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.


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.

Video Transcript for Kodiak Disc Brake Kit Installation

Speaker 1: Today we'll be having a look at the Kodiak line of disc brake kits. Here's what our brakes look like installed. Now the reason you're gonna want these particular brakes over your traditional electric style drum brakes is that having hydraulic disc brakes will give you a much better stopping performance and ability than what you would have with the drum brakes. You'll be able to stop a lot faster, a lot smoother, and a lot safer.We're putting less work on our truck and more work is being performed by out camper, our trailer, or our fifth wheel, whatever we are putting these brakes on. Now one of the reasons that we're going to have enhanced stopping ability is because we have a large diameter rotor which gives us increased surface area for our brake pads to bite onto. By having the large rotor this also helps dissipate heat better.

We also have a vented rotor which will help dissipate the heat better. By having the heat being dissipated we are going to have increased brake life and power as we're stopping because as our brakes get hot they get less effective and you experience what is know as brake fade, the hotter the temperature of the brakes the less effective they are at working properly.Now our pads are applied to our brake rotor by our caliper. We have a single piston here which pushes our inner brake pad against the inside surface of the rotor and pulls the caliper towards the rotor so the outside pad makes contact and our caliper has two slides, one at the top, one on the bottom. As the piston pushes the inner pad against the rotor it pulls the caliper body itself with the outer pad onto the rotor thus clamping it, squeezing our rotor, and slowing it down, bringing our trailer to a stop. This piston is designed to operate off hydraulic pressure of at least 1,500 PSI, just keep that in mind if you're converting an old trailer that has electric drum brakes, you need to purchase an actuator that puts out at least 1,500 PSI.Now just like automotive grade brake pads these brake pads are equipped with a chamfered edge on the end and that chamfered edge will help prevent us having squealing and squeaky noise as the brakes are being applies, it'll also help reduce chattering.

This will give us a smoother and quieter ride.The brake pads themselves are made of a ceramic construction which will help cut down on brake dust and also give us more resistance to heat as we're stopping. Now our caliper, our bracket, and our rotor are available in different finishes, we can get them in an E-coat finishing like this, a dacromet finish, or a raw finish it just depends on what you're looking for. The dacromet and the E-coat will be more resistant to rust and corrosion over the course of time over the raw finish.Now these brakes are a great solution for 7,000 pound axles such as this one. They have an eight by six and a half inch bolt pattern and they are available with half inch or 9-16th inch diameter studs depending on your application.Now what I really like about these brake kits compared to other options out on the market is that by having ourselves a disc brake system we get the comfort and stopping ability that we're used to by driving our normal truck or our street car versus having the drum brakes that we use to have. These give us the stopping ability and the comfort that we're used to seeing in a typical automotive vehicle because it's the same concept, it's a hydraulic disc brake versus an electric drum brake.Now only do these stop better than electric drum brakes but we're also going to see a lower service cost when it comes time to actually needing to service our brakes again.

Unlike drum brakes where it's a little bit time consuming in order to replace your shoes in order to replace the brake pads on the system it's a simple matter of just removing two bolts, the caliper slides off, and you can put new pads in, put it back in. It's gonna cost you less money and less time in order to get back on the road.Here's what our kits comes with, we have two of everything you see pictured here. We'll have two rotor hub assemblies, two caliper mounting brackets, two calipers, and two sets of caliper mounting bolts. This is everything that you'll need to put brakes on one axle of your trailer.To begin our install we need to remove our old hub assembly. In this particular case we have electric drum brakes that we're installed so this will be a great upgrade once we replace these.

