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.

Video Transcript for Kodiak Trailer Brakes - Disc Brakes - K2HR2D Review

Speaker 1: Today we're gonna take a look at the Kodiak Dacromet Disc Brake Kit with the 8" hub and rotor, five and 4-1/2" full pattern for 2,000 pound axles. Now this brake assembly makes it very easily to upgrade from drum brakes to disc brakes for better performance. This brakes will deliver better performance than drum brakes cause you get more consistent stopping, even at highway speeds. And dramatically shorter stopping distances. Also, the maintenance costs are lower than for drum brakes cause you have few moving parts to maintain, repair and replace.Now this kit will include two full brake assemblies. It includes two dacromet plated cast iron rotors.

The two dacromet plated cast iron hub spacers that are already installed. Two of the dacromet plated cast iron calibers with the four stainless steel caliber mounting bolts and then inaudible 00:00:47 two dacromet plated ductile iron caliber mounting brackets. Now the dacromet plating provides superior corrosion resistance for fresh water or salt water use. Right here they have a slip on cast iron over the hub rotor that'll mount, two a these included, spacers.The hub spacers will replace your standard ivor hubs. Now this does use industry standard bearings and seals that we do sell separate on our website.

Now the bearing races will already be pre-installed into the hub. The rotors, you can see are vented to prevent heat related damage by dissipating the heat. And the calibers they are a cast iron caliber. They're self adjusting for smooth equal braking. The cast iron construction does not flex like aluminum.

It is a low drag design so it retracts the piston further than other calibers for a cooler running brake.And I just wanna show you . Let me take the aluminum pads out here. Here is the stainless steel piston in here. It's 2-1/4" in diameter. It's about 30% larger than other brands, sort of give you more braking torque than the competition and they do come with the high performance ceramic brake pads.

Now the ductile iron mounting brackets, they do provide strength and durability. They give you side support angle design that'll ensure that the load that the load is placed on the bracket, not just the bolts. Does have extra embossing for additional thread contact to ensure nice tight secure mounting for the caliber guide bolts. And you can see it is a design is for a four bolt brake flange mounting configuration.Now hydraulic brake actuator and brake lines are required for these brakes to be activated. We do sell those separately on our website. You do wanna make sure that the brake actuator and the lines that you get will have to have at least a 1500 psi rating. These parts are made in the U.S.A. Again, it's designed to fit 2,000 pound axles. The wheel size it'll fit on these is anywhere from 10" to 13" diameter. The bolt pattern is a five around 4-1/2" bolt pattern. The rotor diameter edge to edge is 8" and the wheel stud diameter is a 1/2". But that should do it for the review on the Kodiak Dacromet Disc Brake Kit with the 8" hub and rotor, five, one 4-1/2" bolt pattern for 2,000 pound axles.

Do you have a question about this Trailer Brake?

  • 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. The Kodiak Disc Brake Kit # K2HR2D is designed for 2,000 lb axles and will require your current hub have inner and outer bearing parts L44649, with a grease seal diameter of 1.500 inches. When you remove your current hub and drum you need to take a look at your bearings and they should have the part number stamped right on them. That will let you know the correct kit you...

  • Disc Brake Kit Recommendation for Spindle that Measures 1 inch in Diameter
  • What is the diameter of the spindle where the inner bearing rides? If it is also 1 inch we have the Kodiak disc brake kit part # K2HR2D that will fit the spindle. Otherwise if you have a different dimension there we wouldn't have a fit.

  • 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.

  • 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 #...

  • 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.

  • 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. This particular kit is the only...

  • Aluminum Car Trailer Restoration and Replacement Brake Recommendations
  • Thanks for the feedback, and I am glad that you are finding our website helpful! For your 1989 Trailex CT-7031 all aluminum trailer with the specifications that you provided there are three options for restoring or replacing the brakes for this trailer. The three options are similar to what you mentioned, and are: 1.Hydraulic Drum, which is the most cost effective. 2.Hydraulic Disc, which is more expensive, but provides better performance. 3.Electric drum, which is most cost effective...

  • 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.

  • Selecting Compatible Disc Brake Kit for 1977 Trailer with 13-Inch Wheels
  • 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...

  • 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...

  • 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...

  • 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...

  • 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...

  • 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.
