So my son and I share a little Q-time over the holidays. "Come on, Son. Lend me a hand to install new rotors on the truck." The fronts went fine. Took it for a spin; no problem. Next day: put the rear end up on jack-stands, take wheels off, bend the ratchet taking off the calipers, but they all come off. Now the rotors. Not so easy this time. Following Haynes book; slack off adjuster nut under the driver's side door. Star wheel adjusted to the smallest (all the way in). Still insanely tight, but manage to get them off. Backing plate is rusted and flaking off. Most of the passenger side plate falls off into my hand. Both brake shoes are worn out. New ones on order. I read there's a recall on the adjuster spring for the shoes, but the fellow at G.M. says I need to have the truck looked at by them if they're going to pay for the part. I invite him and his mechanic over for coffee and a do-nut, and to have a quick look at my truck that's up on jack stands while he's here. He declines.
Anyway, I want to remove the corroded backing plates, and replace them with new ones. It looks like I need to remove the axles, which I am a little worried about attempting. Does anyone know the procedure for this, specifically and in great detail? Alternatively, is there a different fix for this problem? Perhaps not installing the mickey-mouse brake shoes inside of the "hat-rotor" is an option. If so, has anyone done this? Again, if so, how does it affect the vehicle? If driving mainly on roads, how necessary are the backing plates anyway? My plan is to do it all the right way, but I am interested in alternatives. Any ideas and experiences with this system are appreciated.
Thanks in advance.

Reason: add some pics
This should show pics of the two rear hub assemblies, calipers and rotors off, and corroded/disintegrated brake-backing plates. I want to replace the backing plates, and am looking for detailed directions of how to do it. If (and let me stress this part again...IF) the axles do, indeed, need to come out, has someone gone through this before? And if so, what are the steps I need to take?