We'll need to remove our dust cap here, what I like to do is take a flathead screwdriver, go behind the lip, and we'll start to tap it out with a hammer. Now we want to make sure we clean out as much of the old grease from our dust cap as possible. Now we'll clear away the grease from our spindle. Okay with that cleared away we can find our nut retainer from behind all the grease, you'll have a couple different ways of having your spindle nut held in place, ours we have a retainer clip, you could have a cotter pin on yours.For this one we'll use a flathead screwdriver, come behind it, and it comes off. With this removed we can now spin off our nut. We'll set these aside because we will need them later. We'll now remove our washer, just use our flathead screwdriver to help pull it off the spindle. With our washer removed we can now remove our hub assembly. In order to do that just pull it towards you and we can set it aside. Now we'll wipe off all the grease from our spindle and inspect it for any damage such as burring, hot spots, nicks, or wear patterns.Now since our particular axle is an easy lube axle by having the zerk fitting here we're going to flush out all of the old grease from inside of it by using our grease gun. We'll stick it onto the fitting and we'll pump it full of grease until we get clean grease coming out of the spindle. You can see how we flushed out the old grease that way we have fresh, new grease coming out of the port from the spindle, wipe that off, this way we know we don't have any contaminants inside of our axle.Now since we have electric brakes on this trailer we need to remove the wires that go to our magnet. Let's cut those off and make sure we leave slack in case we ever decide to go back to electric brakes that way we can still hook them up and use our existing wiring. Now we can unbolt our backing plate assembly, in order to do that there are five nuts that go around the spindle that hold it in place. Now we can grab the backing plate assembly, pull it off, and discard it. Now that we have our backing plate off and we have most of our brake dust removed we can now really clean off our spindle and get it ready for the install. We'll use some brake parts cleaner, hose it down really good, and wipe it clean.Now we can take our caliper bracket, you'll notice how there's multiple holes around it, this is so we can gain our proper orientation on our axle. These brackets are not side specific, you can put it on either side of your axle, it doesn't matter. The only thing you want to make sure is that this part that says outside faces outside and your caliper attachment points face as close to the back of the axle as possible. We'll slide it on and match up our holes appropriately, as you can see here where we have it it's almost level and it faces towards the back so this is ideal for us. We'll now reinstall the nuts that we're removed, we'll tighten these down, I like to tighten them like a lug nut on a wheel in a crisscross pattern. Now we'll torque them to the appropriate amount.Now to carry on with the installation of our brakes we're ready to grease our wheel bearings and get them installed. Now we have the option of reusing our old ones but since we're putting a whole brand new hub assembly with a rotor on we're going to use new bearings. In our case we're using part number BK3-200. It even comes with new races but since we have brand new races installed on our hub already we're not gonna need the races nor are we gonna need the cotter pin that comes with the kit because we have a clip method of securing our spindle nut.Now we'll take our inner bearing and we'll start to grease it up just by sticking inside a tub of grease and we'll work this grease into our rollers by spinning it as we push it in. You can see we start having the grease come through and covering up our rollers all the way through and it's nice and fluid with no breaks in the grease, that's when we know we're starting to get grease adequately packed inside of our bearings. Wipe some here on the outside edge, we even have it coming through on the other side. Get a nice coating going around the outside of it, we'll wipe some around the inside where it rides against our spindle. Once we have it in the hub we'll rotate it a few times to make sure it spins nice and freely.Now we will install our seal, place it inside, make sure it's sitting as flush as possible, and we can drive it in. Now if you don't have a seal driver what you can use is a block of wood, place it square over the seal, and we can tap it in with a hammer. Once it's sitting flush around the edge of our hub we know we have it properly installed. Now that we have our inner bearing and seal installed we can take some brake parts cleaner, spray it on a towel, and we'll wipe off any oil or grease residue that's on the backside of our rotor assembly.Now we can take our hub assembly and we'll slide it on to the spindle of our axle. Now we can grease our outer bearing the same way we did the inner bearing. Now we can install the outer bearing, we'll slide it into our hub assembly, making sure it goes in properly. Now we'll take our washer, line the notch up with the notch in the axle, push it on, take our nut, thread it onto the spindle. Now we'll start to tighten our nut down, we don't need to have this super tight, just enough that it starts to take all the play out from side to side movement and it is secure. Once it starts to get tight you'll probably have to rotate the hub as we tighten it. We may need to back it off a little bit. Now we will install our nut clip that we removed earlier, that'll keep our nut from backing off.Now we'll take our grease gun, go over the zerk fitting on our axle and we'll pump it full of grease. Now that we see grease coming out of our outer bearing completely we know that the hub and bearings and spindle are completely saturated with grease which is exactly what we're looking for. Now we can reinstall our dust cap, okay with our dust cap back on we'll rotate our hub and rotor assembly and make sure there's no abnormal noises and that it's rotating smoothly and we'll check for any play in it. If we don't feel anything that means everything's good and we can carry on with the rest of the installation.Now we'll take some brake parts cleaner and we'll clean the rotor surface on the outside like we did on the backside. Now we can take our caliper, we already have our two bolts and our slides and we'll install it onto our bracket. We'll screw the bolts into our bracket, we'll tighten the bolts down with a wrench, there are 13 millimeter heads on them. On the backside of our caliper right in the center we'll find the port where our brake line screws into. We'll remove the red plastic plug from the fitting just by unscrewing it, take our brake hose, place it inside the fitting, thread it in a few turns by hand first, and then we'll use a line wrench to tighten it down. You use a line wrench on brake line fittings or brakes hoses because it won't strip off the end of the nut and you'll be able to get a good grip on it to sufficiently tighten it down. We don't need to over tighten these, just enough so it's tight and won't leak. Now that we have this all installed we'll repeat the same process for the other side of the axle.Now we need to begin the process of bleeding our brakes. When we bleed the brakes we'll make sure we're using the top bleeder screw, not the one on the bottom, and we'll be using the smaller section here which is a 5-16ths nut. We'll use a line wrench on this so we don't strip it and we'll have an assistant apply the brake controller on our towing vehicle or pull the brake away switch for our braking system. Go ahead open the bleeder and we're looking for a solid stream of fluid with no air bubbles. Once we have no air bubbles we'll close the bleeder and release the brake away switch and we'll move on to the next one.That completes our look at the Kodiak line of disc brake kits.

