35 Chrysler Airflow AND 51 Plymouth: grabby brakes

Howdy again, Guys!

On both of these cars, when started up and driven after a long spell the brakes will grab causing violent swerves to one side or another. A big time mopar guy said the cause was the drums being about worn out. I read that as "plumb worn out". He said about all I could do was drive the cars until the shoes set into the drums, but somehow left me with little hope, especially when asked where I could get replacement drums. He just said, "good luck".

Is there a way out? I suppose I could get some drums for the 51, but on the Airflow--a beautiful car--I have not driven it since for safety reasons.

Did I just take it up the old.... exhaust pipe here? Or is there hope?

Thanks again,
