Kodiak Rotor Diagram

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.

Video Transcript for Kodiak Disc Brake Kit Installation

Today on our boat trailer, we'll be installing the Kodiak disc brake kit with ten inch hub and rotor, part number K2HR35D. To begin our install, we'll first need to remove the wheels, and then the old hub and drum assemblies. To remove the wheel, remove the lug nuts and secure it. To remove the hub drum assembly, we'll start by removing the dust cap, and underneath the dust cap there will be a cotter pin.Go ahead and pull the cotter pin, then we'll remove the castle nut from the axle. Once we remove the castle nut we can go ahead and remove the hub and drum assembly, leaving our old drum brakes and backing plate. For install we'll also need to remove this backing plate, which secures the wheel cylinder. We'll go ahead and remove the brake line from the wheel cylinder first.

After we remove the brake line, we can then remove the four fasteners that secure the backing plate to the axle. With our four fasteners removed, we'll go ahead and take the backing plate off and set it aside; it will not be reinstalled. However, do hang on to your hardware, because we'll be reusing that to secure the caliper bracket to the axle. We'll go ahead and put our caliper bracket on the axle now. Once again we're reusing the manufacturer's hardware, running our bolt through the axle, then through our caliper bracket, andsecuring with the locknut. Next, we'll need to install our new hub rotor assembly.

We'll be reusing the inner and outer bearing, washer, and castle nut from the hub drum assembly. Let's go ahead and start removing these items from our hub drum assembly. The castle nut we removed earlier, we'll go ahead and clean it up and set it aside. We'll repeat the same process with the washer that sits between the castle nut and the outer bearing. The outer bearing will be free, as it's only held in by the castle nut, so we can go ahead and take that out, clean it up also. To clean it up, we're just going to be removing some of the excess old grease.

For the inner bearing we'll have to flip the hub drum assembly over, and remove the grease seal. The grease seal will hold the inner bearing in to the brace on the hub drum assembly, and our hub rotor assembly. Once we have the inner bearing removed, we'll go ahead and clean it up, and then we're going to pack our bearings before we install them. To pack them we'll use a grease packing kit, drop the bearing in position and squish it with the cone, which will shove new grease up through the bearing, pushing out the old grease. We'll go ahead and take our packed bearing and put it on the inside of our hub rotor assembly, and then install the grease seal. We'll be using a seal driver assembly; however, a piece of flat wood like a two by four, that's large enough to cover the entire seal surface, will work in a pinch.

With our seal installed, we go ahead and put our new hub rotor assembly up onto the axle. We'll slide it back and seatit into place. Next, we'll go ahead and take our outer bearing and repack it also, the same way we did the inner bearing. Once it's been packed, we'll go ahead and put it over the axle, into the hub rotor assembly, and seat it intoposition. Then we'll follow with our washer and castle nut. We'll tighten the castle nut down to seat the bearings, and then back it off slightly, as you do not want extreme, constant pressure at all times for this style bearing. Once we have the bearing seated and our castle nut in place, which means that it will be lined up with the predrilled holes in the axle, so that we can slide our cotter pin through the castle nut, through the predrilled holes in the axle, out the other side of the castle nut, and bend the tabs over to secure it. With that secured, we're going to go ahead and install the new dust cap. This will also be the removable grommet to grease this particular axle, as it's an easy lube axle. Next, we're ready to install the caliper; however, this application, it will be necessary to thread the brake line directly into the caliper, so that can be done easier off of boat. Setting it on a flat surface, we'll go ahead and thread the brake line directly into the caliper and tighten it down. We'll go ahead and take the caliper, set it over the rotor into position, lining up the sliders with the predrilled holes in the caliper bracket, which we've previously installed. Once it's lined up, we'll put the sliders into place and tighten them down. Next, we'll need to connect our new flexible hose to the manufacturer's steel line. In most cases we'll go ahead and cut away a portion of the steel line that the hose will make up, reflare the line, mount it with a mounting bracket, and cut it at the necessary length. However, because of previous work done to this line, the inner nut on the brake line is not in the best shape, so we're going to go ahead and just replace it with a small section of new line. The new eighth inch line on this application can be purchased at your local auto parts store. This short piece of line will work perfectly to gointo the brake tee, here mounted into the axle. We'll go ahead and thread it in, and secure it. Next, we'll take our bracket, put it over the line, and thread the line into the hose. Once we have it started, we can then go and take the bracket, put it in position on our flexible hose, and secure it to the axle with our self-tapping screw. Once secured, we'll go ahead and put the mounting clip in place, which will hold our brake hose to the bracket. Once the clip is installed, we'll then go ahead and continue tightening down the line to the hose. With the driver's side done, we're going to go ahead and repeat the same process on the passenger's side. Note on the opposite side we will not have to replace the entire steel line. In these cases, we can simply cut the line as necessary to length. We'll take the nut that went into the back of the wheel cylinder previously, install it onto the line that will stay on the boat, and then redouble flare the steel line. A double flare kit can be rented or borrowed from your local auto parts store. Follow the procedures of the double flaring kit. Once the line's been double flared, we'll go ahead and repeat the same procedure of installing the bracket onto the line, threading the line into the hose, and then securing the bracket to the axle. Then tighten down the line to the hose. Secure the bracket clip that will hold the hose in place. With all our components installed, we'll need to bleed the air out of the braking system. To do this, we'll open up the bleeder on the brake caliper and remove the cap from the master cylinder, and we'll also make sure we have a full master cylinder. After a bit of time, the air will self-bleed out of the bleeder, assisting in getting the air out of our system. After you gravity bleed it, it's recommended to do a vacuum assist or manual power bleed. Once we've bled all the air out of the system, we're ready to hit the road. That will complete the install of the Kodiak disc brake kit, part number K2HR35D, on our boat trailer. .

