Unlikely the pressure regulating valve is not working like it should ..
Should at least be considered.
I get the rear shoes pretty close to the drum, never have a problem with
the rear brakes.
How were they adjusted ?
were all the friction spots likely lubed with anti-seize..
like where the shoes slide on the backing plates? or every pivot point ?
was the parking brake cable adjustment backed off some..
shoes adjusted very carefully, then cable adjustment done ?
the original poster could examine the brakes shoes to get an idea about
contact area...
more contact area the better.
they should work. Master cylinder comes to mind ..to at least consider.
