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 nickel-chrome-plated 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 Dexter's 7-bolt brake flange configuration, 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.

Note: These kits will not fit Dexter axles that came from the factory with Dexter disc brakes. They will only fit axles that come with drums or idler hubs.

  • How To Convert a 2019 Kaufman Trailer with Dexter 10K Axles from Electric Drum to Hydraulic Disc
    I have listed for you below parts you will need to convert a trailer from electric drum to hydraulic disc using an electric over hydraulic actuator. If you prefer a certain brand, just let me know what that is but there are not exactly a ton of options to choose from. I have attached the best for you.

  • Replacement Disc Brake Kit for a Dexter 12K Axle
    The correct Kodiak Disc Brake Kit for a Dexter 12K Axle is part # K2R1258L12, not part # K2R1058D11E. I spoke with Dexter and they stated the latter would only work if you have a Dexter Hub 008-430-03. It looks like the brake mounting flange bolt pattern, rotor diameter, and calipers are the same between the above two kits but I again would not be able to confirm direct compatibility unless using the Dexter Hub 008-430-03.

  • Which Disc Brake Kit is Needed to Convert 2006 Big Tex Gooseneck Trailer
    Due to the age of your 2006 Big Tex gooseneck trailer the kit you need to convert your axle to disc brakes is the part # K2R1058D11HD since this kit fits Dexter axles made prior to 2009. Then for an actuator kit the best option is the part # HS381-9067 as it gives you the most reliable and quickest reacting kit plus all of the electric components needed as well.

  • Torque Specs for Spacer and Caliper Bolts on Kodiak Disc Brake Kit # K2R1058D11E
    I reached out to my contact at Kodiak regarding the Disc Brake Kit # K2R1058D11E and he said the rotor/spacer bolts need to be torqued down to 90 foot pounds and the caliper clip bolts will be torqued down to 45 foot pounds. I have attached a video review and the written instructions below that you can also check out.

  • Recommended Complete Disc Brake Conversion System For 10,000 lb Dexter Axles
    To replace your leaking seals, you will want the Unitized Oil Seal # 10-51. This is a confirmed fit for your hubs. I've attached a video of an oil seal installation on a similar hub to help. For your disc brake conversion, you will need to use the Dexter Trailer Hub Assembly - 9,000-10,000-lb Axles - 8 on 6-1/2 - Oil Bath # 8-288-3UC1 and then the Kodiak Disc Brake Kit - 11" Rotor - 8 on 6-1/2 - Raw Finish - Leaf Spring - 10,000-lb Dexter # K2R1058D11E compatible with these hub assemblies...

  • Parts Needed to Install Disc Brakes on Gooseneck Trailer with 10k Axles
    Since we know you have 10k axles that makes picking out the disc brake kit easy. For that you'd need the part # K2R1058D11E but you'd need to have idler hubs installed already like # 8-288-3UC1 as this is a kit designed to slip over idler hubs. If you the plan is to go to electric over hydraulic brakes you'll need an actuator as well. For that the HydraStar brand is the way to go. For that the part # CAR-HBA16-2 comes with everything needed to install including brake lines so you'd be set.

  • Will the Kodiak Disc Brake Kit Part # K2R1058D11E Work on Torsion Axles
    I have the solution you are looking for, however the Kodiak Disc Brake Kit - 11" Rotor - 8 on 6-1/2 - E-Coat Finish - Leaf Spring - 10,000-lb Dexter part # K2R1058D11E wil not work on torsion axles. There just isn't enough room for the hardware to fit between the brake flange and frame. Instead you want to use Kodiak Disc Brakes - 13" Rotor - 8 on 6-1/2 - Raw Finish - Torsion - 10K Dexter and Lippert part # K2R1058D13. This kit is designed specifically for use on your axle.

  • What Does Kodiak Disc Brake Kit Fit
    The Kodiak Disc Brake Kit # K2R1058D11E will only fit a very specific idler hub from Dexter, the Dexter 008-430-03 and is designed for 16" dual wheels and has an 8 on 6-1/2" bolt pattern. Without seeing your specific application I can only guess but it sounds like this is not what you have on your trailer so you should definitely make sure you find out your precise axle and hub. While we do not have a video specific to this kit at the moment I did link a video which displays how a disc...

  • Parts Needed to Convert Dually Dexter 10k Trailer Axle to Electric Over Hydraulic Disc
    Since you have dually Dexter 10k axles with wheels larger than 16 inch you'd want the Kodiak Disc Brake Kit part # K2R1058D11E which is correct for this axle capacity and type. When it's time to pick out an electric over hydraulic actuator I would highly recommend the Hydrastar kit part # HS381-9067 as we have found it to be the most reliable kit out there that also reacts very quickly as well.

  • Parts Needed to Switch from Surge Disc Brake Actuator to Electric Over Hydraulic
    To switch from your current surge brake system to an electric over hydraulic system you'll need an EOH actuator, a brake controller and possibly a new coupler; you'll also need to re-wire the trailer so that it has a 7 way plug. Additionally, if you don't already have a 7 way plug on your tow vehicle, you will need to add one using a kit like the # ETBC7. For the actuator you can use the HydraStar Electric Over Hydraulic Actuator for Disc Brakes - 1,600 psi # HBA16, which is designed...

  • Best Electric Actuator Kit Recommendation for Boat Trailer with Surge Brakes
    You are on the right track, but as long as you are able to find the axle capacity you want in a grease hub setup there's no advantage to going with an oil-bath setup. The big factor for me is that if you blow a grease seal you'll be able to get home no problem and fix it without further damage. With an oil bath setup if you blow a grease seal you basically have to stop where you are at and fix the hub otherwise you'll start causing damage. Reason being that the oil is going to drain out...

  • Which Disc Brake Conversion Kit For 10000lb Dexter Axle Made In 2020
    For your 10000lb Dexter oil bath axle made in 2020 you will need to go with the Kodiak Disc Brake Kit # K2R1058D11E since your axle uses leaf springs, and is not a torsion axle. This will work with dual 16" wheels so you will need to make sure that is what your trailer currently uses. You will need to use Dexter Axle Oil Hub # 008-430-03 for each spindle to allow you to install the above kit unless you already have idler hubs. For an actuator to control these new disc brakes I recommend...
