when to replace kids coaster brake
Just bought a 16" kids' bike off craigslist and am overhauling it. The bike obviously had a few miles on it. The brake did work, but no one actually rode it as it is my son's first bike so he doesn't know how to ride it yet. It's a surprise for him and there are no training wheels (he's been using a balance bike so hopefully we don't need them).
My question is, how do you know when to replace the coaster brake vs. simply cleaning and regreasing? There is some wear on the brake shoes, but they are not smooth. It seems the parts aren't that expensive at bikepartsusa so should I just go ahead and do it anyway since we'd also like our 2nd son to use this bike eventually? Or is that unnecessary and I should just regrease it?
Thanks.

Older hub, of better quality? or some of the 'make it as cheap as possible' hubs
used in what gets sold as a bike, from discount big box stores?

So long as the lines (opposite of splines) are still clearly defined on the shoes, the brake should continue to function. Once they start to fade, time to replace.
I have a large bin of abandoned parts and hubs. Customers don't want 'em, and I don't consider them mine. I consider them as belonging to anyone who "needs" em.
One part is a complete internals assembly for Kun Teng Coaster Brake hubs (HI-STOP). Probably seen about 1/2 of its usable life. If you want it, it's yours for the cost of shipping.

Given that it's only stopping a small payload, I doubt the brakes can ever wear out. The test is fairly simple. Your child should be able to skid the bike without great effort. If it passes that test, more brake wouldn't stop any better anyway.

It is a hub from a Giant bike and the lines are still visible, so I'll just regrease it. Thanks for the advice and thanks for the spare parts offer mrrabbit!

As for teaching your son to ride, this is the quickest way IMO:
Find a gentle grassy slope, and hold the bike under the seat. Run along holding the bike up, and you'll feel the gyroscopic effect start to hold the bike up for you - and say so at the time.
After doing this a few times, let go at that point. Shouldn't take much more than twenty minutes.
