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 Rotors for Easy Replacement

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.

The rotor is made from cast iron, matching SAE specifications. Cast iron is ideal for high-temperature operations and offers a favorable friction coefficient to ensure adequate stopping power. Kodiak's rotors are vented to effectively dissipate heat, dramatically reducing the incidence of heat-related damage.


Calipers

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 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 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.

  • Determining The Correct Replacement Rotors And Brake Pads For A 2022 Grand Design Momentum 349M
    There unfortunately isn't a package for just the rotors and brake pads together so you would need to purchase the rotors and pads separately in order to avoid paying for new calipers as well. To find the correct rotors we'll need a bit of information first. We'll need to know your current stud size and the bearing/seal item numbers if you have an hub with an integrated rotor. If you remove the hub/rotor you can take a look at the outer bearing and the grease seal to see if the item number...

  • Why Is One Rotor Hotter Than All The Others On A Triple Axle Trailer
    Typically when something like this is happening, it will be one of a few things. First will be the pads in this brake caliper have a bit more material than the others and it is making more constant contact with the rotor. This will definitely cause it to heat up faster and more than the others. This will usually happen if the brake pads in just one caliper were replaced recently and is why it is always good to replace all pads at the same time. However, if this was not done recently, you...

    As far as the labeling of the Kodiak Disc Brake Kit - 13" Rotor - 8 on 6-1/2 - E-Coat - 9/16" Bolts - 8K Dexter Disc Kit # K2R89DDE, Dexter is the parent company of Kodiak.
