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.


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 stainless 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.

Trailer disc brake kit includes a single, rustproof hub-and-rotor assembly with stainless caliper and mounting bracket. Assembly fits 14" and larger wheels and axles with 4-bolt flanges.


I purchase a set of these disc brake conversions for a boat trailer. The instructions were almost not needed, that's how easy the kit went together. I would recommend these to anyone looking to upgrade to disc brakes. I also replaced the master cylinder.

Aloha C.


It has been a year since I installed the disc brakes. They are working awesome still. My only complaint is I didnt install them sooner.


The break flange bolts and nuts are not stainless or galvanized. They are zinc coated carbon steel which will be greatly degraded by rust if used in saltwater for just a season or 2 not to mention that you must take everything off in order to change these bolts of you find them to be less than par. Personally I think it would be better to include at least a step up to galvanized bolts and nuts especially at this price. Nonetheless it seems to be a well built product so far. Only time will tell though.

Aloha C.


I agree. I purchased stainless hardware from my local Ace Hardware when I installed my kit.


A year later and still working great, still no corrosion issues. Much better than before!

  • How to Pick Out a Disc Brake Kit for a Trailer
    The Kodiak Disc Brake Assembly # K1HR35S is a stainless steel disc brake kit designed to fit number 84 spindles. In order to determine if you have the correct size spindle on your trailer you will need to pull a hub and either measure the spindle where the bearings and seal ride or get the bearing numbers that are stamped on the bearings. If your inner bearing is a L68149 and your outer bearing is a L44649 this kit would work well for you. Or if your spindle measures 1.06 inches where...

  • Disc Brake Kit Recommendation for a Boat Trailer that Launches in Saltwater
    Since you plan to use your trailer in saltwater I would highly recommend a stainless steel kit to prevent rust. For a stainless kit for one wheel assembly you would want the # K1HR35S for example. This comes with just one brake assembly. If you have one brake axle you would need to order a quantity of two of these. If you plan to put brakes on both of your axles you would need a quantity of 4 of these. You bearings would need to be inner L68149 and outer L44649 from your current hubs and...

  • Availability of Kodiak Hub and Rotor Assembly and Spindle For Venture VRT-4500 Trailer
    I do have the Kodiak disc brake hub and rotor assemblies. If you let me know the bearing part numbers on your trailer I can get you the correct disc brake hub and rotor assembly. The Venture VRT-4500 trailer uses torsion axles, that has a conical spindle that is attached to the torsion arm. I do not have replacement spindles for a torsion axle. Usually when a spindle is damaged it ends up that replacing the whole axle is around the same price as the cost of parts and labor to just replace...

  • Tie Down, Kodiak, or Titan Disc Brake Kit Recommendation for a 3500 lb Axle Boat Trailer
    I have a great solution for you, but Tie-Down disc brake systems have a pretty poor reputation. They are known to have issues like what you described as well as rotor warping. The most common recommendation is to ditch them and go with Kodiak components as they have a stellar reputation. For a Dacromet Kodiak setup for a 3,500 lb axle the part # K2HR35D would be a great option that would work well. Ideally you would go with the stainless steel setup part # K1HR35S (would need a quantity...

  • Recommendation on a Disc Brake Kit That Will Work on 13 inch Wheels
    If you have 13 inch wheels on your trailer, then the Kodiak Disc Brake Kit # K1HR35S unfortunately, can not be used with 13 inch wheels. However, The Kodiak Disc Brake Kit, # K2HR35DS, will work on a trailer that has 13 inch wheels. You will need to make sure that your wheels has the 5 on 4-1/2 inch wheel bolt pattern. If they do not then your wheel will not fit on the brake rotors. I also linked a help article that will explain all the other parts needed to install hydraulic disc brakes.

  • Recommended Disc Brake System for Salt Water Boat Trailer with Tandem Axles
    To get the best braking power for your boat trailer you would want to have disc brakes on both axles. If you happen to be limited to one axle then you would want the rear outfitted. With a 5,000lb boat you likely have two 3,500lb torsion axles. The best finish for a salt water application is going to be stainless steel, next would be the KodaGuard and then Dacromet. For a 3,500lb 10 inch hub and rotor in stainless you will want a quantity of 2 # K1HR35S. Stainless is the best for salt...

  • Corrosion Resistance Provided by Titan Disc Brake Kit # T4843300
    The # T4843300 Titan Disc Brake System you refer to uses Titan's Dacromet corrosion-resistant plating. Performance wise, it's corrosion resistance is comparable to the silver-cadmium. Because silver-cad plating is some very nasty stuff (very toxic) it's being phased out and will be replaced with the Dacromet plating process. As far as corrosion resistance goes, the only better performer would be stainless rotors and calipers. Stainless would be a much more expensive option. We don't have...

  • Availability of Stainless Steel Disc Brake Kits for Trailer in Saltwater Applications
    We do offer stainless steel disc brake kits but these are not all-inclusive kits that include an actuator. In the 3500-lb axle rating we do have Kodiak Disc Brake Assembly # K1HR35S that uses all stainless-steel components. This kit includes one brake assembly but no actuator and no brakes lines. These items you'll need to order individually. Kit # K1HR35S fits wheels 14-inches and larger, uses the same bearings as the Titan kit (# L68149 inner and # L44649) has the same 5-on-4-1/2-inch...

  • Recommended Disc Brake Kit for a 2004 EZ-Loader with Tandem Dexter Axles
    Adding a disc brake system will be a great addition to your 2004 EZ-Loader boat trailer with tandem axles. The parts you will need for this are a disc brake kit and a hydraulic disc brake actuator. I recommend the Kodiak disc brake kit # K2HR35DS because it will have stainless steel calipers and 2 corrosion resistant dacromet plated hub and rotor assemblies. Another option for you to look at is the Kodiak disc brake assembly # K1HR35S as it includes a single stainless steel rotor, stainless...

  • Dacromet Coated and Stainless Steel Trailer Disc Brake Parts Recommendations
    For stainless steel brake parts the various components will have to be pieced together. You could go with a combination of dacromet and stainless steel parts using # K2HR35DS. With this kit the calipers are stainless and the rotors are dacromet. For stainless rotors and calipers you could use 2 of kit # K1HR35S. This kit comes with the bearings, races, and seal. Kit # K2HR35DS does not but would use 1 bearing kit # BK2-100 per wheel. For a brake line kit you can use # 18SI-BLKIT which...
