remove wheel, remove cotter pin, remove hub nut, pull drum off. outter bearing and race will just fall out. with hub off remove 4 9/16 screws holding backing plates off. cut two wires running to magnets. Put new backing plates on. reconnect wires, replace everything, probably would do a new bearing pack with new seal since all is apart. And put new cotter pin back in. adjust brake to where a regular turn on the wheel on trailer turns about 1 1/2 times. Job complete....have a beer.

That pretty much says it all. The magnets when new have dimples on the face. If they are worn smooth its best to replace them even if they still work. If replacing the magnets, you might just as well buy new assemblies as the magnets by themselves cost almost as much a complete unit. Also get some heat shrink tubing and slide a piece over the wire before soldering. That will give you a less chance of a problem down the road.
