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.


Integral Hub-and-Rotor Assemblies

The integral hub-and-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. Furthermore, machined disc brakes minimize the chance of contamination between the hub and rotor, resulting in excellent performance and long life.


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.

Video Transcript for Kodiak Trailer Brakes - Disc Brakes - K2HR89AE Review

Speaker 1: Today I'm going to take a look at the Kodiak E-Coat Disc Brake Kit with the 13" Hub and Rotor, 8 on 6-1/2" bolt pattern, for 8,000 pound AL-KO/Quality axles.Now, these brake assemblies will make it very easy to upgrade from drum to disc brakes for better performance. Disc brakes will deliver better performance than drum brakes, because it will give you more consistent stopping, even at highway speeds, and dramatically shorter stopping distances. Also, the maintenance costs are lower than for drum brakes because you have fewer moving parts to maintain, repair, or replace.This kit will include everything shown here on the table. It includes two full brake assemblies. You get the two E-coated cast iron hub and rotor assemblies, two E-coated cast iron calipers with the four stainless steel caliper mounting bolts, and then two of the E-coated ductile iron caliper mounting brackets.Now, the hub and rotor, it's an integral hub and rotor. It's all one piece.

This will minimize lateral run-out, prevent warping. Provides a nice smooth ride with the balanced hub and rotor. It does use industry standard bearings and seals that we do sell separately. Now, the bearing races are pre-installed in the hub and rotors, so they're included, and then the oil caps here are also included.Now, this rotor will prevent heat-related damage. It uses the vented design.

This will effectively dissipate the heat. It does include the wheel studs. The lug nuts to install your wheel are sold separately. The calipers are a cast iron caliper. They are self-adjusting for smooth, equal braking.

The cast iron construction does not flex like aluminum. It is a low-drag design, so it retracts the piston further than other calipers for a cooler running brake.The piston in it . Let me see if I can turn this over, take out the brake pad. There's your piston right there. It's a silver cadmium piston.

It's 2-1/2" in diameter, which is about 30% larger than other brands. It'll give you more braking torque than the competition, and again, it comes with the high performance ceramic brake pads.Now, the caliper mounting brackets that'll hold the calipers, they're a ductile iron caliper mounting bracket, provides strength and durability. They are a side support angled design, so it ensures that the load is placed on the bracket, not just the bolts. It does give you extra embossing for additional thread contact to ensure a nice tight, secure mounting for your caliper guide bolts. If you notice, it is designed for a four-bolt brake flange mounting configuration.Now, this assembly does require hydraulic brake actuator and brake lines, which we sell separately. They are required for the brakes to be activated. You do want to make sure the actuator and the brake lines that you get have at least a 1500 psi rating.These parts are made in the U.S.A. Again, this is designed to fit 8,000 pound AL-KO/Quality axles with the number 42 spindle. The wheel size that'll fit on these are 16" diameter and larger. Bolt pattern is an 8 on 6-1/2" bolt pattern. Rotor diameter, from this edge to this edge, is 13", and the wheel stud size is 9/16".But that should do it for the review on the Kodiak E-Coat Disc Brake Kit with 13" Hub and Rotors, 8 on 6-1/2" bolt pattern, for 8,000 pound AL-KO/Quality axles.
