Bad Brake howl

[acesneights1]

Hey guys,
Newbie here.  Need some help.  I have a 1987 Ford L8000 34k gvw Single axle spoke wheel.  I have changed the drum, the chamber, the hardware and the linings twice and the truck is good for about 3-4 days then it gets louder and louder to the point where it makes a garbage truck sounds quiet.  It is on fuel oil delivery truck.  I have done many many brake jobs over the years and never seen anything like this.  Any ideas ? I am the only one who drives the truck and it is not abused.

What style of brakes does the truck have.
Does noise start with heavy application or light application.

Both rear wheels.  They are Q kit 23,000lb linings.  The first set i tried was carlisle the second not sure.  After new lining install they are quiet for a few days then get progressively worse.  They are quiet in the morning but after a few miles the get loud.  Light application.  Hard application no noise.  Drums are new.  No noise going backward that I can tell.

A good heavy truck brake supplier should be able to set you up with all the correct parts. It does sound like the brakes are glazing up like a packer or shunt truck commonly does. I have learned from an old British foreman one time who cut some slight criss cross lines along the shoes & that seemed to help. I think it is the speed that the units are subjected to daily.
