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.


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 nickel-chrome-plated 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 a 7-bolt brake flange configuration, 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 Disc Brake Kit Review

Speaker 1: Today we're going to be taking a look at the Kodiak line of Disc Brake Kits. Now, these kits are available in multiple configurations to fit multiple size axles. They're also available in several different finishes.A disc brake kit like this one from Kodiak is an excellent solution to give us good braking force. Typically, for this kit anyway, you're looking at like a 3500-pound axle. A lot of boat applications, you're hauling a boat sometimes miles and miles and miles, and without brakes on your trailer, you put a lot of unnecessary stress and strain on your truck. A braking kit like this allows us to take the stress, the strain off the braking system on our truck but also gives us a safer ride.In this application we've got a surge coupler at the front of the trailer, so as the truck slows it applies the hydraulic fluid pressure, squeezing our caliper together giving us excellent stopping abilities.

The rotors, calipers, and the ceramic pads are all automotive grade, so they're going to be made to the highest standards being sure we get excellent braking capabilities.Now when we compare a disc brake kit like this to a hydraulic drum-style brake, there are several advantages. Of course, we all know disc brakes tend to work better than drum brakes. They lock up less. We typically don't have the moisture being held inside. Especially in a marine application, that hub fills up with water, that moisture stays inside, causes some corrosion issues.

In this situation, once we bring these out of the water, everything's going to drain away. Air can get to it very readily and dry everything up.Another advantage we're going to get with this particular kit over the other disc brake kits available, the material composition is very corrosion-resistant. Our rotor, caliper, all stainless steel, plus they take that a step further, put a Dacramet finish all the way around. So that's going to work out really well, especially in a marine application like this, but also just on a utility trailer, keeping everything nice, corrosion-free. It's also going to be an excellent, excellent choice if you use it in a saltwater-type application.Something else you'll notice, pretty common on automobile applications, not usually on trailers, is going to be the ventilated rotor here.

So you've got two wear surfaces here and here. Those are going to be separated to allow air to flow freely in there and get everything cooled off to give us premium braking performance every time we hit those brakes.All right. With the bracket installed, we can move onto installing our rotor. That's one of the big benefits I like about this kit. You don't have the whole disc with the hub assembly in it.

So if you ever need to replace the disc, you're just replacing the disc, not your entire hub. This is going to fit right on our idler hub just like that, very common on automobile applications. They call this more like a top hat rotor where it it slides over your lugs, and then your wheel is actually going to hold that in and flush.Next, we'll move on to getting our caliper installed. Now the calipers can go either side. You don't have to have a left and a right. You can see we've got a bleeder screw on both sides. We want, of course, for our hydraulic connection to be facing in. Our slide bolts are going to come in this way just like that, and then these two portions are going to go on the back side of our bracket. So we slide that over, bring it in, and then we'll just push our bolts in, line them up with our holes and get them started. Now those do have loctite on them, so you'll just get them started a little bit, and then we'll use a 13mm socket and snug them on down.Now that we've got those snugged down, we'll use our torque wrench and we're going to torque them down to the specifications listed in the instructions. With our brake assemblies in place, it's time at this point to install our tire back on. Now, we do recommend using a torque wrench and torquing these down properly per the 1/2" stud application. Something we've seen, especially in the automobile industry, if you tighten these lug nuts down too much, you might cause that rotor to warp a little, decreasing your performance. That's going to complete our look at the Kodiak line of Disc Brake Kits.

These are the pics I took when I was done. Took two days to do but we'll worth it. I took pics after first load and now it feels good to actually stop with out wondering if the magnets were going to fail. I appreciate the fast shipping . The only thing I had to pick up was 25 feet of brake line,15 feet was not going to be anough . Other then this. I love it. Thank you very much and God bless 462017

Dimensions on caliper are not right , need to do some gridding . It was touching the inside of the rims. Have to move flange back doo to difference in thickness of drum to disc . Have not taken to the hills , but I'm shore it will stop. 436953

Do you have a question about this Trailer Brake?

  • Recommended Electric Over Hydraulic Trailer Brake Conversion for Dual 10K Axles
  • The Disc Brake Kit # K2R1058D13 by Kodiak is the brake set that you will need to use for your 10,000 lb Dexter Torsion axles. When it comes to hardware, like the brake line, I recommend going with the Kodiak Hydraulic Brake Line Kit # 24TA-BLKIT which will wear better than other traditional brands. These lines are very flexible so the line is easy to maneuver under the trailer. The only downfall is that you cannot cut the line due to how hard and risky it is to do yourself. All you have...

