Outer Brgs. - 4X #15123 1.250inch I.D. Spindle Lth. - 3.490 Current controller - Prodigy 2006 vintage? Need: 2X Kodiak Disc Brake Kits K2HR526D ? 1X HydraStar Electric Over Hydraulic Actuator HBA16 ? 1X 15foot Brake line kit HS496-152 ? 4X Bearings pairs, seals double lip and caps listed above DBRKHW6SS USA made ? ??? Break away switch ? Have one already but will it work with this setup? Prodigy controller okay? Appears to be per listing What else?? Motivated to buy, just want it right! They are critical brakes to keep my family safe. Please advise Thanks

Thank you for all that detailed information, it is exactly what we need to get you set up with brakes so you can keep your family safe like you mentioned! You initially said you wanted to switch over from drum to disc brakes, but in your question you referenced an electric over hydraulic actuator and brake controller, so it sounds like you want to switch to electric over hydraulic (EoH) disc brakes for the best braking possible.

To get this set up, you will need a new hub and rotor for disc brakes, electric over hydraulic actuator, brake lines, breakaway kit, and brake controller. The reason you need a new brake controller is a brake controller needs to be compatible with an EoH set up. Based on your # 25580 inner bearing and # 15123 outer bearing here are the parts you need, so long as you have a 5-bolt brake flange such as # 4-44-1:

- Kodiak Disc Brake Kit - 12" Hub/Rotor # K2HR526D
- Inner Bearing # 25580, Outer Bearing # 15123, Grease Seal # GS-2125DL
- Bearing Grease # L11380 with Bearing Packer # PTW1218
- HydraStar Electric Over Hydraulic Actuator for Disc Brakes # HBA16
- HydraStar Hydraulic Brake Line Kit # HS496-152
- Hopkins Engager Push-To-Test Trailer Breakaway Kit # 20400
- Tekonsha Prodigy P2 Trailer Brake Controller # 90885 with Plug-In Wiring Adapter # 3015-P

I have added links to video reviews and installs for you to check out as well.