I have a 2015 GMC Sierra 2500HD Diesel, towing a 2017 Pinnacle 36FBTS 5th. wheel. The Pinnacle has a standard drum braking system. On a long trip this year I cracked both rotors on my truck from over heating related to the Pinnacle's drum brakes failing to fully provide proper stopping. I decided no more, and after much review I replaced the factory drum brakes with the Kodiak Discbrake system. (my first time ever doing something like this) In addition, one of the key items for me was a way not to replace my on-board factory trailer brake controller, (did not want to use an aftermarket product, that would diminish the interior look ) thus I also added the control Adapter Module that enabled me to use the factory installed brake controller. With all this change I decided to also go ahead and add a separate brake away battery. Everything I just described are shown in the attached photos. I found eTrailer extremely helpful in answering questions, although I did not have a lot of questions since their online videos proved most helpful. All parts of the Kodiak system worked fantastic following a 2500 mile trip. The improved braking is superior, and I did not need to replace my on board controller, but continued to use it by installing the control adapter. The disc brake picture is one of the disc brakes that I examined following our trip...all in perfect shape with everything working great for the entire trip. 611000

The brake system has certainly exceeded expectations and is clearly one of the best RV upgrades I've made. Stopping distance is greatly improved. Installation is a breeze for even semi-mechanically inclined. The only small bit of an issue was one of the four caliper brackets I received was different than the others, but as it turned out either of the styles worked. I'd definitely add the wet hub option which adds bearings and a different inboard grease seal to the shopping list. It's worth the extra few dollars. 459947

One year ago I decided to switch to Kodiac Disc Brakes. It was a great decision. I installed them on my 16 k Escalade fifthwheel. I installed all new wheel bearings and oil bath hubs. Although The oil caps leaked slightly and Kodiac sent new ones I still had the issue. I resolved it by using the Dexter oil caps. I believe the o rings were the issue. I have been a customer of Etrailer for about seven years and they have always been very helpful and provided five star service. My fifthwheel stops a lot quicker than the brake shoes did. If you are thinking about it don't wait any longer order yours now and you will not be disappointed. Good job everyone at Etrailer. 278350

Kodiak brakes are very well made and the fit is perfect. Etrailer is so easy to work with. I ordered the wrong brake the first time, but Cathy H. arranged the return and got the right part on the way. I wish every business provided such a pleasant experience. 207562

  • Picking Out Trailer Hub/Rotors for Dexter 7,000 lb Axle
    I really wish I had a way to look that up but since either hub would fit the same spindle that info isn't available for me to look up. You'll have to measure the stud diameters and go with the part # K2HR79E if they are 9/16 inch or part # K2HR712D if they are 1/2 inch.

  • Recommended Disc Brake Upgrade Kit for 2014 Heartland Big Horn 3010RE 5th Wheel Trailer
    The Kodiak Disc Brake Kit - 13" Hub/Rotor - 8 on 6-1/2 - E-Coat - 7,000 lbs # K2HR79E or the Kodiak Disc Brake Kit - 13" Hub/Rotor - 8 on 6-1/2 - Raw Finish - 7,000 lbs # K2HR79 will work with the #42 spindles that are on 6K Dexter axles.

  • Replacement 7k Disc Brakes for Kaufman Trailer
    The 7,000 pound Kodiak disc brakes, part # K2HR79E, will fit your spindles but we've actually learned from Kodiak that their 7k disc brakes have issues with Kaufman trailers because of the wheels that Kaufman uses. Apparently, those wheels are made so that the center plate that has the mounting holes is welded on the inside of the wheel instead of the outside and it interferes with Kodiak's calipers. Technically, the brakes work on the trailer but you'll need different wheels. Another...

