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 that will require repair or replacement, thus reducing maintenance costs.

Rotors and Hub Spacers

Kodiak's slip-on, cast iron rotors work in conjunction with the included hub spacers to easily convert your idler axle to a disc brake axle. The hub spacers are designed to replace your standard idler hubs, and they come furnished with races and wheel bolts (bearings and seals are sold separately). Once the spacers are in place, the rotors can be slipped on. With a separate rotor and hub, you can easily repair or replace just one element of your brake system without having to junk the whole thing.


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 4-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.

  • Do Disc Brake Hubs Stick Out Further than Drum Brake Hubs
    All of our trailer wheels have a zero offset which means that the mounting flange for the wheel is centered in the wheel. This means that the wheel would stick out about half the width of the wheel/tire past the hub/drums of the trailer. If instead you were asking about the wheel location relative to going from drum to disc brakes like with the kit # K2HR2D the wheel would end up in the same location.

  • Can the Calipers of the Kodiak Disc Brake Kit K2HR2D Mount in 12:00 Position
    Mounting the calipers of the Kodiak brake kit part # K2HR2D in the 12:00 position will still work. Since the bleeders would still be on top of the setup the air will still bleed out of them. Basically the calipers can install in nearly all positions but in the standard positions bleeding is a bit easier since air wants to float up.

  • What is the Depth of the Hubs in Kodiak Disc Brake Kit K2HR2D
    On the Kodiak disc brake kit for 2,000 pound axles # K2HR2D it measures 3.45 inches from the hub face to the brake mounting flange. Compare that to the hubs you have now to determine if the disc brakes will make the wheels further from the trailer. I have included a picture as well showing some other dimensions.

  • Will the Kodiak Disc Brake Kit # K2HR2D Fit an EZ Loader Trailer with 2,500 lb Axles 12 Inch Wheels
    There are a few additional factors to consider other than the wheel size before determining if the Kodiak Disc Brake Kit, # K2HR2D, will fit on your trailer. According to Kodiak, this kit was designed to fit 10 inch to 13 inch wheels, so they will work with 12 inch wheels as long as the wheels have a 5 on 4-1/2 inch bolt pattern. I have attached a help article on how to determine your bolt pattern if you do not know your bolt pattern. The best way to make sure this brake kit will be compatible...

  • Does Brake Caliper Mounting Flange Need to be Modified to Install Kodiak Disc Brake Kit # K2HR2D
    If you install the Kodiak Disc Brake Kit # K2HR2D with the included bolt on mounting flange you would not have to worry about the piston not fitting with the bracket. I attached a picture that shows the backside of the caliper and you can see that the piston does not stick out past the bracket mounting surface.

  • How To Confirm Fit of Kodiak Disc Brake Kit
    The Kodiak Disc Brake Kit part # K2HR2D is designed for 2,000 lb axles which use L44649 bearings. Therefore, so long as these are the bearings your axle uses, you have a four bolt mounting flange, and wheels between 10-13" then it will fit.

    You can refer to the linked article on adding hydraulic disc brakes to a trailer for a complete recap of the items needed and the things to consider about the available options.

  • What Bearings Are Used in the Kodiak Disc Brake Kits for 2000-lbs and 3500-lbs Axles
    I have information that you might find helpful, but we do not have a schematic drawing of these parts available. With that said, if you've got a spindle from a Hyundai Elantra on this buggy then you're most likely only going to be able use parts that also fit on a Hyundai Elantra- which trailer parts most likely will not. However, I can tell you that the Kodiak # K2HR2D uses # L44649 bearings for the inner and outer bearing, so they're designed for a straight spindle with a 1.063" diameter,...

  • Troubleshooting Weak Trailer Brakes on 2015 Jayco X20E
    Before you swap out the brakes have you tried manually tightening the assemblies to get them to grab harder? On electric drum brakes there is a star wheel at the bottoms of the assemblies that you can turn using a flat head screw driver or brake adjusting tool # W80630. Turning the wheel one way will bring the shoes closer in and turning it the other way pushes the shoes out more. You will adjust the brakes using that wheel until there is a slight but constant drag of the shoe pads on...

