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.
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.

Excellent experience all the way around! Fast shipping. Simple installation. Great instructions and videos. Reasonable prices. The best part though is the customer service. I ended up speaking to William B a couple times and he guided me thought ordering exactly the right thing. He had me confirm various measurements on my trailer to ensure I had the correct parts. Actually he helped me discover that the parts I was removing were incorrect so if we had of replaced like for like I would have had problems. Getting this right up front made the installation and final quality what it should be. Thank you eTrailer and thank you William!

may cost a little more but I have not had any problems and Drive from Birmingham Al to Panama city beach Fl. at least 6 times a year to put my sea hunt off shore boat in to fish (Salt water) No corrosive at all yet only one flat tire
Thank you for the great service

I used this kit to add surge brakes to my 5200#-axle boat trailer. I bought it a couple months ago and it did not have brakes but really should have. The parts are well made and installed easily once I acquired the bolts I needed that weren't included. The description and pictures are not 100% clear that the mounting bolts to put the brackets on the trailer brake flange are not included. I'm not sure why they don't come with the kit but I ended up getting some 1.25" x 3/8" SS bolts to mount them. While the hat-style rotors are nice from a price and ease of replacement perspective, if your lug bolts don't have extra length, you would be better off getting the integral hub and rotor version. Finding longer lug studs for my 20 year old trailer and removing the old ones was a PITA. Had I known, I would have spent the extra $ for the integrated hub/rotor set. The calipers have bleeding screws on both top and bottom so they can be mounted on either side of the trailer. That's a nice feature as its one less thing to go wrong.
Once installed with new actuator coupler and brake lines, the brakes made a huge difference in towing the boat. The boat alone is 3000# and the trailer and gear probably add another 750 or so. It used to push my Yukon XL around when braking but now it tows smooth and easy.
etrailers was awesome to work with. Good communication via email and simple fast ordering and shipping. I will definitely use them for future trailers get needs.

Bought Kodiak full kit of rotors, calipers, and primary hydraulic actuator from eTrailer for my triple axle boat trailer and perfect result. Competitor was couple dollars cheaper, but couldn't answer simple product questions and squirrely about delivery details, and I don't have patience for that crap. Let's go eTrailer!

Great company! Everything was streamlined and processed very quickly with fast shipping. The website is among one of the best out there. Bought this Kodiak brake kit as a replacement for my boat trailer which had Tie Down parts and it fit perfect. Really helpful how to and review videos were available as well. I definitely recommend etrailer.com and am now a customer for life. Product delivered matched the description 100%.

I purchased this Kodiak Disc brake a little over a year now and had no problems so far. I check them each time I return home and they look fine. Good product.
by: Robert 10/22/2021
After one year on the trailer and a 450 mile road trip, installed parts are holding up well and foresee no problems for a couple of years.

The staff at etrailer are great. We had a urgent need to get our trailer able survey boat to project site and realized the trailer was in need of repair when we trailered the boat. I called etrailer and they had all the parts needed and was able to ship quickly to us. The parts fit and work great. Thanks a lot!

See what our Experts say about this Kodiak Trailer Brakes
- Are Kodiak Disc Brake Trailer Calipers Low Drag CalipersI checked Kodiak and the calipers of their trailer disc brake kits like the part # K2R526D are low drag calipers.
view full answer... - Recommended Idler Hubs Compatible with the Kodiak 12" Disc Brake KitThe Kodiak Disc Brake Kit part # K2R526D is compatible with pretty much any idler hub with a 6 on 5-1/2" bolt pattern therefore you won't have any issues with the CE Smith Trailer Idler Hub Assembly part # CE13711. I have attached an install video I did on the brake kit for you as well.
view full answer... - Brake Flange Mounting Bolt Recommendation for Kodiak Disk Brake Kit K2R526DThe brake flange mounting bolts are not included with the Kodiak Disc Brake Kit # K2R526D that you referenced. If you need bolts you would want the part # 7-5 for the bolt, part # 38LW for the washer and part # 38N for the nut. These aren't stainless, but they will still work fine. If you wanted to go with stainless you would have to source them at a hardware store.
view full answer... - Dimensions of the Kodiak Disc Brake Kit # K2R526DI went out into our warehouse to get all of the dimensions you requested. The inner diameter of the center hole for the rotor is 3.6 inches. The diameter of the bolt holes in the rotor are .52 of an inch. From the mounting surface of the rotor to the rotor center measures 2.25 inches. From the mounting surface of the caliper to the rotor center measures 3.15 inches. On the thicker side of the caliper the distance from the mounting flange to nearest portion of the rotor is 2.6 inches. On...
view full answer... - Which Idler Hub For Kodiak Slip On Disc Brake Kit With 10" Rotors and 5 Lug Bolt PatternSince your customers boat trailer has 10" single piece rotors currently on it that tells me that they have a 3500lb axle and that you ordered the Kodiak Disc Brake Kit - 10" Rotor - 5 on 4-1/2 - Dacromet - 3,500 lbs # K2R35D. For a compatible idler hub to work with this two piece rotor kit you will want to go with the Kodiak Trailer Hub for 3,500-lb Axles - 5 on 4-1/2 - Galvanized Steel # Q-HUB84545 which has the 5 on 4-1/2" bolt pattern you were looking for and is designed specifically...
view full answer... - Determining Bolt Pattern for Kodiak Disc Brake Kit # K2R526DThe 5-1/2 bolt pattern is part of the 6 on 5-1/2 mounting pattern that the Kodiak Disc Brake Kit # K2R526D mounts on, this will be the same as your wheel's bolt pattern. To determine what mounting pattern you have I have a Help Article for you to look at, that I've attached. Basically you need to determine if you have a even or odd number of lugs/posts on your hub. If you have 6 then that's even, since it's even you will want to measure from center to center of the lug directly across...

