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 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.

Video Transcript for Review of Kodiak Trailer Brakes - Disc Brakes - K2HR12A11-120DW

Today we're gonna take a look at the Kodiak Disc Break Kit with the 11.35" rotor for 12,000 pound AL-KO axles with the #120 spindles. Now, these brake assemblies make it very easy to change from an idler axle to a disk brake axle. Disk brakes will deliver better performance than drum brakes. It gives you more consistent stopping, even at highway speeds. And also, dramatically shorter stopping distances. Also, the maintenance costs are lower than for drum brakes because you have fewer moving parts that you have to maintain, repair, or replace.Now, this kit is a slip-on cast iron over the hub rotor.

It's designed to fit over idler hubs. They are held in place by the included bolt. And, the rotor space, which is this section right here I've already bolted to the rotors, these rotor spacers will ensure proper positioning of the rotor. It's also a vented design rotor, so it does prevent heat related damage with the vented design. That vented design will effectively dissipate the heat.Now, on the calipers and the caliper brackets, they have an E-coat finish on them, which will provide corrosion resistance for fresh water and limited salt water use.

The calipers are cast iron caliper, they are self adjusting for smooth equal braking. And, the cast iron construction does not flex like aluminum. They do offer a low drag design, which will retract the piston further than other calipers for cooler running brake. They do use the stainless steel pistons, you can see right down here. These are 2 1/2" in diameter, and that's about 30% larger than other brands.

So because of that it'll give you more braking torque than the competition. They do use these high performance ceramic brake pads on the calipers.Now, these mounting brackets, these caliper mounting brackets, they are ductile iron. They provide strength and durability. They are a side support design, so it ensures the load is placed on the whole bracket, not just the bolt. And, they do give you the extra embossing for additional thread contact to ensure a tight secure mounting for the caliper guide bolts.Now, this kit does include everything laid out here on the table.

It's for two full brake assemblies. You get the two machine finish cast iron rotors, the two rotor spacers, the two E-coated cast iron calipers, the two E-coated ductile iron caliper mounting brackets, the four stainless steel caliper mounting bolts with brackets, and then these two screw-on center caps.Now, a hydraulic brake actuator and brake lines are required for your brakes to be activated. Those we do sell separately if you need them. If you do need them, they do require PSI rating of at least 1500 PSI. These parts are made in the USA. A few specs on this, they are designed to fit a 12,000 pound axle, and it's an AL-KO type with a #120 spindle. The rotor diameter on these is 11.35", the pilot hole diameter in the back of the rotor is 4.88". But, that should do it for the review on the Kodiak Disk Brake Kit with the 11.35" rotor for 12,000 pound AL-KO axles with the #120 spindles.
