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, stainless steel 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.


Calipers

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 5-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.

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.

I upgraded my trailer's totally rusted out (after only two years) brakes with this kit. It's now 8 years later and they still look and work like new. If you use your trailer in salt water then these should be put on when new! 546223

  • Inexpensive Corrosion Resistant Disc Trailer Brakes for Salt Water Use and a Boat Trailer
  • The best possible material for saltwater applications is going to be stainless steel but since cost is a factor stainless would not be the way you would want to go. The next best thing is going to be a brake kit with Dacromet finish like # K2R526D. The Dacromet has a 400 to 600 salt spray rating but it is always a good idea to spray them of with fresh water after use in salt water. This kit is designed to fit over idler hubs with a 6 on 5-1/2 bolt pattern and 15 inch or larger wheels...

  • The Location of the Electric Lockout Solenoid with Hydraulic Disc Brakes
  • The Kodiak Disc Brake Kit, # K2R526S, do not have a lockout solenoid on them. The lockout solenoid mounts on the brake actuator and the normally open or normally closed function depends on the solenoid being used. For example, we offer the Titan Solenoid Valve, # T4748800, which is a normally open solenoid. This valve stays open, until it receives power (for backing up situations). The solenoid closes preventing pressure on the brake lines. At this time we do not offer a normally closed...

  • There would be a slight advantage to using 7,000 lb brakes in place of 6,000 lb brakes. The 7,000 lb brakes would not have tow work quite as hard reducing heat build up, but for the weight of your trailer, the 6,000 lb brakes should be able to handle the job well. The disadvantages that you listed are correct as well. When it comes to disc brakes, 7,000 lb brake assemblies will cost more than the 6,000 lb brakes and all of our 7,000 lb disc brake assemblies come with an 8 on 6-1/2 inch...

This hydraulic actuator synchronizes the trailer brakes with those on the tow-vehicle and no electrical wiring is required. Now for the brake lines. There really would be no need to change them because your current lines will support the increased psi.

I took this measurement on this kit's rotors using a precision digital caliper. You'll want to choose a rotor-only kit for the rating of your axle.
