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.

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%. 865045

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! 405297

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. 281315

Ask the Experts about this Kodiak Trailer Brakes

  • Differences Between Combined Hub & Rotor and Separate Hub & Rotor Brakes
    The only real difference between using an integrated hub/rotor combo and a separate hub and rotor combo is that if something happens to the rotor and or hub on the separate hub/rotor, you can just replace the damaged component and not the entire assembly. As long as the idler hub you have on your trailer now has a 6 on 5-1/2" bolt pattern, then I recommend using the Kodiak Disc Brake Kit part # K2R526D. If you already have the calipers and mounting brackets then you can use part # KR12D...

  • Will Dexter 5.2K Idler Hub Fit with Kodiak 12" Disc Brake Kit
    Yes, 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...

  • Dimension From Center of Rotor to Outer Edge of Caliper on Kodiak Disc Brake Kit # K2R526D
    On 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.

  • Determining Bolt Pattern for Kodiak Disc Brake Kit # K2R526D
    The 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...

  • What Is Dimension Between Bolts On The Caliper On The Kodiak Disc Brake Kit, # K2R526D
    On 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...

  • Brake Flange Mounting Bolt Recommendation for Kodiak Disk Brake Kit K2R526D
    The 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.

  • Can Idler Hub and Over-The-Hub Rotors Be Used to Convert to Hydraulic Brakes on Camper
    You 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....

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....

  • Troubleshooting Bleeding Kodiak Disc Brake Assemblies
    I'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.

  • Inexpensive Corrosion Resistant Disc Trailer Brakes for Salt Water Use and a Boat Trailer
    The best possible material for saltwater applications is going to be stainless steel but since cost is a factor stainless would not be the way you would want to go. The next best thing is going to be a brake kit with Dacromet finish like # K2R526D. The Dacromet has a 400 to 600 salt spray rating but it is always a good idea to spray them of with fresh water after use in salt water. This kit is designed to fit over idler hubs with a 6 on 5-1/2 bolt pattern and 15 inch or larger wheels...

  • Electric Over Hydraulic Disc Brake Setup Recommendation for a Tandem Axle Trailer
    If you do have 6 on 5-1/2 inch bolt pattern wheels you would want to start with two sets of the Kodiak Disc Brake Kit # K2R526D. These will work on your 5 bolt mounting flange, have enough capacity as they are for 5,200 and 6,000 lb axles. I would strongly recommend you determine your bolt pattern before you buy anything though. Check out the FAQ article I attached on determining bolt patterns.

  • Replacement Brake Calipers for EZ Loader TIAB 27-31
    I contacted EZ Loader and got some information on your trailers. They could narrow down that you have 12 inch rotors, but they could be from two different manufacturers, Kodiak or UFP. If you have Kodiak rotors, then Kodiak Disc Brake Caliper - Dacromet - 3,500 lbs to 6,000 lbs, # KDBC225DAC, are the right replacement calipers.

  • Do Dexter and Kodiak Disc Brake Kits Use Same Mounting Brackets
    The 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...
