OP’s post 1 explanation:
“My old 55' seems to be darting back and forth as I am hitting them there brakes.”
One brake is likely getting pressure first........other items not mentioned that effect pressure are the lines both steel and rubber full of rust, partial blockage or severe restrictions.
Even a modern car or truck witha a stuck or stiff caliper piston or slides will cause the dart or drift on first brake application. Drums are far more sensitive to shoe travel, shoe contact points. Adjust the shoes until they are just off of dragging and test drive. Jack the front up , have assistant touch the brake check the wheel rotation, try multiple brake pedal pressures to isolate the wheel that too tight or too loose on rotation.
