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.

Integral Hub-and-Rotor Assemblies

The integral hub-and-rotor is made from cast iron, matching SAE specifications. Cast iron is ideal for high-temperature operations and offers a favorable friction coefficient to ensure adequate stopping power. Kodiak's rotors are vented to effectively dissipate heat, dramatically reducing the incidence of heat-related damage. Furthermore, machined disc brakes minimize the chance of contamination between the hub and rotor, resulting in excellent performance and long life.


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 Disc Brake Kit Installation

Ten is a boat trailer were going to do a Kodiak disc brake install part number K2HR35D. Before you kept put this conversion kit on, double check to make sure the coupler at the front of your trailer is ready for disc brake use. Sometimes surge brake couplers arent designed for disc brakes. Now were going to start off with our trailer actual strip down it previously had drum brakes on it so we take off the hub and we take off the drum brake. We also pull the brake line out of the way. Were going to point up all the way so that it wont drain all the fluid.

Now were going to move on to our Kodiak kit. We have the parts laid out for one side of axle. We add the drum, brake pads, and a caliper. This is a bracket that will attach everything to the axle and necessary hardware. Were also going to add to the kit which is not included as a flexible line kit thats going to be part number 80910 from red line.

You need two of these kits to do a complete install. Lets start off from our bracket well install it first, two things to make sure of is that this triangle piece here points towards the inside of the trailer and our caliper will be end up point towards the back of the trailer. So go ahead and use the provided hardware to install it. And go ahead and tighten everything down. Now again, install our hub and disc all in one piece and just install just like any other hub.

And we go ahead and reinstall the green cap. All right, now were going to work with caliper we take the one pad and secure it tight that youre going to get just right and it pops into place. And our second pad theyll spring goes into the cylinder and were good to go. We can go ahead and bolt this on to our bracket. We use this bolt right here to run to your caliper and into the bracket.

Would be one on top and would be one at the bottom, all right And snug goes down evenly on both sides and then tighten them down for good. Were going to go ahead and install flexible brake line in this caliper and then we run it at to this 16 line here. You can see how a brake line is pretty long as application would take the original line and coil it up to take it up to the slack. Now when we get done coiling it up, we want to route it were always go down like so coil down still like this. Then we can go ahead and install the bracket for brake line we use the same attachment point here and run everything together. Looks like clipping the place. Its tap down in place then were going to align it to it. Now were done to pass your side, this will go to your driver side repeats the same process. Double lines with gap you go ahead and bleed the brakes. When we bleed the brakes well start with the brakes as far as away from the surge coupler. We go ahead and up on a bleeder is here, the one on the top, it will take feet of rubber line pushing over to the top and the other half into a jar. And then well pump surge coupler until we see bubbles clearing out the lines. Once the brakes are all in bled, were good to go. Lets put the tires and wheels on here and were ready to roll.

  • How to Pick Out Replacement Hubs for a Boat Trailer
  • In order to pick out the correct hub assembly for a trailer you are going to need know a few key pieces of information. The first thing you will need to know is the bolt pattern of your hubs. Since the figure you came up with doesn't match any of the 5-bolt bolt patterns I am going to need to to recheck your bolt pattern. For further info on this check out the FAQ article I attached on this. Next thing you will need to know is what spindle you have on your trailer. In order to do that...

  • Disc Brake Kit and Actuator Recommendation for a Shorelander Boat Trailer
  • The Kodiak Disc Brake Kit # K2HR35D that you referenced is a great disc brake kit to use on your Shorelander boat trailer. This kit and the Titan kits are both great and you wouldn't go wrong with either, I would consider both brands to be about equal. But you will first want to verify that this kit will fit the spindles of your trailer. You will need to pull the hubs and get the bearing numbers to do this. The inner bearing will need to be L68149 and the outer will need to be L44649....

  • How to Determine What Disk Brake Kit will Fit a 1994 EZ Loader Boat Trailer
  • To determine what disk brake kit you would need to convert your current drum brakes to disk you need to first determine what spindle you have on your trailer so that you can match the correct rotor/hubs to fit them. If you pull the hubs off of your trailer and get the bearing numbers (inner and outer) and they happen to be L68149 for inner and L44649 for outer this kit # K2HR35D would fit and work well for you. You will need to make sure that the brake actuator you have has been confirmed...

  • Does Kodiak Offer a Disc Brake Kit with Actuator Like the Titan Brake Kit # T4843700
  • I can put together a brake kit for you that will be comparable to the Titan Disc Brake Kit and BrakeRite II SD Electric-Hydraulic Actuator, # T4843700. Kodiak does not have a brake kit with actuator available. This is most likely because they do not manufacture electric over hydraulic brake actuators. For a comparable kit, you will need the following: Kodiak Disc Brake Kit, # K2HR35D - Qty 2 Titan BrakeRite II Electric-Hydraulic Actuator Kit, # T4835700 - Qty 1 Titan Hydraulic...

