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.

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!

This has been the best thing I could have ever done! Works fantastic!



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.

Patrick B.

5/28/2013

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

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!

Best thing you could ever do to a trailer, why these are not standard on trailers i have no idea
Smoother braking and emergency stop don't lock up as easy.

  • Recommended Electric Over hydraulic Actuator For Disc Brakes On Tri-Axle Car Hauler
    Adding electric over hydraulic brakes on your Kaufman trailer can give you a better braking system than hydraulic surge or straight electric brakes. If you have hydraulic surge brakes on the trailer, you will either need to replace the surge coupler or lock it so the surge feature is not active. The hydraulic actuator I recommend for your trailer is the Titan BrakeRite I Plug and Play Electric-Hydraulic Actuator Kit, part # T4813102. This actuator features 1500 hydraulic psi, and should...

  • 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.

  • Electric Over Hydraulic Disc Brake Kit Recommendation for AL KO 6k Axles
    Thanks for getting me the information I would need to help you pick out a disc brake kit. I was able to determine that you have inner bearing 25580 and outer bearing 14125A so the kit you would need would be the part # K2HR712. You would need two of these kits for all of your axles. For a tandem axle brake line kit you would want the part # DM5425 and for an electric over hydraulic actuator we like the Hydrastar the best here, part # HBA16.

  • Disc Brake Kit for 5th Wheel Trailer That Uses 8-Lug Wheels on 6000-lb Dexter Axles
    The key to selecting disk brakes for your 5th wheel is to match up the bolt pattern (in your case 8-on-6-1/2) as well as the brake flange mounting hole pattern, bearing set and axle weight capacity. It is fine to use a brake kit rated higher than your axle capacity, but never one rated lower. You need to match your hub's bearings to the new kit to ensure that the hub/rotor assemblies will fit your spindles. The Kodiak Disc Brake Kit # K2HR712 that you referenced has the bolt pattern and...

  • Are Disc Trailer Brakes Wider or Narrower than Drum Brakes When Considering Frame Clearance
    Disc brake setups in general are smaller than drum brakes. Drums need to be wide to allow as much contact for the shoes/pads of the assemblies but since disc brakes squeeze a rotor that turns they don't have to be as wide to be as efficient. So basically if you have clearance now for drum brakes going to a disc brake kit like the # K2HR712 would also clear.

  • What Disc Brake Conversion Kit Do I Need For My 14' Cargo Trailer?
    There are a couple of things I recommend you check for first before you decide on switching your whole setup first. What I recommend you do is check for a broken spring, a faulty adjuster screw, or even possibly a pinched wire. If any of these items are damaged, this may be causing your brakes to loosen. If not, and you're wanting to still change your setup, then I recommend converting your brakes with an electric over hydraulic disc brake kit. In order to determine which disc brake...

  • Difference Between Kodiak Disc Brake Kit # K2HR712 and # K2HR712E
    The difference is the finish of the rotors. The part # K2HR712 has a raw finish which is the most susceptible to corrosion. The # K2HR712E has an E-coat which is like a powdercoat that helps prevent corrosion.
