The Kodiak Disc Brake Kit # K2R1258L12 will allow you to convert one of your 12K Dexter axles from drum to disc brakes. This kit will mount to your Dexter Hub 008-214-09 once removing the drum section and brake assemblies. You will need 2 kits as your trailer has tandem axles. Be sure to check your bearings and races and replace as needed. You will want to install 4 new oil Seals # 10-56 as they often become damaged during the removal and installation process.

Inner Bearing # 3984
Inner Race # 3920
Outer Bearing # 28682
Outer Race # 28622
Oil Seal # 10-56
Oil # XLPROLUBE

You will need a Hydrastar Vented Marine Electric Over Hydraulic Actuator for Disc Brakes # HS381-8067. Depending on your truck you may need the Actuator Adapter Module # HBA-CAM to work with your factory brake controller. If you can let me know what truck you have I can verify this for you. For the brake lines we have a 15' Main Line Kit # HS496-152 and 25' Main Line Kit # HS496-252 depending on how far your actuator is from your front axle.

On the label for your axle there will be the capacity listed. If you see just 12k or 12,000 lb axle then the #K2R1258L12 would work. If you see 12k HD or heavy duty then it would not.
