Mysterious. How the hell did that happen in a design 100+ years old?


Yes, I'd have liked some technical detail. Although I realize that's not
the point of the article.

I will say, a three speed with coaster brake is a fairly complicated
bucket of parts. I still don't know what was wrong with the Shimano one
that I had to disassemble multiple times because of its second gear
skipping. It's working now, but I don't feel confident about it.

OTOH, there's not much to the brake part of the device.


Bad grease.

Interesting. We had some 25,000 V circuit breakers that failed to open for
exactly the same reason. Bad grease dried up and prevented certain moving
parts from moving when commanded to do so.

Marketing opportunity! No longer 'permanent lubrication' but
now 'FATAL lubrication'.

These can hardly be called circuit breakers because of the incredible amount of power going through them. They are not build as and electrical mechanism so much as a mechanical one. I could design a better one but they don't pay you to improve a product unless they can make a profit from it.

It's fake news. We all know that the old days were *far* superior to
modern rim/disc brakes.

Honestly, greasing brakes!


Actually the old style single speed coaster brakes did have grease or
oil in them. See

under "Lubrication".

It's brakes and grease, I will never surrender my opinion this is a good
thing[TM]. How do they work?

I think most tractors have wet brakes. Mine does. They seem to work.

Never the less, that is how they were built.

A famous race in the very early days of mountain bikes was called
"Repack" because one trip down Mount Tamalpais and you had to repack
the rear brake.

Wet as in "water" or wet as in "oil"?

They've always, by design, had greased end bearings and
bendix ramps. Classic bronze-on-steel braking or modern
steel-steel pushes the lubricant aside with no issues.

Shimano Roller Brake hubs also need greased brake surfaces.
