1998 caravan parking brake

Cannot get to hold, replaced rear shoes, wheel cylinders, hardware, front pedal assembly, remachined rear drums, have rears adjusted snug. Any special way to set parking brake auto adjuster after work, or any known issues.

cant get to hold or cant get get lock when you depress parking brake pedal?

Pedal holds all the way down and stays locked until released, but vehicle rolls in drive at idle. Can't figure out how to get slack out of cables, you see all the new parts. Do I have stretched e brake cables? no one seems to have seen that.

pedal goesa all the way down how is service brake pedal misadjusted rear brakes will cause cables to seem stretched or it is possible cables are stretched? stupid question but are the parking brake arms between the shoes in right?

Bottom and top struts are between rear shoes correctly, my problem is to figure out where my excess slack is coming from at e brake. e brake is self adjusting through loaded spring at e brake pedal.