My drum brakes locked up on me because it is a boat trailer and gets submerged in water. I hate drum brakes, due how many part are inside and can rust up. I am the 3rd owner of my 1998 boat trailer and it was hard to figure out what I needed to fix it. I contacted etrailer and they were super helpful, super informative and super easy to work with. I told them what I had, and what I wanted to do., and they put a package together for me and that was them. Everything was super east to install because it is all bolt on. I did have to do some cutting and grinding on my old tongue because the master was welded on. That was the only difficult part. My new setup is amazing and the disk brakes and new master make it feel like my boat is not even there. All in all, I am 110% satisfied and will definitely be a returning customer for any trailer needs. Thank you etrailer for making everything super easy. 635088

Product has performed flawlessly. It was an easy install with all the proper fittings and equipment and the printed instructions were easy to follow. We made a trip with it last fall through the mountains and never felt there was any issue with the trailer brakes on steeper down grades. Much better than the electric magnetic drum brakes I replaced. I would and have recommended this product to many travel trailer owners. 426002


Comments
The summer of 2018, we traveled to Alaska and put 15,000 miles on the trailer. The brakes performed as expected and we never felt that the trailer was pushing us when the brakes were applied. We crossed passes from 2500 feet to 12,000 feet with some 7-9 downgrades and felt completely confident in the stopping power. I continue to recommend that trailer owners should seriously consider replacing the electric brake systems on their RV trailers with electric over hydraulic disc brakes. Your safety will be enhanced and you will never regret the upgrade.

My AmeraTrail trailer came with this kit when built. Unfortunately the original owner did not pay any attention to the trailer brakes. One caliper was rotted out and leaking fluid atround piston. Other caliper piston seized. I bought this replacement kit from Etrailer and it arrived just as described and pretty quick. Replaced all old parts and new went on nice and easy. When bleeding calipers be advised the bleeders are a 2 piece design. Looking forward to having good trailer brakes again. 380125

We have had people with Shoreland'r trailer be able to use our hubs so I wouldn't think you would have a problem finding the right kit from us. I attached a help article on adding disc brakes for you to check out as well.

  • Aluminum Car Trailer Restoration and Replacement Brake Recommendations
    Thanks for the feedback, and I am glad that you are finding our website helpful! For your 1989 Trailex CT-7031 all aluminum trailer with the specifications that you provided there are three options for restoring or replacing the brakes for this trailer. The three options are similar to what you mentioned, and are: 1.Hydraulic Drum, which is the most cost effective. 2.Hydraulic Disc, which is more expensive, but provides better performance. 3.Electric drum, which is most cost effective...