  • Can Disc Brakes be Added to the Timbren Axle-Less Suspension Systems
  • The 3,500 lb weight capacity of the Timbren Axle-Less Trailer Suspension System, # A35RD545E, is the weight capacity for the pair, not per side. Disc brakes can be used with the Timbren Axle-Less Suspension systems, however, Timbren does not offer an axle-less suspension kit with disc brakes. If you want to use disc brakes, I recommend buying the Axle-Less Suspension System - 3,500 lbs, # ASR3500S04, and the Kodiak Disc Brake Kit - 3,500 lbs, # K2HR35D. Buying the Timbren Axle-Less...

  • Parts Needed for Disc Brake Conversion on Take 3 Auto Transport Trailer with Three 7,000-Lb Axles
  • I looked up the Take 3 auto transport trailer and it showed it has electric brakes. To convert your electric brakes to disc brakes you will need to use the disc brake conversion kits for 7,000-lb axles with the hub and rotor, hydraulic line kits for three axles, electric over hydraulic actuator, trailer breakaway kit, and a brake controller that is compatible with electric over hydraulic brakes. The disc brake conversion kits will come in pairs, so you will need three sets. These kits...

  • Actuator Recommendation for a Triple Axle Trailer Going from Drum Brakes to Disc Brakes
  • Some drum brake actuators can have the check valve removed or punctured to allow it to function disc brake setups, but this won't work for a triple axle brake setup because drum brake actuators just don't have the volume to activate the disc brakes. Basically you are going to need to replace your actuator since the one you currently have won't be able to activate your new brakes. There is an off-chance that you could replace the master cylinder of the actuator and be able to convert...

  • Inspecting Hubs, Bearings and Spindles on a Boat Trailer
  • Thank you for the measurements you provided, they are very helpful and tell us everything we need to know to recommend parts that will work for you. Based on your bearing numbers and spindle measurements you need a 3,500 lb hub with a 5 on 4-1/2 bolt pattern. The type of hub that you need will depend on whether you have brakes or want a galvanized versus a painted finish. For idler hubs (no brakes), you can use part # 84545BX or # 84545UC1-EZ for EZ Lube spindles. These hubs are also...

  • Trailer Brake Recommendations for a Boat Trailer
  • Since you have a boat trailer I would recommend a hydraulic setup since electricity and water don't mix well. Basically you have two option at this point. You can go with drum brakes which are a bit less expensive or you can go with the superior braking performance of disc brakes. Depending on your budget and the weight of your boat trailer setup either could work well for you. The biggest advantage drum brakes have is the initial cost, disc's advantages are more braking power and less...

  • Choosing Between Disc and Drum Brake Assemblies for 2500 lb Boat Trailer
  • If the boat and trailer weighs less than half the weight of your tow vehicle, the trailer might not have enough momentum during a braking event for surge brakes to be effective. If you're above 1/2 the weight of the vehicle, I'd rather see you go with disc brakes, due to their increased performance. Since you'll be launching in salt water from time to time, the increased corrosion resistance of the Dacromet rotors included in the # K2HR35D Kodiak Disc Brake Kit would certainly be a...

  • Dimension Of Brake Mounting Flange For 7 Inch Electric Or Hydraulic Brakes
  • It sounds like you need the brake mounting flange that needs to be welded to the axle. You will need to know the diameter of your axle to make sure you choose the correct brake mounting flange. If you have a 1-3/4 inch round 2,000 lb axle, the brake flange you need is part # 4-34. This has a 4-bolt mounting pattern with a center hole that measures 1.64 inches diameter. This will work with 7 inch brake assemblies like part # 23-398 for hydraulic and part # 23-48 for electric brakes. If...

  • Will the Kodiak Disc Brake Kit #K2HR35D Work with an EZ Lube Spindle
  • The Kodiak Disc Brake Kit # K2HR35D that you referenced will work with an EZ Lube Spindle as long the components are rated for the same weight capacity, and the dimensions of the bearings are compatible. The type of spindle is not a considering factor, as long as the bearing numbers and diameters are compatible. For example this Kodiak Disc Brake Kit would be compatible with an EZ Lube spindle that is rated for up to 3,500 pounds, and that has compatible bearings, races (which are...

  • Recommended Parts For Changing Surge Coupler To Electric Over Hydraulic Disc
  • When changing your trailer over you will need to do the complete change at one time since some of the parts are made for specific type brakes. I have attached a drawing that shows how the Titan BrakeRite EHB Electric-Hydraulic Actuator for Disc Brakes, part # T4813100 is attached. The # T4813100, has 5 wires that are blue, black, white, brown and purple. You will want to splice the blue wire from the adapter to the blue wire from the actuator. This allows the adapter to intercept the...

  • break kit
  • It might be possible to add trailer brakes to your tow dolly, but based on the pictures you submitted the hubs don't look like standard trailer hubs so I would doubt that any of our brake hubs would mount up to the spindle. Your best option may be to contact Demco to see if they have a recommended way of adding brakes to a tow dolly like yours.
