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, 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 4-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 Trailer Brakes K2R35S Review

Today we're going to review part number K2R35S. This is the Kodiak disc brake kit with the 10" rotor, 5 on 4-1/2" bolt pattern, stainless steel finish, and it fits 3,500 pound axles. Now these brake assembles will make it easy to change from an idler axle to a disc brake axle. Your disc brakes will deliver better performance than drum brakes, and it will give you more consistent stopping even at highway speeds, and it's also a dramatically shorter stopping distance. Also, the maintenance costs are lower than for drum brakes because you'll have fewer moving parts to maintain, repair, or replace. Now this kit is all stainless steel construction, which is very durable and rust-proof. It's ideal for extended marine use.

All the parts have a 1,000 hour salt spray rating. Now these over-the-hub rotors, these are a slip-on over-the-hub rotor. You can see you just line it up with the wheel studs on the idler hub and this will slide right over. Fits over the standard idler hub and is held in place by the wheel and the wheel lugs. You can remove this easily for maintenance.

There's no need to replace an entire hob and rotor assembly if only your hub or the rotor becomes damaged. If you notice on this rotor also it is vented so that will effectively dissipate the heat, and it prevents any heat-related damage to the rotor. Now on the calipers they are also a stainless steel construction. They are self-adjusting for smooth equal braking. The stainless steel construction does not flex like aluminum. Gives you a absolute corrosion protection so it's ideal for the extended marine use.

Also, the piston is a stainless steel piston that's in here. It has a low drag design, which means it retracts the piston farther than other calipers, keeps the brake pads off the rotor so it gives you a cooler-running brake. Now that stainless steel piston right here, right down in here, it is 2-1/4" in diameter, which is about 30% larger than other brands, so that will give you more braking torque than the competition. Then the brake pads, right here here you can see they are high performance ceramic brake pad. Now the stainless steel mounting brackets, they will provide strength and durability. You notice them, they do have a nice side support design. This will ensure that the load's placed on the whole bracket, not just on the bolts.

Up at the very top it does have some extra embossing for additional thread contact, so when you use your caliper bolts to attach the caliper to this bracket it will ensure a tight, secure mount. If you notice this bracket it is a 4-bolt brake flange mounting configuration, so this will need to be put on an axle that has a 4-bolt brake flange. Now if your axle doesn't have a flange, we do sell a weld-on flange separately on our website. No this kit does include two full brake assemblies, so it's actually two stainless steel rotors, slip-on rotors, two stainless steel calipers, two stainless steel caliper mounting brackets, and then the four stainless steel caliper mounting bolts. Now one note I do want to mention is that when you do switch to disc brakes they do require a higher line pressure, about 1,500 psi, when compared to the standard drum brakes. What you need to make sure is that on your trailer you will have a brake actuator that will at least have a minimum of 1,500 psi rating for it to work correctly. A few specs on this. The axle capacity it fits on is 3,500 pounds. It does fit the axle with a number 84 spindle. does use a wheel size of 14" and larger. The bolt pattern is a 5 on 4-1/2" bolt pattern. The wheel stud size is 1/2", so it does use 1/2" lung nuts. Now the overall diameter on one of these is 10-7/8". Again, just to mention on the brake flange, it does use the 4-bolt brake flange configuration. That should do it for the review on part number K2R35S, the Kodiak disc brake kit with the 10" rotor and 5 on 4-1/2" bolt pattern, and the finish is in stainless steel. .

Ask the Experts about this Kodiak Trailer Brakes


  • Can Electric Trailer Brakes be Used in Salt Water when Adding a Weight Distribution System
  • There are several options for using a weight distribution hitch with your boat trailer and keeping the brakes working properly. If you want to go to electric brakes you can, but you will need to be sure to rinse the brakes with clear water each time you use the boat in salt water conditions. I normally do not recommend electric brakes in wet conditions but it can be done. Electric brakes will corrode much faster and are not available with galvanized parts like hydraulic drum brakes are....

  • Is the Titan Disc Brake Kit # T4843400 Good For a Salt Water Boat Trailer
  • In the Titan disc brake kit, # T4843400, the hubs and calipers are silver cad plated, the actuator is zinc-coated, and the lines are all steel. This is not an ideal set up for a salt water application. The best option would be to go with stainless steel parts. You could start with Kodiak disc brakes, # K2R35S. For 2 axles you would need 2 sets. They fit 14 inch and larger wheels and will fit a hub with a 5 on 4-1/2 bolt pattern. The rotors are the over the hub style. The actuator...

  • Complete Disk Surge Brake Setup Recommendation for a Rogue Tandem Axle Boat Trailer
  • We have everything you need, just not in one kit. For a disk brake kit that will bolt up to your 4 bolt brake flanges and will slip over your 5 on 4-1/2 inch bolt pattern you would want the part # K2R35D for a dacromet finish. Or if your trailer will see salt water I would recommend the stainless steel kit part # K2R35S. You will need a quantity of two of these kits for both axles. For a brake line kit you will need the part # DM5425. And then for a surge brake actuator you would...

  • Recommend Kodiak Disc Brake Kit To Fit Trailer With 13 Inch Wheels
  • The reason why the Kodiak Disc Brake Kit - 10 Inch Rotor, part # K2R35S, will not fit 13 inch wheels is because part # K2R35S uses a slip on rotor, so the assembly is slightly bigger making the caliper sit out further. You would need a hub and rotor assembly disc brake kit. The caliper and rotors you would need for your trailer with 13 inch wheels is the Kodiak Disc Brake Assembly, part # K1HR35S. You would need to order a quantity of 2 of part # K1HR35S, as it is sold for one side....

  • 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...

  • Availability of Rust-Proof Electric Trailer Brake Assemblies for Use in Sea Water
  • Generally electric trailer brakes are not ideal for use in or near water. Boat trailers generally use either drum or disk hydraulic braking systems to avoid mixing water and electricity, which generally do not like each other. The best brakes for salt water environments are stainless steel disc brakes, such as # K2R35S from Kodiak. It would not be a good idea to mix brake components from different manufacturers since these parts would not have been tested together.