  • Replacement Kodiak Brake Kit for UFP DB-35 Brakes on Trailer
    Based on my research, it looks like the UFP DB-35 Brake Kit is for 3,500 pound axles and uses the # L68149 inner bearing and # L44649 outer bearing. I highly recommend that you verify this by measuring the existing bearings or the spindle where the bearings sit. For a replacement Kodiak Brake Kit, the part # K2HR35D should be the correct assemblies. This kit includes 2 Dacromet-plated, 10 inch hub-and-rotor assemblies, calipers, and mounting brackets. They are designed for 3,500 axles...

  • Can Electric Drum Brakes on 5th Wheel Trailer be Converted to Disc Brakes
    You can certainly change to electric-over-hydraulic disc brakes on your Mountaineer Fifth-Wheel from its existing electric drum brake setup. I have attached a great article that details all the items you will need to make this conversion. You will need the disc brake assemblies themselves, a brake line kit, an electric-over-hydraulic actuator, and a brake controller that is compatible with electric-over-hydraulic brakes (if you don't already have one). In order to pick out the correct...

  • Can Drum Brake Actuator on Trailer be Reused with Disc Brakes
    Since drum brakes and disc brakes require different amounts of hydraulic pressure you'd have to swap out your coupler or if available switch the master cylider of what you have to be compatible with disc brakes. I'd have to see what coupler you have to see if we have a master cylinder for it. For a 3,500 lb axle though we have the disc brake kit from Kodiak part # K2HR35D which would work well. Aside from this and figuring out your coupler situation you'd be set.

  • Hot Rotors On Trailer With Surge Brake Coupler
    Disc brakes are constantly dragging on the rotor although with minimal drag when you aren't hitting the brakes or in this case applying pressure to the coupler to engage the pad pressure. They will run hotter than the non-braking hubs for sure. The temp at 147 degrees is not bad at all. When your reading gets to the 300 degree or more mark is when I'd be looking at a caliper issue as you may have a caliper that is stuck and engaged while driving.

  • Kodiac Disc Brake Kit Compatibility with UFP DB-42 Axle
    The Kodiak Disc Brake Kit - 10" Hub/Rotor - 5 on 4-1/2 - Dacromet- 3,500 lbs # K2HR35D may fit your UFP DB-42 axle. I don't have the specs on that axle to confirm, however if your spindle has an inner bearing diameter of 1.378 inches and outer bearing of 1.063 inches it will work. This comes with a seal that is 1.719 inches inside diameter and 2.565 inches outer diameter. The seal you mention does not fit perfectly, but is really close. You will need to measure your spindle with...

  • Converting Existing Hydraulic Drum Brakes on 2004 EZ Loader Boat Trailer to Disc Brakes
    Given the inside dimension you kindly provided, your outer bearing is a # L44649. We have plenty of disc brake kits that would be compatible in various finishes. Going with the Kodiak # K2HR35DS in a Dactromet/Stainless Steel finish would provide maximum corrosion resistance. The kit includes the races, but the # L68149 and # L44649 bearings and # 168255TB grease seals are sold separately. It sounds as if your current brake actuating coupler was intended for drum brakes, If that's...

  • Parts Needed to Add Brakes to a 3,000 lb Single Axle Trailer
    I recommend using an electric-over-hydraulic braking system for your 2013 Audi Q5 and boat trailer. It uses less electrical wires on the trailer which is great since it will come in contact will water fairly frequently. The parts that you will need are: Kodiak Disc Brake Kit - # K2HR35D Bearing Kit - # BK2-100 Kodiak Hydraulic Brake Line Kit - # 18SI-BLKIT HydraStar Marine EoH Actuator with Breakaway and 7-Way Harness - # HS381-9067 This is everything that you will need on your...

  • What Type of Grease Should be Used to Grease Brake Caliper Bushing
    I spoke to my contact at Kodiak and explained to him your situation and he advised that only silicone based grease be used on the bushing that the caliper slides on. He said that if you used petroleum based grease the bushing will swell and the caliper won't function right. He told me to show you the picture that I attached. If your bushings need to be replaced you would want the part # K225RB.

    For a completely stainless steel version of the Kodiak Disc Brake Kit part # K2HR35D you will want to use the Kodiak Disc Brake Kit part # K2R35S.
