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.

Very well made products.;4

A little more money than aftermarket but well worth the money

Thank you for your knowledge help. Transaction was smooth and price was good. Will definitely be purchasing from you guys again.



by:

Brakes seem heavy-duty & solid; they are cast with only some surfaces machined, so the product has a bit of a rough look, but I don't expect that to affect function



by:

You folks are great at Etrailer. Keep up the great work. Good products at fair products, with great service.

Cathy helped me find the right brake parts for my trailer. She got it shipped to me on time and delivered when I needed it most, right before an out of town trip. She is extremely personable and is an awesome example of what customer service should be. I hope her boss reads this and gives her a nice big bonus !!!! She deserves it.



by:

Big upgrade to my non stainless breaks before! My only complaint is I did have to run to the hardware store and grab 10 3/8”x1” bolts and nuts. The install takes a few hours and 2 people to bleed the breaks.



by:

Seeing how quickly high end boat trailers rusted out from salt water when I was a kid in the 1960s, I built a trailer for myself using heavily galvanized junk yard steel and took the springs apart, slathering each leaf with a very viscous grease. This trailer lasted for over twenty years of salt water use. My current triple axle aluminum trailer has needed new hubs, calipers and rotors about every 4 years due to corrosion even with good flushing after each use, so I ordered Kodiak SS 12" rotors, SS calipers and SS caliper mounting flanges. On previous brakes the actual brake pad material had been separating from their metal backing plates after maybe 4 years due to corrosion, so I was very pleased to test the new brake pads and find the pad material is bonded to what seems to be SS backing plates!! The kit however, did not comes with SS bolts to attach the caliper mounting flanges to the wheel bearing hub mounting flanges. Finding 1.25' long by 3/8" diameter SS bolts and SS nylock nuts was a time consuming nuisance so I suggest including them with the Kodiak kits. I have 12 trailers and tow a couple of boats including a 32' twin 300 hp boat rig between the Florida Keys and Chesapeake Bay seasonally and the conversion from surge brakes to electric over hydraulic using a progressive brake controller has been a MAJOR safety improvement.



by:

Really expensive solution for my boat trailer that gets dunked in saltwater alot. Will see how well it holds up over time but everything fits and works well so far



by:

so much better then the steel rotors and calipers. They look like the day i put them on. I am a commercial operator and the steel ones just don't last always a problem with salt and seizing calipers. The SS are just incredible and well worth the extra bucks hands down



by:

Perfect fit, delivered as promised.



by:

Greg S and ALL the etrailer staff is top-notch.
The
product is awesome, fitment is perfect...I really wish the kit would have come with twelve new stainless bolts and lock washers for the brackets but it didn’t.



by:

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!



by:

Great product and outstanding customer service. Our trailer was down in the peak of our fishing season, and Paula was excellent at assisting us in getting this product overnighted. She checked the warehouse status to make sure we would get the product on time. It is so nice to receive that level of customer attention, thank you!!



by:

Outstanding kit for saltwater use. 1 year, no surface rust. I did cover everything in grease as another layer of protection. Only complaint is the cost of this kit.

  • Recommended Disc Brakes for Shoreland'r Boat Trailer Used In Salt Water with 3,225 Lb Axles
    The Kodiak Disc Brake Kit part # K2HR35DS is a great option to replace the disc brakes on a Shoreland'r Boat Trailer. It has dacormet and stainless steel finishes so it will hold up to salt water just fine. The hubs and rotor are integrated into one another which will make for easy replacement. Please note, you'll also need the Bearing Kit for Trailer Brakes part # DBRKHW35EZ to complete the installation.

    Yes, you can keep your oil bath hubs and use the Kodiak disc brakes; you mentioned a salt water environment and stainless steel brakes so you have two options, with the all-stainless steel being the best in terms of corrosion resistance, as you can see by the salt spray ratings of each: - 300- to 400-Hour Salt-Spray Rating: Dacromet and Stainless Steel: Kodiak Disc Brake Kit # K2R35DS - 1,000-Hour Salt-Spray Rating: Stainless Steel: Kodiak Disc Brake Kit # K2R35S In order to be sure...

  • Troubleshooting Disc Brakes Not Releasing
    If your disc brakes like the Kodiak Disc Brake Kit # K2R35S are not releasing it is likely an issue with the hydraulic actuator. Oftentimes this is the shock of the actuator having gone bad so it won't release all the way, so that would be the first thing to check; you could possibly replace it if that is the case. For example, if you had a Titan Model 60 Actuator you could use the Replacement Shock Absorber for Titan Model 60 Brake Actuators # T2336200.

  • Stainless Steel Disc Brake Kit Solution for 3,500 lb Axle of Single Axle Boat Trailer
    For a surge coupler replacement that would work well on your Rocket 1835 trailer the Dexter part # DX63FR would be a really great option. Then for a stainless slip-on disc brake kit the part # K2R35S would be a great option as well. The only thing else you'd need is a disc brake kit like the part # 18SI-BLKIT which is a flexible hose line kit so it's easier to install.

  • 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.

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.
