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.

I've bought this disc brake kit a year ago and towed over 16K miles. THIS SYSTEM IS AWESOME! No more bucking and chucking or clanging or weak brakes. I tow with 2017 Ram 3500 4X4 and I can stop almost as fast with the trailer on as without. NO brake fade! No squeal! If you're still using electric brakes you're not safe. Totally worth the $$ and time.

Well, its been a little over a year and 14K miles since the install. This is the best thing Ive ever done for towing safety. Steep grades and panic stops are no problem. I let my brother-in-law drive my rig got a day and we did the install on his trailer ad well. He likes them as much as I do. These brakes SHOULD be mandatory on new trailers!



by:

Products were easy to replace the old drum system a slight mod was needed to shin out the caliper to line it up onto the rotor but all in all it was a simple replacement all five bolts were able to be secured great looking system.



by:

I changed out my electric drum brakes on my Montana fifth wheel with this hydraulic brake actuator and Kodiak discs rotor system . What a difference this new brake system has made. I can now lock down the trailer tires if needed and drive much more relaxed on the highway knowing I can stop on a dime.



by:

Easy installation and extremely dependable braking power! I use these on a. 33 foot, 16,000 pound flatbed for work. I have 60,000 miles on them and they’re still in great shape. Converting to electric over hydraulic wasn’t cheap, but it was the best investment I made! No brake fade at all, and the stopping power is incredible over the factory electric brakes.



by:

These parts are very heavy duty and fit perfectly on my Dexter 7K axles. The backing plates bolt on in place of the drum backing plates using the same bolts. Bearings, caps and seals are NOT included, but they are interchangeable with the drum brake system that it replaces so parts are readily available for any future repairs needed. At a minimum, you must order new grease seals because it's about impossible to get the old ones out without destroying them. I suggest ordering new bearings too so you aren't gambling on the old bearings still being serviceable. I didn't and lost my bet so I had to make an unscheduled visit to the local parts house where the prices aren't as good as etrailer. The Dacromet appears to be an excellent coating, but since everything is still new, it's too soon to say how it will hold up to the weather. The bolts come pre-treated with thread locking compound so no lock-tite required when installing the calipers.
I had one small problem where one of the brass hose fittings got smashed in shipping due to a combination of careless handling and insufficient packing. The caliper box has a protective pocket that looks like it's designed specifically to protect from this type of damage, but the rotors are heavy enough to defeat that feature when subjected to typical shipping company box banging. etrailer customer service handled this great and got a replacement caliper shipped out same day so I am very pleased with their support in spite of the temporary setback on getting to use my new brakes. I would like to see the kits packaged in a bit more padding and a heavier duty box that can stand up to delivery drivers. All 4 of my boxes were in pretty rough shape to include holes with parts protruding, but the only actual damage was one brass fitting.

So how do they work? Outstanding! I have pulled trailers with electric drum brakes for decades. I have never had a trailer stop itself anywhere near as well as this. In spite of the significantly higher cost for this system, it is well worth the peace of mind knowing that I can stop just as well with the trailer as I can without. I can't count how many times I've used bad words while trying to avoid a collision due to weak trailer brakes. Those days are gone! I plan to do the same upgrade to my other trailer too.



by:

Good kit and the disc brakes are a tremendous upgrade. The only thing I would wish is that they would include the grade 8 fine thread bolts to replace the backing plate studs that are too short.

  • Timbren Silent Ride and Disc Brake Kit Recommendation for Lippert 7k Axles
    The Timbren Silent Ride 7k system part # TSR7000T05 would be a great solution that doesn't quite break the bank like the MorRyde would. Then for a disc brake kit you'd want the part # K2HR712D which is a 7k kit that will fit your Lippert 7k axles well. You will also need the bearings part # 25580 and # 14125A for each hub and then seals too as part # RG06-070. This is a Dacromet coated setup which will fight corrosion well.

