The Kodiak # K2R79 disc brake kit is designed to slip over an idler hub, not a hub drum. A 7K Dexter axle uses the 25580 inner bearing and a 14125A outer bearing with a 10-36 grease seal.

To make that particular kit work, you'd need to remove the existing hub drum and electric brake assembly and install an idler hub that's compatible with your existing axle spindles, like part # 42865-KIT.

You'd be better off going with a hub/rotor kit. I'd recommend using the Kodiak # K2HR712E and the # BK3-200 bearing kit. For a tandem axle fifth wheel, you'd need two of the disc brake kits and 4 bearing kits.

I've linked you to a helpful FAQ article on adding hydraulic brakes to a trailer.
