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 4-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 brakes work very good, I feel much safer with these disc brakes than I did with the old drum type. I’m having trouble getting pictures but hopefully this from your work.

Great, you feel better going down the road when you know you you are in control.

I have been wanting to put discs on a tandem axle 16k gooseneck tilt bed trailer we use to haul a 10k tractor and 9k skid steer. i have been wanting to put these on for years. Tired of the electric brakes not working after they repeatedly fail and when they do work, it is only for a couple of weeks. They require frequent adjusting to have piss pour performance. I am looking forward to having dependable brakes, no more adjusting and the trailer brakes actually participate in stopping the trailer. They appear well built and are heavy duty, substantial metal.
I have a 10 ton dump and 30ft 10 ton flatbed that I will do next.



by:

Fits well. Should be nice upgrade. Verified lug pattern was correct



by:

One of the hubs shipped to me actually had larger and longer studs which differed from the rest of them. I had to purchase other ones locally and replace them to make them work. Otherwise, the order was great. Just wish the boxes would come more intact as they were mostly broke even inside the bigger boxes, the smaller boxes inside were broken.

I will have our customer service team reach out to you.

Everything was complete and easy to follow instructions. Single person job, took me 2 days to install the complete system. 1st day was the four rotors/calipers, 2nd day was the pump, lines, and bleeding the system. Easily could have been a 1 day job if all the tools were in place and a bit more dedication. Road test hasn't been completed as yet but experience with disk brakes on a previous trailer give me great confidence that it will be better than the electric I removed.

  • Recommended Disc Brake Conversion Parts for a 5th Wheel Trailer w/ 8,000 lbs Axles
    I would be happy to. Since your 2019 Heartland RV Landmark has 8,000 lbs axles you will need the Kodiak Disc Brake Kit item # K2HR89DD. These will replace the hubs and drums you have with rotors and hubs. The mounting brackets will attach to the flanges you already have. These are dacromet-plated rotors that have a 8 on 6-1/2 bolt pattern. You will need one set per axle. For an actuator, brake lines, and a breakaway kit you will want the Hydrastar Electric Over Hydraulic Actuator Kit...

  • Best Parts Needed to Convert 2014 Montana Fifth Wheel to Electric Over Hydraulic Disk Brakes
    Disc brakes have to have a hydraulic element to activate them which means there isn't strictly an electric only option. What you'll want is an electric over hydraulic setup which gives you the adjustability of electric brakes but also the stopping power of hydraulic disc. Since we know you have 8,000 lb axles I don't really have any additional questions so what you'll want is the kit part # K2HR858DD if your current wheel studs are 5/8 inch or part # K2HR89DD if they are 9/16 inch and...

  • Hub/Rotor or Slip-On Rotor for 2018 Cedar Creek 38EL to Convert to Disc Brakes
    The slip on kits like the part # K71-635-92 that fit your Dexter 8k axles have the benefit of rotors that are easy to replace going forward since you don't have to replace the hub at same time. Like with this kit you could replace rotors in future with part # K71-631-00. Or the hub/rotor kits like the part # K2HR89DD will work great too but replace rotors will require new hubs too. It might be best to look at how long you plan to keep the camper and go with which makes more sense. If...

  • Converting 8K Axles on 5th Wheel From Drum Brakes to Disc

This will replace the hub/drums you have with rotor/hubs and the mounting brackets will attach to the mounting flanges you have. These are dacromet-plated rotors and the needed 9/16" bolts are included. Use the HydraStar Marine Electric Over Hydraulic Actuator w/ Breakaway and 7-Way RV Harness, # HS381-9067.

    For a Lippert 8k axle we have the Kodiak Disc Brake kit part # K2HR89DD as a confirmed fit which comes with everything needed for a single 8k axle. You'll also need bearings # 25580, # 02475, and grease seal # RG06-070. Then for an actuator kit that includes the quickest reacting and most reliable actuator as well as the needed brake lines and a breakaway kit you'd need the part # HBA16-252-82.

  • Disc Brake Kit that Fits 8k Lippert Axle of 2020 Crossroads Redwood
    For your 8,000 lb Lippert trailer axle the Dexter 8k kit from Kodiak part # K2HR89DD would fit and work great. The AL KO setups are a little different so that would not be the route for you to go. Since this isn't an ABS system there isn't a tone ring. The # K2HR89DD is Dacromet coated which offers great corrosion resistance without being nearly as expensive as stainless steel.

    We have all of the parts needed to convert an 8k trailer axle to disc brakes but we don't have it as a single part number like we do with some of the other axle capacities.

For that you'd want the Hydrastar kit part # HS481-8067 which also comes with the breakaway kit, battery and wiring needed. Then you'll need the brake line kit part # HS496-252.

  • What Size Brake Lines Do I Need for a Kodiak Disc Brake Kit?
    The Kodiak Disc Brake Kit item # K2HR89DD uses a 3/16" brake line with a 1/8" ID. These lines paired with the correct actuator will provide adequate pressure to engage your braking system. I recommend the HydraStar Electric Over Hydraulic Actuator Kit for Disc Brakes item # HBA16-252-82. This is the quickest reacting and most reliable actuator and comes with a breakaway kit.

  • Converting A Toy Hauler With 8K Axles Over To Disc Brakes
    Hello Mike. Generally, the 8K axles will use the 12-1/4" diameter x 3-3/8" wide brake shoes. The 7K shoes will be 12" x 2". If your toy hauler is equipped with the 12" x 2" brakes, they technically are under-rated for the axle. Depending on your GVWR this is not necessarily a huge concern. It is possible to convert an 8K axle to disc brakes. Disc brakes provide more effective braking, and they are much more durable and weather resistant. In order to convert your RV to disc brakes, you...
