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 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.

After a lot of research with the help of etrailer support I purchased the Kodiak Disc Brake Kit K2HR712 and installed on a 2013 Dutchmen Rubicon 2900 with 7K lippert axles to replace the 13” Electric drum brakes. I discovered any questions about whether the disc hubs would fit my axle was eliminated when I realized I just had to verify the wheel bearing numbers for the disc hubs were the same as what was on my axles. (bearings, caps and seals do not come with the kit and need to be ordered separately).
My trailer had dual axles, the disc kits came in separate boxes that did fairly well in shipping, nothing poking out of the boxes or anything. Parts matched and fitted without any problems. Again, etrailer support was very helpful in getting the correct parts and any questions I had during the installation. I could have done this myself however I choose to have a brake tech do the hydraulic lines and bleed the system out. Very satisfied with the product and support. Tried to upload pictures but kept getting errors.

Kodiak disc brakes are great. They are still doing the great job they did from day one. these will stop the trailer during panic stop situations which was something I could have never counted on my elect brakes to do.



by:

The product was very good and fit as I thought. It would be important to ensure you get the right parts as not every trailer is the same. Also the Kodiak directions are terrible, if you know anything about brakes then it still should be easy, but there are a few things that need to be checked while installing

IM CONCERNED ABOUT THE SIZE OF THE WHEEL LUGS. I HAVE 916 STUDS NOW BUT THE KITS ALL COME WITH 1/2 STUDS. WILL MY 16 INCH ALUMINUM WHEELS STILL BOLT ONTO THE 1/2 LUGS? IM SWITCHING FROM ELECTRIC OVER TO DISC BRAKES.

It should not be a problem so long as you have the proper size lug nuts to match the studs on on the rotors. I looked at all of the 16 inch, 8 on 6.5, aluminum wheels that we carry and they are all either for 1/2-20 studs or they will work with both 1/2-20 and 9/16-18. We do not have any of these wheels that will only fit 9/16-18.

I put Kodiak disc brakes on my dump trailer I now have two trailers with disc brakes on them they work so much better than drum brakes a lot safer towing definitely worth the time and money



by:

Etrailer is your one stop shop! They have everything for your truck and trailers!! Shipping is fast and free and they have the best prices around!! Ordered a pair of disk brakes for my tailer and recived them a coupe of days before the estimated delivery date! About to order another pair! Not my first or last!

I couldn't be happier. Everything went together like greased lighting! Fit my Montana 3400RL perfectly! I am delighted. Everything has a nice backed on finish for an excellent product. I highly recommend it!

  • 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?...

  • 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...

You can check your existing bearing numbers to determine if this kit or another will fit your axle. If you have # 25580 inner bearings and # 14125A inner bearings, 16 inch or larger wheels with an 8 on 6-1/2 bolt pattern, this kit will work.

  • Max PSI For the Kodiak Disc Brake Kit # K2HR712 Before Seal Failure
    I spoke to my contact at Kodiak and he said that anything over 1,600 psi will void the warranty of the Kodiak Disc Brake Kit # K2HR712 but most likely the seals in the caliper would give out at about 2,200 psi.

    The center section of the hubs on the Kodiak Disc Brake Kit # K2HR712 that you referenced where the pilot hole of a rim would have to fit over is 4-3/4 inches. That would have to match you wheel perfectly if they are hub centric wheels. We do not offer rings to take up room there.

  • Caliper Installation Position Recommendation when Installing Disc Brakes on Trailer
    The calipers of the Kodiak Disc Brake Kit part # K2HR712 that you referenced can basically be installed in whichever orientation you like. BUT the key is to pick a location that will allow one of the bleeder valves to point up so that when you go to bleed the brakes the air will have an easier time traveling up the valve. Aside from that and clearance issues that may prevent them from being orientated in certain positions there really isn't any wrong way to orientate them.

  • Comparing Rotor-Only and Hub/Rotor Disc Brake Conversion Kits
    A slip-on type rotor-only disc brake setup like Kodiak 7K kit # K2R712 will indeed shift the wheels/tires about 1/2-inch further out from the trailer. This can in some cases cause tire-to-fender clearance concerns but the bearings really are not affected much so long as they are properly lubricated. The cost for rotor-only kits is often slightly lower than for hub/rotor kits like # K2HR712. Rotor-only kits are a good choice when you have hubs that are in excellent shape and that do not...
