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.

Over-the-Hub Rotor

Kodiak's slip-on, cast iron rotor makes it easy to convert an idler axle to a disc brake axle. Simply place the rotor over your hub. It is most often wheel bolt piloted for a loose fit and then held in place by the wheel itself. With a separate rotor and hub, you can easily repair or replace one element of your brake system without having to junk the whole thing.


Kodiak calipers are constructed of stainless steel to prevent flexing and rust. 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, corrosion-resistant dacromate-plated steel 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.

Installed this new Kodiak Disc Brake kit to replace a Tie Down Engineering set. The performance of these new brakes is phenomenal. I only have one season on them in and out of the salt water. I'm hoping that the Stainless Steel calipers will stand up over time.



The Stainless calipers and disc brake set are still functioning great after 2 years. I also installed an Electric over Hydraulic brake actuator to replace the surge brake actuator


Fast delivery and the brakes fit right.



Working great. Fits my Venture tandem axel trailer.


Fast delivery. Parts are good quality.
easy to install. Would recommend this product if you want a total brake kit.


Awesome product, very happy with the quality. As with the other package I received, could have been boxed a little better. one of the caliper brackets was starting to poke through the box and had poked into one of the internal boxes housing one of the rotors. Luckily no damage was sustained.


After one year and many trips to salt water, these are holding up about as well as you can expect them to. Way better than the cheap sets. No rust on the calipers at all. I do rinse trailer in fresh water after every trip.


Easy install on to my double axel EZ-Loader boat trailer. I replaced the factory oil bath hubs with new hubs and the brake drums/backing plate units with this disc brake kits. It all works really good! My boat & trailer sees a lot of salt water/Puget Sound. I've very happy with this set-up! Smooth stops!


Shipped the day I ordered and delivered today, within three days. Well packed. The calipers and rotors are much more substantial than another brand I am replacing them with but I have not yet installed them.


Submitted my order and it was shipped that same day. Order arrived earlier than was projected so I got my trailer together and was out on the water
Will definitely recommend you guys.



After one year the brakes work just like they are brand new The only thing I should have done was buy SS rotors.


Fast service and great products. Easy i nstall.


Products were delivered very quickly. Easy directions and installation. I just wish I would have known extra hardware would be required to install products.
Tried to talk with etrailer about the addtional bolts required but they could not offer much information. They did try to answer my questions though.
I used these guys twice and will use them again!


Working as they were designed too


Good product-WAY better than the factory brakes that came on my EZloader! Fair price. Easy to order.



product was exactly as described. Very happy


They fit, they work as promised. What more can I say, I could not be happier! etrailer is as good an online supplier as I have ever dealt with! Kudos


More than 3 weeks still not receive the items. Called many times got same answers, warehouse busy , short staffed will ship as soon as possible……no help and up have to canceled and order some where else


Quick processing, delivery and great customer communication; this is the reason I will make future etrailer purchases.


Easy assembly and good quality.



Patrick The brakes worked out very good. I am real careful to flush them with fresh water after each use. Excellent product.


Love the product. Nickolas in sales was very helpful. Would definitely purchase again.






Delivered on time and all really to go.


Great brakes

  • Replacement Rotors and Calipers for Oil Bath Hub
    As long as your hubs are in good condition, a slip-over kit like the Kodiak Disc Brake Kit # K2R35DS that you referenced will work well and be easiest to replace the rotors and calipers. You will want to ensure that the kit matches your hubs. The # K2R35DS kit has a 10 inch rotor with 5 on 4-1/2 inch wheel bolt pattern and is designed for 3,500 pound axles. I've attached the product page for all of our disc brake kits with rotors for you. If the # K2R35DS does not work for your hub, you...

  • Rotor Size of Kodiak Disc Brake Kit for 3,500 lb Axles
    The size of your current rotors are not indicative of the rotors you can replace them with. The Kodiak Disc Brake Kit # K2R35DS has 10" rotors but in order for the kit to work you only need to ensure you have a 4-bolt brake mounting flange, #84 spindles, as well as wheels that have a 5 on 4-1/2" bolt pattern and are at least 14" in diameter.

  • What Kodiak Brake Hardware is Compatible with Tie-Down Brakes on a Load Rite Trailer
    I have contacted the two manufacturers but I have been unable to confirm the compatibility of the rotors from one company with the calipers from the other. Depending on how tightly and for how long the original calipers have been frozen in their current position, it may be that your rotors have been damaged by scoring or corrosion. We always recommend that all braking system parts be replaced at the same time using rotors and calipers from the same manufacturer, which ensures both compatibility...