  • Will the Kodiak Disc Brake Kit # K2HR79E Work with the Dexter EZ Lube 7000 Pound Torflex Axles
    I spoke with my contact at Kodiak and he said that the Disc Brake Kit, # K2HR79E, will work with your Dexter EZ Lube 7000 pound Torflex axles. In addition to the brake kit, you will need the following: Inner Trailer Hub Bearing, # 25580, Qty 2 Outer Trailer Hub Bearing, # 02475, Qty 2 Grease Seal, # RG06-070, Qty 1 These will work with wheels that have an 8 on 6-1/2 bolt pattern and 9/16 inch wheel stud diameter.

  • Kodiak Trailer Disc Brakes for 7,000 lbs AL-KO Axles
    Yes, it is safe to assume that a 7K axle from AL-KO built in 2014 will have standard spindle and brake mounting specs. It looks like you were looking at disc brakes. If that is the case, the Kodiak Disc Brake Kit, # K2HR79E, that you came from will fit your axles. The bearings and seals are sold separately, so I listed them for you below Inner bearing - # 25580 Outer bearing - # 02475 Grease seal - # RG06-070 or Oil seal - # 10-63 You will need two of each part number.

    Replacement bearings can best be selected by using the part numbers on the current parts; the linked image show you the typical location and appearance of the part numbers on bearings, races and seals.

  • Switching to Electric Over Hydraulic Disc Brakes on a 2015 Landmark Key Largo 5th Wheel Trailer
    We do have the kit you are looking for, # K2HRCM1337-9DAC. In addition to the brakes themselves you will need the electric over hydraulic actuator that you mentioned, # HBA16, for disc brakes. Since you have the integrated brake controller on your 2008 GMC/Chevy Sierra/Silverado 3500 you will need the adapter, # HBA-CAM. The only other part you will need is a breakaway kit if you do not already have one, # 50-85-313. That takes care of the brakes and electrical/actuator parts. For...

  • Difference Between Oil Bath Hub and Grease Hubs
    Yes, oil hubs and grease hubs use the same cavity to oil and grease, through the center cap. The main difference is a standard grease hub for an EZ lube spindle is grease is pressed into place and maintained through the center cap and an oil bath hub cap, has a rubber seal, holds oil and screws into the hub. The Kodiak Disc Brake kit part # K2HR79E is an oil bath hub so the center cap of the hub fills with oil. The oil in the center cap oils the spindle while you going down the road....

  • Parts Needed to Convert Tandem Trailer from Electric Drum to EOH Disc Brake Operation
    We can help you with planning the conversion of your trailer's electric drum brakes to electric-over-hydraulic (EOH) disc brake operation. A complete recap of the items needed is included in the linked article. I also linked our main page for 7K hub-and-rotor disc brake kits from Kodiak and Titan. All are usable with 16-inch or larger trailer wheels and all have the 8-on-6-1/2-inch wheel bolt pattern. For a kit with 9/16-inch wheel studs you could use Kodiak kit # K2HR79E. I also linked...

  • Will 7k Kodiak Disc Brake Kit with 9/16 inch Studs Fit Same Spindle as Kit with 1/2 inch Studs
    As far as your spindle is concerned all that matters is that the inner diameter of the bearing is the same, which it is between the bearing numbers # 14125A and # 02475 so the 9/16 inch stud kits you mentioned for the Lippert 7k axles would work well. The Kodiak kit part # K2HR79E would fit your spindle and work well. It has the stud size you want also. I also attached a link to a page that has a guide for converting trailer brakes from drum to disc for you to check out as well.

  • Do Caliper Pins Need to be Lubricated When Installing Disc Brakes on a Trailer
    The caliper pins do not need lubrication on a trailer. I've attached a video and an article on installing disc brakes for you to take a look at. Although it wouldn't hurt anything if they are lubricated either.

  • Axle Ratings and Parts Needed to Convert to Disc Brakes for Trailer with Tandem 7,000 Pound Axles
    As long as there is nothing wrong with your current axles there is no need to replace them. If your concern is because combined their capacity only equals 14,000 pounds that's not a problem because you have to keep in mind that part of the trailer's weight will be on the hitch. One of our most popular disc brake kits is the Kodiak # K2HR79E. It's for 7,000 pound axles, like yours and has a 8 on 6-1/2 bolt pattern. For the brake lines you can use # HS496-252.
