Did you run the adjusters as loose as possible? Old drums may get a ridge around the inside. If they are Huck brakes (should be) there are 2 adjusters per wheel cylinder. Both ends are RH threads. Looking end-on the cylinder, turn the star wheel counter-clockwise to loosen the shoes.
Current fleet (subject to change w/o notice) \'49 GMC 3/4-Ton , 60 Austin Healey Frog-eye Sprite (some assembly required), 2011 Dodge Avenger, 2015 Jeep Cherokee. No, they don't all run. My other ride is a (B737)no, (B767)no, A320.... Update... was Embraer E190, now Boeing B787. Knowledge is a wonderful thing, but ignorance means you don't know you can't do something.