- Disc brake Kit For EZ Loader Trailer With 5,300 lb Torsion AxlesThe Kodiak disc brake kit # K2R526D will fit your 2018 EZ loader trailer with a 5,300 lb axle. It uses a 5 bolt brake flange which is standard for axles 5.2K-7K. The slip on rotors will work with virtually any 6 on 5-1/2" idler hub. We generally recommend a hub like the # 8-213-5UC1-EZ to go with it. Your UFP hubs should be very similar to the Dexter brand.
view full answer... - Disc Brake Kit for Converting Trailer with 84 Spindles to Electric Over Hydraulic DiscThe Kodiak Disc Brake Kit # K2R526D wouldn't be ideal for you since you have an 84 spindle as this kit fits idler hubs that fit the 42 spindle. A better option would be the Kodiak kit part # K2HR35D which comes with hub/rotors that fit the 84 spindle. Then for an actuator kit that comes with everything needed plus an actuator with the best reaction time and reliability you'd want the Hydrastar part # HS381-9065.
view full answer... - What Is Dimension Between Bolts On The Caliper On The Kodiak Disc Brake Kit, # K2R526DOn the Kodiak Disc Brake Kit, # K2R526D, the distance between the center of one bolt to the center of the other bolt on the caliper is 5-3/4 inches. You would need to measure the distance of the bolts on your 2003 Mastercraft Trailer to know if this caliper will fit on your trailer. This caliper is made to work with the mounting brackets in the Kodiak Disc Brake Kit, # K2R526D. The Kodiak Disc Brake Kit, # K2R526D, is for 5,200 lbs. to 6,000 lbs. trailers with 15 inch and larger wheels...
view full answer... - Troubleshooting Bleeding Kodiak Disc Brake AssembliesI'm glad to hear you have tested the HydraStar Marine Electric Over Hydraulic Actuator w/ Breakaway and 7-Way RV Harness - 1,600 psi # HS381-9067 and found it to be working properly. The Kodiak disc brake calipers like kit # K2R526D have a two piece bleeder valve so if you only adjust the bottom section to attempt bleeding, that is the cause of your frustration. I've attached a couple photos to assist.