  • Are Brakes Pad Included in Kodiak Dacromet and Stainless Steel Disc Brake Kit K2R35DS
    The self-adjusting stainless steel calipers are included in Kodiak Disc Brake Kit # K2R35DS and do have brake pads installed on them.

  • Will the Additional Width from Slip-Over Rotors Affect the Fit of the Brake Calipers on a Trailer
    There is some additional width added when using the slip-over rotors like # K2R35DS. This is true on every application that uses this set up. The brackets and calipers are designed for this so they will line up just fine. The wheels and tires will just be 1/2 inch further out on each side. You will need to make sure that your existing axles have brake mounting flanges in order to add brakes to the trailer. If you do not have a 4-bolt mounting flange on each end of the axle, # 4-35, you...

    As long as there is a brake mounting flange on the spindle of your trailer axle there should be a way to get new disc brakes on the trailer.

    Yes, you can keep your oil bath hubs and use the Kodiak disc brakes; you mentioned a salt water environment and stainless steel brakes so you have two options, with the all-stainless steel being the best in terms of corrosion resistance, as you can see by the salt spray ratings of each: - 300- to 400-Hour Salt-Spray Rating: Dacromet and Stainless Steel: Kodiak Disc Brake Kit # K2R35DS - 1,000-Hour Salt-Spray Rating: Stainless Steel: Kodiak Disc Brake Kit # K2R35S In order to be sure...

    The Kodiak disc brake kit # K2R35DS is made up of Dacromet and stainless steel components. Dacromet has a 400 to 600 hour salt spray rating while stainless steel is about as corrosion resistant as you can get. Still when using these items in a salt water environment be sure to hose them off after use with fresh water. For the absolute best in corrosion resistance go with an all stainless kit like # K2R35S.

  • Recommended Disc Brake Kit For 20 Foot Boat Trailer
    Brake lines can get clogged, and most of the time it has to do with someone not being careful when adding fluid and getting small particles inside instead of having disintegrated parts due to corrosion. To upgrade to disc brakes, you will basically need to replace everything except the brake lines which can be blown out with compressed air. The coupler will require a stronger master cylinder for disc brakes vs. drum brakes because disc brakes require 1600 psi where drums require 1000-1200...

  • How to Determine Correct Over-the-Hub Disc Brakes for Boat Trailer
    There are a few things that you will need to know in order to choose the right disc brake kit for your 2003 DHM boat trailer. I assume you have idler hubs and are replacing your brakes so you already have a 4-bolt brake mounting flange # 4-35 as well as an actuator and brake lines. If so, the first thing you need to know to get the right brakes is the axle capacity you have, and the other is your bolt pattern.

    If the rotors are in excellent condition, are the slip on style that slip over the mounting studs it could work. But you will need to make sure they are the exact same dimensions as the ones designed to work with the kit you are interested in. But honestly, anytime you change brake pads you are supposed to either replace the rotors or have them machined. And at the price of just getting new ones in Dacromet or Silver Cadmium (which are both reasonably priced and offer good corrosion resistance)...

  • How To Find Correct Replacement Hubs for Skeeter SX2250 Trailer
    I have a few options for you to help with identifying the correct hubs on your trailer. The first and easiest method would be to crawl under the trailer and look for the axle tag on the beam. This should give an axle capacity which we can then use to find the correct hubs. The Easy Grease Trailer Idler Hub Assembly part # AKIHUB-545-35-G-EZ-K for example is for 3,500 lb axles and uses L68149 and L44649 bearings. The other option would be to take the hubs off the trailer and either read...

  • Disc Brakes Recommendation For 3500 Lb Boat Trailer
    The Kodiak disc brake kit you asked about, part # K2R35DS, will fit 3500 pound axles with wheel sizes 14 inches or larger. The 10 inch rotors have a 5 on 4-1/2 bolt pattern. The additional 1/2 inch would mean the wheels would indeed be mounted approximately 1/4 inch further out on each axle. The existing hubs along with the bearings and races would have to be removed. You mentioned that the axle has a 4 bolt flange already welded to it. I have attached a photo of how the brake mounting...

The rotors, calipers, mounting brackets and hardware in this kit are all made from stainless steel. We do also have the Kodiak Stainless Steel Idler Hub # KH84545S if you want to have that stainless as well.
