One of my this winters to do list things was to replace shoes, cylinders, springs and check/replace bearings.
I have done my homework and used search and check those incredible GMCmotorhomeinfo pages, but it seems I found again too much information.
We have stock drums in rear and stock discs and calipers in front. Since i have been suspended without paycheck over this winter, my budget did not allow to make big upgrades. I try to find parts as much as possible locally from Finland to avoid shipping and customs. I have been a parts monkey in our local USA-parts shop 15 years ago but still have friends at bigger parts warehouses in Finland, so I can get good discount on parts they have in stock.
Currently almost everyone seems to have 6-wheel discs in their coaches, but I believe someone still has all correct part numbers in drawer.
They stock mostly Raybestos brake parts here, but I think I can interchance other manufacturers numbers.
So brave volunteers step on and complete missing numbers:
-Brake shoes: 462 riveted
-Cylinders mid axle 1 1/16": Wagner wc86000
-Cylinders rear axle 15/16": Raybestos 37048
If understood right, it does not make any sense to chance bigger cylinders in rear without other modifications (control arm kit, mastercyl.) ?
-Spring and hold down kit:
Are these springs by Toronado or STW?
-Parking brake cable mid:
-Parking brake cable rear:
Are these cables GMC specific or loan from some other GM vehicle?
Conduit in our rear right is cracking in pieces, I´d like to put Branscombe parking brake update but can´t afford it right now.
-Rear axle seal:
If I remember right they stock mostly National seals, was that wrong measure appearing in other brands than Timken?
Still have feeling we found quite good coach at decent price with low miles and without shadetree mechanic fixes, but sometime it feels too much parts are aging out at same time. I chance body insulators at weekend and noticed I have to also chance shock bushings (KYB´s), and stabilizer bushings and end links.
Think I know how it feels to try fix Hoover dam just with empty wallet.
I appreciate all help with these (and probably ask more tomorrow..) !

I got the cylinders from Applied, and replaced them when I put the reaction arm kit on, using the smaller in the rear. No more skids, it stops properly now.

I can't help you. I had problems sourcing all the right stuff, because of way too much info out there. I also know nothing about the parking brake cables and parts, but i believe them to be gmc motorhome specific.
I got spring kits, and still could not exactly match up with what was on my coach. I used 75% out of the kit and kept a couple old springs on the rear..
hardware kits:

raybestos uses the same part #H7028
for the rear axle seal:
Chicago rawhide 21771 seal
try to double check my numbers.

Thank you guys!
Johnny, reaction arm kit is on the Santa´s wish list, but it´s long time to christmas 
Jon, that part number for spring kit sounds way too familiar, I go to check my FSJ-Jeep parts pile and there was one set!
We have also ´96 Roadmaster stw and I have stocked service parts for it, and found another set of springs from own stock.
Next I remember that I bought from auction years ago big box of new bearings to FSJ and gotcha: Inner bearings and cups were waiting for me there!
It was quite funny, I should remember that they all use same shoes, so there must be other same parts too.
Now I feel like winning in lottery, shopping list bit shorter now.
Those were this days good news, then bad news: Rear brake hoses looks to be factory originals, found label on right one: Inland DOT 76/3.
They look ok outside, no cracs or fading, but I don´t mind to close them with pliers anymore when chancing cylinders.