  • Can the Kodiak Disc Brake Kit Part # K2HR2D Be Used with 16 Wheels
    I do have an option for you but the Kodiak Disc Brake Kit part # K2HR2D only works with 10"-13" wheels as the hub/rotor combinations is not large enough for use with 16" wheels. The wheels would physically fit on the hub assuming you have a 5 on 4-1/2" bolt pattern but would not be rated for the wheel size. You would also need to confirm that your trailer's spindle uses L44649 bearings for both the inner and outer seat. Your best option would be to change wheel size from a 16" diameter...

    The Kodiak Disc Brake Kit - 8" Rotor/Hub part # K2HR2D is designed for a trailer with 2,000 lb axles which uses L44649 bearings. In order to confirm fit you'll need to identify the axle capacity which is usually listed on the axle tag in the center of the beam. If it's not listed here then you'll will need to pull apart the bearings and or measure the spindle. I have attached a help article below to assist with this.

  • Disc Brake Kit for Trailer with 2,200 Pound Axle and 14 Inch Wheels
    The hub spacers on the Kodiak Disc Brake Kit # K2HR2D referenced in your question simply provide an attachment point for the rotors. They should not cause the wheels to stick out further on your trailer but to be sure you can also take a quick measurement on your existing idler hubs. On these hubs there is a 3.45 inch distance from the hub face to the brake mounting flange. You can compare this to your current hubs to see if there will be any difference.

    In order to choose the correct disc brakes for a 2010 Sea Doo Challenger 180 Trailer you'll need to know the axle capacity. If you have a 2,000-2,200 lb axle you can use the Kodiak Disc Brake Kit part # K2HR2D but if you have a 3,500 lb axle then you can use the Kodiak Disc Brake Kit part # K2HR35D.

  • Difference Between Kodiak Disc Brake Kits
    There are major differences between the brake kits you mentioned, with the most important being fit and braking power.

  • Hydraulic Disc or Drum Trailer Brakes for 10 Inch Wheels
    We have several options for trailer brakes that will fit a 10 inch wheel. For a 10 inch wheel you will need a 8-1/2 inch hub and drum assembly such as # T1544500042 which has a 5 on 4-1/2 bolt pattern. Then for hydraulic drum brakes we have just one option, # T4442000 for the right side and # T4442100 for the left side. These are designed for 3,000 pound axles. For disc brakes we have the following options: For 2,000 pound axles we have # K2HR2D. For 3,500 pound axles we have # K2HR35D-8.

    The disc brake kit you referenced, Kodiak Disc Brake Kit # K2HR2D, fits 2000-lb axles and is compatible with 13-inch wheels. To ensure these hub/rotor assemblies will fit your spindles you'll need to verify the bearing numbers in your current hubs and choose a disc brake kit that uses the same bearings. You also need to verify your axle capacity to select a kit that will offer enough stopping power. The brake caliper mounts in this kit will be compatible with your existing 4-bolt brake...

  • How to Determine Fit of Disc Brakes for Trailer With 2,000 lb Axle and 7 Inch Drum Brakes
    We do have a potential option for you, and since you mentioned your current drum brakes are 7 inches, that means very likely have a 2,000 lb axle. There isn't a specific fit we have for a 2002 Load Rite, so what you will need to do is some measuring in order to ensure the right fit. The most likely kit that will work is the Kodiak Disc Brake Kit # K2HR2D. This is for 2,000 lb axles and is a hub and rotor kit, which is needed in order to switch to disc brakes from drum brakes.

  • Parts Needed to Add Hydraulic Disc Brakes to Shorelandr 2-Jetski Trailer
    Since your Shorlandr 2-Jetski Trailer will be used around and most likely backed into water, I recommend going with hydraulic disc brakes because they lack electrical parts. First, if the axle on your trailer does not already have brake mounting flanges, these must be attached behind the existing hub assembly on each side. Most axles have these, but if it does not, you will need to either replace the axle with one that has brake flanges already welded into place or purchase flanges separately...

You can do this by removing one of your current hubs and looking for the bearing number stamped in the face of each bearing as shown in the included picture of the # L44649.

    I have a solution for you, but the # AKUBRK-35-D are 10" brakes and will be too large for the hub/drum assemblies that fit on your axle. Instead you'll want to use the Dexter # 23-398-399 which are a 7" brake assembly that can be used with wheels between 10" and 13" diameter. It sounds like you also need new hubs, so you can use the etrailer Axle Tech # AKHD-545-2-2K which are a 2000-lb capacity and have # L44649 inner and outer bearings to match your specifications.
