Ken,
Rear brake cables are pretty easy to replace.  You need to pull the rear
drums, unhook the end of the brake cables from the lever inside the
drum, and then remove the cable from the backing plate.  Unhook the
front of the cable from the metal plate that lives under the center of
the van.  Putting the new one back is reverse of removal.  Sometimes the
part of the cable that goes through the backing plate can be stuck in
there.  If this is the case I usually cut the cable and sheathing with a
pair of wire cutters and then drill the plastic bushing out of the
center of the metal tube with a large drill bit.  If you need new rear
brake cables I have them in stock for $16 per side.  Part number is
251609701C.

Let me know if I can help you.