  • Changing Brakes from Hydraulic to Electric over Hydraulic on a Boat Trailer
  • There are 2 ways to actuate hydraulic brakes; by either using a surge brake actuator coupler or an electric over hydraulic actuator. A surge brake actuator coupler actuates the brakes by mechanically compressing the master cylinder inside the actuator and applying pressure to the brakes. An electric over hydraulic actuator does the same thing, except it uses the electrical pulse from a brake controller to tell the electric over hydraulic actuator pump when to apply the pressure.

  • Will the Kodiak Disc Brake Kit Part # K2R1058D11 Fit a Dexter 10k General Duty Axle
  • Yes, the Kodiak Disc Brake Kit part # K2R1058D11 will work with your Dexter general duty 10,000 lb axles as long as you have an 395S inner bearing (2.625" inner diameter) and 387A outer bearing (2.250" inner diameter). These brakes are only compatible with a specific type of hub which is the two piece Dexter 8-288. If you also need the hub then you can use the Dexter Trailer Idler Hub Assembly part # 8-214-5UC1. I have attached a review video of the hub for you as well.

  • How to Convert Dexter 10k Drum Brakes to Electric Over Hydraulic Disc
  • We have just what you would need. For idler hubs you would first need to start with the part # 8-214-5UC1 (if you don't have these already) and then to install a disc brake kit specifically for these hubs you would need the part # K2R1058D11 for each axle. This is a Dexter 10k oil bath setup just like what you have. For an electric over hydraulic drum actuator for your trailer you would want the part # HBA16-252-82. That comes with everything electronically. For a 30 foot long tandem...

  • What is Needed to Convert to Electric Over Hydraulic Disc Brakes
  • The Kodiak Disc Brakes # K2R1058D11 may work with your 10,000 lb Dexter axle but you will need to verify this. To do that you can take apart your hub assembly and look at the bearings themselves; wipe away the grease and you should be able to see the part number stamped directly on them. If you are unable to find them, you need to use a digital caliper such as # 301-17068 and measure your spindle to the thousandths of an inch where the bearings ride. You can use the photo I've attached...

  • Does a Trailer have to have Dually Wheels and Idler Hubs for Kodiak Disc Brake Kit K2R1058D11 to Fit
  • Kodiak disc brake kit # K2R1058D11 is designed for 10,000-lb Dexter axles with leaf springs. It will fit either 16-1/2 inch dually wheels or 17-1/2 inch single wheels. So the trailer does not necessarily have to have dually wheels for this kit to fit. The kit fits over idler hubs. Since it fits idler hubs, which are just regular hubs as opposed to a hub with integrated drum, you would need to replace the drum brake hubs with properly sized idler hubs to install this kit.

  • The Kodiak 10K Disc Brake Kit # K2R1058D11 is intended to allow conversion of a Dexter 8-288 idler hub for use with disc brakes. It is compatible ONLY with one specific hub, the Dexter hub 8-288 built between February 1990 and August 2009. If your trailer already has disk brakes then you will be better served by installing appropriate replacement parts for your set up. If you want to let me know the bearing set used in your hubs I can help you locate suitable components.

  • Parts Needed to Convert Tandem Dually Boat Trailer to Disc Brakes
  • Our hub-and-rotor disc brakes kits are offered in various axle capacities including 7000-, 8000- and 10,000-lbs. Since we do not have a 9K kit, which you noted, you can use a 10K kit. Kodiak offers part # K2R1058D11 that works with Dexter hubs that have number 008-288 cast into the hub. This kit fits with 8 on 6-1/2 dually 16-1/2-inch wheels (or 17-1/2 single wheels).

  • Will Disc Brake Kit part # K2R1058D11 Offer More Braking Power than Drum Brakes
  • If you would be going from drum brakes to the disc brake kit part # K2R1058D11 yes you would get much better braking power that would engage quicker and also resist brake fade from heat considerably. Now if you have a drum brake setup that would mean you have a drum brake Hydrastar so you would need to replace yours with the part # HBA16 which has the higher pressure rating that disc brakes require.

  • Does Installing Brakes On Trailer without Them Affect Wheel and Tire Position
  • We generally recommend you stick with the trailer or vehicle manufacturers when it comes to questions like this, but adding trailer brakes does not change the position of the wheel relative to the axle. Hub/drums have the hub face dimension the exact same as the standard hubs. Maybe there's a difference clearance issue between maybe the frame and other components related to the brakes but the wheel/tire location would not change.

  • Can Electric Over Hydraulic and Surge Brake Actuators Be Installed At the Same Time
  • You ask a very interesting question! You are correct that it is technically possible to have both a surge coupler and an EOH actuator connected simultaneously to the same hydraulic braking setup. You are also 100% correct that any manufacturer's risk management team would probably say no. As I see it, the main concern is the lockout on the surge coupler. If you had an electric lockout on the coupler and if for any reason that solenoid or its power connection failed you would have...
