Would think the brake cam is sticking or one or both of the cables are sticking

Lube cables and make sure you haven’t got your brakes adjusted too tightly.

Have you replaced the shoes on it and maybe didn’t get thr adjustments right?

That question could turn into an entire 300 post thread with some name calling ----- a grease that is water proof would be my first concern , I like marine grease , anti-sieze would last for a while

As others have mentioned it could be a seized cable or cam. Another likely candidate is worn parts. A worn out cam will round off and not return because it is pivoted too far for the spring tension on the shoes to do it. Also worn shoes and or drums will allow the cam to pivot too much and it can't return for the same reason.

All possibilities have been mentioned above. All I can ad is... You may get lucky and find that a good clean and light lubrication of the cam will cure the issue. Where the cam passed through the back plate there are seals, may be worth replacing them while you digging into it. Use waterproof grease on the cam where it passed through the back plate and anti-seize (copper grease) on any moving part within the brake assembly. Obviously not on the friction material or brake drum though lol

i used permatex anti-sieze. didnt last as long as i though it would. too many water leaks i guess. still is the best for a breach plug or nipple, on a muzzle loader.
not to mention, exhaust connections... and spark plug threads.. Anti-seize copper grease, i got to look up...
