the best around so that's a good choice, and the brake line kit part # 20TA-BLKIT would work as well. Instead of the HBA16 though we have a kit that includes all of the needed electrical components as well which for that you'd...

  • Dexter 4" Drop E-Z Lube 7,000lb Trailer Axle With 8 on 6-1/2" Lug Pattern
    The Dexter Trailer Axle Beam with 4" Drop E-Z Lube Spindles # 8327860 does not include any hubs. You can add hubs to make it an 8 on 6-1/2" lug pattern. The Dexter Trailer Hub and Drum Assembly # 42866UC3-EZ contains the correct bearings, races, grease seal, grease cap and lug nuts for an 8 on 6-1/2" lug pattern with 1/2" studs. To complete the axle and brakes you will need 2 of these hubs with a Dexter Nev-R-Adjust Electric Trailer Brake Kit # 23-464-465. This brake kit is self adjusting...

  • Timbren Axle-Less Suspension System Compatibility with Aluminum I-Beam Trailer Frame
    The Timbren Heavy-Duty Axle-Less Trailer Suspension - 4" Lift Spindle - Off-Road Tires - 3,500 lbs # ASR35HDS02 is compatible with I-beam frames and in tandem axle configuration. Due to the Aluminum frame, I recommend putting a thin rubber pad between the steel mount and the aluminum I-beam. The powder coat on the steel should keep the two dissimilar metals from galvanic corrosion, but a thin rubber pad would drastically increase this safety. Zinc plated hardware will work well with...
