It looks like you are looking for disc brakes based on the AL-KO/Hayes Disc Brake Caliper -10,000 lbs and 12,000 lbs - Driver's-Side # BP18-050 you asked from. For the disc brake compatible electric over hydraulic actuator I recommend the HydraStar Electric Over Hydraulic Actuator for Disc Brakes - 1,600 psi # HBA1 . If you want the entire kit, I recommend the HydraStar Marine Electric Over Hydraulic Actuator w/ Breakaway and 7-Way RV Harness - 1,600 psi # HS381-9067 or the HydraStar Electric-Hydraulic Actuator w/ Line Kit for Disc Brakes - 1,600 psi # CAR-HBA16-2.

We really only have the caliper # BP18-050 for your application unless you have the 7 bolt brake flange. If you have that flange, then I recommend the Kodiak Disc Brake Kit - 11" Rotor - 8 on 6.5 - Raw Finish - Leaf Spring - 12K - Dexter/Lippert # K2R1258L12. This is compatible with 16 to 17-1/2 inch wheels. Dexter bought out AL-KO Axles years ago so many of their components are compatible like this will be if you have the 7 bolt brake flange. AL-KO had a unique brake flange they put on many of their axles for a while, so we don't have anything that fits that unique 4 bolt flange if that is what is on your 12K axle. Unfortunately we also do not carry the idler hubs compatible with your 12K axle, so if you don't have them you will need to find idler hubs that have 5/8 inch wheel bolts.
