Kodiak Rotor Diagram

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.


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 4-bolt brake flange configurations, the included mounting brackets are made of heavy-duty, corrosion-resistant dacromate-plated 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 Trailer Brakes K2R35DS Review

Today we're going to review part number K2R35DS. This is the Kodiak disc break kit with the 10" rotor and the 5 on 4-1/2" bolt pattern. Comes with the DACROMET finish and the stainless steel finish. It fits 3,500 pound axles. Now these brake assemblies will make it easy to change from an idler axle to a disc brake axle. disc brakes will deliver better performance than drum brakes. They give you more consistent stopping even at highway speed, and they'll even give you dramatically shorter stopping distances.

Now the maintenance costs are also lower than for drum brakes because you'll have fewer moving parts to maintain, repair, or replace. Now the slip-on cast iron over-the-hub rotors, basically they would just slip on over your idler hub and the wheel studs come through here. They do have a DACROMET coating which will provide superior corrosion resistance for freshwater or salt water use. They do have a 400 to 600 hour salt spray rating on them. Again, they just fit over your standard idler hub, held in place by the wheel, and then the wheel lugs. They do remove easily for maintenance, so there's no need to replace an entire hub and a rotor assembly if only the hub or the this rotor becomes damaged. If you notice, they have to vented design to them.

This will help dissipate the heat better and it will prevent heat-related damage. Now the stainless steel calipers, that's the calipers right here. These are self-adjusting for smooth equal braking. The stainless steel construction does not flex like aluminum. Has nice excellent corrosion protection, so it's ideal for extended marine use. If I move a brake pad out of the way you can see the piston.

It uses a low drag design on the piston which will retract it further than other calipers so it keeps the brakes off the rotor and gives you a cooler-running brake. Plus the stainless steel piston in here is actually about 2-1/4" in diameter, which is about 30% larger than some of the other brands, so it gives you more braking torque than the competition. Then these brake pads, you can see they're a high performance ceramic brake pad design. Now the mounting brackets, they are a DACROMET finish also. They provide strength and durability. You can see how they're designed. They have a nice side support design which ensures that the load is placed on the whole bracket, not just on the bolts.

Has an extra embossing right up here at the top, gives you additional thread contact. When you use these caliper bolts to attach the calipers to here, it will give you a lot additional thread contact, gives you a tight secure mounting caliper. Then also you'll notice it is a 4-bolt brake flange mounting configuration when you do need to have on your axle a 4-bolt brake flange to attach these to. If you don't, we do sell the weld-on flanges separately on our website. Now this kit does include two full brake assemblies. It includes the two DACROMET-plated cast iron rotors, the two stainless steel calipers, the two DACROMET caliper mounting brackets, and the four stainless steel caliper mounting bolts. Now one note I want you to be aware of that when you do switch over to disc brakes, it does require a higher line pressure, usually about 1,500 psi, when compared to the standard drum brakes. To achieve that higher pressure you do want to make sure when you use this system that your brake actuator on your trailer will have at least a 1,500 psi rating. Again, this fits a axle capacity 3,500 pound axle with a number 84 spindle. It will use a wheel size of 14" and larger. The bolt pattern again is 5 on 4-1/2". The wheel lugs that are used would be 1/2". Rotor diameter is 10-7/8". Again, the brake flange configuration, we mentioned earlier, is a 4-bolt design. That should do it for the review on part number K2R35DS, the Kodiak disc brake kit with the 10" rotor, with the 5 on 4-1/2" bolt pattern. .

Products were delivered very quickly. Easy directions and installation. I just wish I would have known extra hardware would be required to install products. Tried to talk with etrailer about the addtional bolts required but they could not offer much information. They did try to answer my questions though. I used these guys twice and will use them again! 10333

  • Best Disc Trailer Brake Kit for Salt Water Use on 3500 Pound Axle
  • The Kodiak disc brake kit # K2R35DS is made up of Dacromet and stainless steel components. Dacromet has a 400 to 600 hour salt spray rating while stainless steel is about as corrosion resistant as you can get. Still when using these items in a salt water environment be sure to hose them off after use with fresh water. For the absolute best in corrosion resistance go with an all stainless kit like # K2R35S. I have linked installation details for you. I have also included a link to our...

  • Disc Brakes Recommendation For 3500 Lb Boat Trailer
  • The Kodiak disc brake kit you asked about, part # K2R35DS, will fit 3500 pound axles with wheel sizes 14 inches or larger. The 10 inch rotors have a 5 on 4-1/2 bolt pattern. The additional 1/2 inch would mean the wheels would indeed be mounted approximately 1/4 inch further out on each axle. The existing hubs along with the bearings and races would have to be removed. You mentioned that the axle has a 4 bolt flange already welded to it. I have attached a photo of how the brake mounting...

  • What Kodiak Brake Hardware is Compatible with Tie-Down Brakes on a Load Rite Trailer
  • I have contacted the two manufacturers but I have been unable to confirm the compatibility of the rotors from one company with the calipers from the other. Depending on how tightly and for how long the original calipers have been frozen in their current position, it may be that your rotors have been damaged by scoring or corrosion. We always recommend that all braking system parts be replaced at the same time using rotors and calipers from the same manufacturer, which ensures both compatibility...

  • Recommendation of Disc Brake Kit for a 4,000 lb Tandem Boat Trailer Hauling a 2,600 lb Boat
  • I would recommend installing disc brakes on both axles to get the maximum braking for your tandem trailer. You will want to check the axles to make sure you have brake mounting flanges on the axles that will allow you to attach the disc brakes. The brake mounting flanges would would have a 4-hole mounting pattern for the brakes and they would be welded to the axle. If you do not have brake mounting flanges on your axles you will have to purchase them and have them installed by a professional...

Basically, all you will need to supply is the bolts that the bracket to the axle. Other than that everything else should be included.

  • Replacement Rotors and Calipers for Oil Bath Hub
  • As long as your hubs are in good condition, a slip-over kit like the Kodiak Disc Brake Kit # K2R35DS that you referenced will work well and be easiest to replace the rotors and calipers. You will want to ensure that the kit matches your hubs. The # K2R35DS kit has a 10 inch rotor with 5 on 4-1/2 inch wheel bolt pattern and is designed for 3,500 pound axles. I've attached the product page for all of our disc brake kits with rotors for you. If the # K2R35DS does not work for your hub,...

  • Will the Additional Width from Slip-Over Rotors Affect the Fit of the Brake Calipers on a Trailer
  • There is some additional width added when using the slip-over rotors like # K2R35DS. This is true on every application that uses this set up. The brackets and calipers are designed for this so they will line up just fine. The wheels and tires will just be 1/2 inch further out on each side. You will need to make sure that your existing axles have brake mounting flanges in order to add brakes to the trailer. If you do not have a 4-bolt mounting flange on each end of the axle, # 4-35, you...
