Replacing drum brakes ???
Need to replace brakes on my 5er, it has Lippert axles, drums are 12". Can I just replace the brake shoes or do I replace the entire backing plate, brakes, magnet all of it. Where do I go for parts? ...

Do you recommend reusing your drums? If so, how many times? Do you get them turned? Does turning include resurfacing the magnet track?
Might do brakes this spring. Not sure if I should do new drums, even though they look good. Seems like a set of drums with hubs and bearings costs as much or more than the brake sets.
The maximum diameter of the drums should be on the drum, normally they will have plenty of material to allow turning. The magnet track (armature) is a different story, they are often grooved and only .030" is allowed for removal and few shops have the ability to get the high finish required.
When replacing bearings, use only Timken, not the cheap Chinese junk sold by most stores, eTrailer included.
When burnishing new brakes, the manufacturer suggests doing repeated hard stops to get them seated. The problem with that is the new magnets are not yet seated and hard stops will work them hard, causing grooving of the armature. Now the new drums are as ugly as the old.
