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.


Mounting Brackets

Designed for axles with 7-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.

I called first to see if a brake kit would fit my trailer. They told me yes. I ordered the brake kit. When I received the kit it was missing pieces so I called Angela W. She was very rude, arrogant, and clearly doesn't know what she's talking about. NO HELP. Turns out the brake kit was not compatible with my trailer like they said it was. I called and told them I needed to send back the kit that came in three boxes and they sent me a label for 1 box. While at the ups store I waited for over 45 minutes on hold and ended up having to pay to ship one of the boxes. $200! I called them early the next day and they told me they would not be reimbursing me for the shipping. Horrible customer service and horrible service. I wouldn't recommend them to anyone. 402204

Ask the Experts about this Kodiak Trailer Brakes
Do you have a question about this Trailer Brake?


  • Converting Drum Brakes On A Dexter Military Trailer Axle With 8 On 6-1/2
  • I would be happy to help you choose the correct brake setup for your Dexter Torflex Axle, however there are no manufacturers that currently make electric disc brakes. All disc brakes are powered by a hydraulic cylinder. If you wish to use a disc brake setup controlled by an in-cab brake controller, you will want to consider the HydraStar Electric Over Hydraulic Actuator for Disc Brakes part # HBA16 and an electric brake controller such as the Tekonsha Prodigy P3 Trailer Brake Controller...

  • Parts Needed to Add Disc Brakes to Trailer with Dexter 12K Axles w/ Electric Drum Brakes
  • The Kodiak # K2R1258L12 Disc Brake Kit is compatible with a 12K Dexter axle with a 7-bolt brake mounting flange. Your current wheels/hubs should have an 8 on 6-1/2 inch bolt pattern. You'll also need an electric over hydraulic brake actuator, a brake line kit, a break away system and a brake controller that's compatible with electric over hydraulic brake systems. For the electric over hydraulic actuator, I'd recommend going with the Hydrastar # HBA16. Our install techs have found...

  • Will Kodiak Disc Brake Kit # K2R1258L12 Fit 12 Dexter Axle
  • As long as your Dexter 12k axles have idler hubs installed on them Kodiak Disc Brake Kit # K2R1258L12 is a confirmed fit that would work well. An idler hub is a hub that does not have a brake drum or rotor built into it.

  • What Components Are Needed To Convert Electric to Hydraulic Disc Brakes On 12K Trailer
  • I have attached a link to a helpful article that explains everything that is needed when adding hydraulic disc brakes to your trailer. In addition to a kit like part # K2R1258L12 you will need to make sure you have the right brake mount flange, and you will need to add hydraulic brake lines to your trailer. You will also need a surge brake actuator like part # T4750820 installed on your trailer frame. I have attached links to the brake lines we offer, and to the actuators we offer.

  • Will Kodiak Disc Brake Kit K2R1258L12 Fit a 12K Rockwell Axle on PJ Trailer
  • I am assuming that one of the axles has brakes and the other does not. If that is the case and the axle that does not have brakes has idler hubs then you can use Kodiak kit # K2R1258L12 provided that the hub has an 8 on 6-1/2 bolt pattern and brake mounting flanges on the axle. You will also need some addition brake line and related parts such as what is included in kit # 15SI-BLKIT. Or it may be more beneficial to go ahead and replace all the lines with a tandem axle kit # 24TA-BLKIT.

  • Replacement Caliper Recommendation for Kodiak Disc Brake Kit part # K2R1258L12
  • The replacement calipers of the Kodiak kit part # K2R1258L12 that you referenced is # KDBC2250E. The kit you have does have a 3 year warranty on it that protects it from manufacturer defects. Do you know why yours started to leak?