- Can Dico Model 10 Surge Coupler be Used with Kodiak Disc BrakesIf your Dico Model 10 surge coupler is designed for use with disc brakes then yes, it will work with Kodiak disc brakes # K2R526D. If your model 10 is designed for drum brakes then you can replace the master cylinder with # T4747100.
view full answer... - Will Dexter 5.2K Idler Hub Fit with Kodiak 12" Disc Brake KitYes, the Dexter Trailer Idler Hub Assembly # 8-213-5UC1-EZ is compatible with the Kodiak Disc Brake Kit # K2R526D. I actually don't think that the placement of your wheel/tire will be that much different than when you are using hub and drum assemblies. I went out to the warehouse and found that the idler hub measures 2.095" from the back of the hub to where the rotor will sit and the rotor is 0.3065" thick meaning that your wheel will mount about 2.4015" from where the back of the hub (or...
view full answer... - Are 4 Bolt and 5 Bolt Trailer Brake Flanges Cross-Compatible for Disc BrakesThe 4 bolt brake mounting flanges are used on axles up to 3,500 lbs. If the axle is any larger then it will likely use a 5 bolt flange. There is one exception to this which is select 4,400 lb axles. That said, you cannot use 4 bolt brakes with 5 bolt flanges or vice versa. In order to choose the correct disc brake kit you'll need to know the axle capacity. The Kodiak Disc Brake Kit part # K2R526D for example is for 5,200 lb axles. I have attached a full list of options below.
view full answer... - Adding Hydraulic Disc Brakes And Surge Coupler To Trailer With No BrakesSince you want to install a surge disc brake system on the trailer you will not need a brake controller on your vehicle or a 7-way trailer connector. I have attached a helpful article that explains how to add brakes to your trailer you can check out. You will want to make sure the trailer has a brake mounting flange installed on the axle. If it does not then it will need to be installed by a qualified professional. Once you determine what size brakes are needed on your trailer you can...
view full answer... - Do Dexter and Kodiak Disc Brake Kits Use Same Mounting BracketsThe mounting brackets of the Kodiak kit like the # K2R526D and the Dexter kit part # K71-647-648 locate the caliper relative to the hub in a slightly different position as well as use different bolt hole dimensions. Because of this the two kits aren't compatible with each other. The Dexter is much more offset towards the axle than the Kodiak, but that doesn't necessarily mean one is better than the other. Both of these brands do things differently but have a great reputation as being very...
view full answer... - Are There Replacement Brake Pads for the Tie Down Engineering (TDE) 46304 Disc Brake CalipersI do have an option for you but we don't offer any replacement brake pads for the Tie Down Engineering (TDE) 46304 Caliper as the company is no longer in business. Therefore, our only option to you would be a full replacement for which I recommend the Kodiak Disc Brake Kit part # K2R35D if you have a 3,500 lb axle or the Kodiak Disc Brake Kit part # K2R526D is you have a 5,200 lb or 6,000 lb axle.
view full answer... - Recommended Disc Brake Kit For 5,200 Lb AxleWe do offer several disc brake kits for 5,200 lb axles. One of the disc brake kits I recommend is part # K2R526D. This is designed for axles up to 5,200-lb to 6,000-lb and has a 12 inch rotor with a 6 on 5-1/2 bolt pattern. This kit includes the rotors, calipers, mounting brackets and mounting bolts. This is designed for a 5 bolt brake mounting flange. I have attached a link to our product page for the kits we offer. I have also attached a couple links to helpful articles about disc...
view full answer... - Will Kodiak Disc Brake Kit # K2R526D Fit Torsion AxleYes, the Kodiak disc brake kit part # K2R526D can be used on a torsion axle with a capacity between 5,200 and 6,000 lbs.
view full answer... - Can Idler Hub and Over-The-Hub Rotors Be Used to Convert to Hydraulic Brakes on CamperYou can certainly use idler hubs with slip on rotors to convert your 5th wheel camper to hydraulic disc brakes from electric drum brakes. As you noted, the benefit of this is being able to replace the rotors more easily down the road. This is nice if you find yourself in a situation where only either the hub or the rotor has been damaged, and only one of the two components need to be replaced. The Kodiak Disc Brake Kit # K2R526D that you referenced is a great choice for your camper. These...
view full answer... - Will Kodiak Disc Brake Kit Replace UFP Brakes On 5,200 Lb Torsion AxleThe correct Kodiak Disc Brake Kit for a 5,200 lb axle is part # K2R526S for stainless or part # K2R526D for dacroment. In regards to compatibility, the brake mounting flange and spindle size are the only factors we can confirm. I don't foresee any issues but test fitting would be the only way to confirm. There are no exclusions for torsion axle trailers in general.
view full answer... - Best Disc Brake Setup For A Tandem Axle Trailer With 10,000 Lb. CapacityIn order to determine the correct disc brake setup to use on a 5 ton trailer, I would need to know the capacity of your trailer's axles. You can find this by locating the information tag placed on the center of the axle or by calling the dealer with your VIN. I have listed my disc brake recommendation for the following axle capacities: 3,500 lbs : 2 Kodiak Disc Brake Kit part # K2HR35D 5,200 lbs : 2 Kodiak Disc Brake Kit part # K2R526D 7,000 lbs : 2 Kodiak Disc Brake Kit part # K2HR712D Remember,...
view full answer... - Dimension From Center of Rotor to Outer Edge of Caliper on Kodiak Disc Brake Kit # K2R526DOn the Kodiak Disc Brake Kit, part # K2R526D, the measurement from the center of the 12-inch rotor to the top of the caliper is about 6-3/4 inches. I am including a picture that will show that measurement. The overall diameter of the rotor is 12.16 inches and the caliper sits about 3/4-inch above the edge of the rotor.
view full answer... - How To Transition A 2021 Grand Design Reflection 278BH To Electric Over Hydraulic Disc Brakes To switch over to electric over hydraulic disc brakes you'll need start by finding the bearing and grease seal combination for your trailer's axles so that we can find a compatible hub/rotor assembly. If you remove the hub and measure the spindle with a set of calipers # PTW80157 at points B, C, and D from the diagram below we can use these inner diameter measurements to determine a fit. From there we'll need to determine the correct length brake line kit to make the run from the front...
view full answer... - How to Prevent Rust on Disc Brake RotorThe best thing you can do to help prevent rust on your # K2R526D rotor surface is to clean them before storing the trailer. It is likely you will still get a little surface rust which is a common occurrence and not something to be overly worried about. Once you drive the trailer and hit the brakes a few times the rust will be gone. The only way to completely prevent this would be to upgrade to stainless steel rotors like # KR12S
