Hey Fellas
My 1938 front brake was rusted solid and no coaxing would free it. Lots of PB Blaster and releasing the wheel cylinder and she still was as stubborn as an Arkansas mule.
So.....I had a 1940 same situation and decided I'd try molasses or vinegar dip.
I got 4 gsllon jugs of apple cider vinegar from Walmart at $4 each and a 10 x 8x10 tubby to soak my drum in.
I loosened the 4 nuts on my brake backing plate and wrestled the whole assemble off. I set a brick on bottom to rest the hub on.
I turned drum in dip every 4 hours and overnight. The next day they slid apart.
My son and I made a YouTube video to post soon.
Some people recommend baking soda wash after to neutralized acids.
Drum #2 went into dip today to see if she's still active.
Must be in 65 degree plus air and it does smell like vinegar. I covered my dip with trash bag and old jacket on top
