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 stainless steel to prevent flexing and rust. 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 coated with corrosion-resistant dacromet 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.

  • 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 up...

  • Parts Needed to Install Disc Brakes on 2019 Grand Design Solitude 310GK
    We have the Kodiak Disc Brake Kit part # K2HR712DS which will work great for the hub/rotor parts on the 7k axles of your 2019 Grand Design Solitude. This is correct bolt pattern, capacity, and is dacromet and stainless steel so it will do a great job resisting corrosion. Then for everything else that you'd need to make the conversion the Hydrastar kit part # CAR-HBA16-2 is the way to go as it gives you the highest quality and fastest reacting actuator as well as everything else needed...

  • Will Kodiak Disc Brake Kit Replace UFP Brakes On 5,200 Lb Torsion Axle
    The correct Kodiak Disc Brake Kit for a 5,200 lb axle is part # K2R526S for stainless or part # K2R526D for dacroment. In regards to compatibility, the brake mounting flange and spindle size are the only factors we can confirm. I don't foresee any issues but test fitting would be the only way to confirm. There are no exclusions for torsion axle trailers in general.

  • 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?...

  • Parts Needed to Add Electric-Over-Hydraulic Disc Brakes to a 2019 Grand Design Solitude 375RES
    To replace the electric brakes on your 2019 Grand Design Solitude 375RES you will first need disc brakes. For your 7K axles I highly recommend the Kodiak Disc Brake Kit # K2HR712DS because it has a dacromet coating and stainless steel calipers which gives them great corrosion resistance. The kit includes enough parts for brakes on 1 axle so you will need 2 of them. For brake lines I recommend the HydraStar Hydraulic Brake Line Kit # HS496-252 which gives you a steel main line but then...

  • What Size Axle Will the Kodiak Disc Brake Kit # K2HR712DS Fit
    The Kodiak Disc Brake Kit # K2HR712DS is compatible with 7,000 lbs axles that have #42 spindles. These spindles use inner bearing # 25580, outer bearing # 14125A, and grease seal # RG06-070. All of these can be found in the bearing kit # BK3-200. As long as your axle and spindle falls within these parameters then you can definitely use this disc brake kit. Be sure that you are using an actuator that is compatible with disc brakes.

  • Is Swapping to Disc Brakes Beneficial For a 2010 Keystone Laredo 5TH Wheel?
    For your 2010 Keystone Laredo 266RL a Disc Brake trailer brake upgrade would provide you will a lot better stopping power. You would need to remove your current brake assemblies and hubs. The disc brakes will also require some modification to your trailers braking system. You will have to use an electric over hydraulic brake actuator which may require a different brake controller and run brake lines that will need to be filled with brake fluid and properly bleed. The benefits are that...

  • Availability Of Oil Bath Hubs For Boat Trailer With 7000lb Axles
    There are a few options for oil bath hubs for a boat trailer with 7000lb axles though I will start with saying that oil bath hubs are not recommend for a boat trailer due to the oil braking down very fast when water is introduced unlike grease. The first is a disc brake option which is the Kodiak Disc Brake Kit - 13" Hub/Rotor - 8 on 6-1/2 - Dacromet and Stainless - 7,000 lbs # K2HR712DS. This system includes races but you will need inner bearing # 25580 and outer bearing # 14125A. Now...

  • 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,...