  • Disc Brake Kit Needed for a 2015 Cyclone 4200 with Triple Dexter Axles
    I reached out to my contact at Dexter Axle who gave me the spindle information for your specific axle. The compatible disc brake kit that I recommend going with is part # K2HR712D from Kodiak. My contact did mention that this axle originally came with electric brakes so you will need a brake line kit as well since it sounds like you already have an actuator. I have linked our available brake line kits. All you have to do is filter through the selection for the best fit for your trailer...

  • Recommended Disc Brake Conversion for 7,000 lb Dexter Axles
    On your 2018 Montana 3791 RD, with Dexter 7K axles, we do have the parts but not in a kit for axles that large. I recommend the Kodiak Disc Brake Kit - 13" Hub/Rotor - 7,000 lbs # K2HR712D along with Bearing Kit # BK3-100. I recommend using grease # L11390 and cap # F001520 instead of doing the oil bath simply because if a seal fails you can melt your bearings and cause more issues than what grease would allow. Then for the electrical aspects, I recommend the HydraStar Electric-Hydraulic...

  • Parts Needed to Upgrade From 7K to 8K Axle and Convert to Electric Over Hydraulic Brakes
    In order to change from an 7,000 pound axle to an 8,000 pound axle you will need to replace the entire axle with an 8K model. You will not be able to add any parts to your current axle to upgrade it to an 8,000 pound capacity. We do not currently have any 8,000 pound axles available but you will want to find one that features the same hub face and spring center length to what you currently have.

  • 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?...

  • Converting to Electric Over Hydraulic Disc Brakes From Electric Brakes on Trailer With 7K Axles
    There are a number of parts you will need to replace the electric drum brakes on your trailer, and though there is not an all-in-one kit I can let you know the parts you need, starting with a disc brake assembly to replace your current hub and drum. I contacted Lippert with the serial number from you axle and based off what they told me the the correct brake kit is the Kodiak Disc Brake Kit # K2HR712D which is for 7,000 lb axles and has an 8 on 6-1/2" bolt pattern for your wheels.

  • 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...

  • Converting Triax 5th Wheel Trailer with 7k Dexter Axles to Disc Brakes
    We have the Kodiak Disc Brake Kit part # K2HR712D which is the correct hub/rotor set for the 7k axles on your trailer. You'd need 3 of these for your trailer and then an electric over hydraulic actuator like the # HBA16 you mentioned. I would actually recommend the # HBA16-252-82 though as it comes with the breakaway kit plus enough lines for two of your axles. For the third axle you'd then want the part # 9579-01.

  • Correct Disc Brake Conversion Kit for 2022 Grand Design Momentum 397THS
    I recommend using the Hydrastar Disc Brake Kit part # HSE7K-TR1 for a 2022 Grand Design Momentum 397THS. This is a complete kit that has everything you need for the swap except brake fluid. It has the hub/rotors, calipers, brackets, lines, actuator, etc. The hub/rotor design also cuts down on extra parts and is easier to install/replace. If you want Kodiak specifically, the Kodiak Disc Brake Kit part # K2HR712D would be correct but you'd need multiple kits and several other parts.

  • Disc Brake Kit Recommendation for Lippert 7k Axles
    The disc brake kit # K2HR712D that you referenced should work well for you. You would need a quantity of 2 of these for each of your axles. These have the same bolt pattern as your current setup and are rated a 7k. You can verify that these will fit your spindle by removing a current hub and checking the numbers on the bearings. If they are 25580 for the inner and 14125A for the outer this kit would fit the spindle and work well. This kit will fit a spindle that has a diameter of 1.25...

  • Will A HydraStar Electric-Hydraulic Actuator Work With A 2011 Ford F-250 Factory Brake Controller
    The factory trailer brake controller in your 2011 Ford F-250 will have no issues at all working with the HydraStar Electric-Hydraulic Actuator w/ Line Kit for Disc Brakes # CAR-HBA16-2. It was just the controllers used in 2007 and 2008 Ford trucks that had compatibility issues, so you are good to go. I will say that wiring these can be on the difficult side though, so I highly recommend using a junction box, like the # 277-000141, if you do not already have one. One of the big pluses with...
