Question:

I have an 2004 Karavan 3100 roller trailer with a Fulton A60 class 4 surge brake actuator for drum brakes on a swing away tounge and 14inch tires. I would like to convert it over to Electric disc brakes. The drum brakes are 5x4.5 3700lbs. What conversion kit do i need to make this happen? Thanks

The 3,700 lb trailer axle makes thing a bit more interesting since the components for it are not always standard. So what I need from you is either the spindle dimensions where the bearings and seal rides or the bearing numbers that are in the hub. With that I will know for sure what parts you'd need to convert to electric over hydraulic disc.

Thanks for getting me that info. It looks like you have 3,500 lb axles on your trailer so for converting your trailer to electric over hydraulic disc you'd want to first start with the disc brake kit part # K2HR35D which fits the spindle you have. Then for the rest of the components all you'd need is the part # CAR-HBA16-2 and you'd have everything covered as this comes with the best actuator, all the lines you'd need, and all of the other electric components needed as well.
