But why on earth make it a drum? That's a lot of added weight and complexity.
I suspect the answer is that it's because drums are "self energizing". The shoe wedges itself into the drum, so more inertia in the vehicle automatically gives you more braking force. This significantly reduces the effort required to activate them, which is why trailer brakes (which are almost always drums) can stop a 10,000 pound trailer with just a couple of amps at 12 volts coming from the tow vehicle.
Thanks for that. The trailer brake thing is what made it intuitively make sense to me. Disc-brake trailers have big electrically-driven hydraulic pumps with their own battery, whereas drum-brake trailers just have a weenie little electromagnet driven directly from the tow vehicle.
Your right arm is a weenie little electromagnet.

Reason: schpelling
I did brakes on Saturday.
I typically try and get every last penny out of my equipment. But even this was a bit far for me. Guess that's what happens when you're doing 40,000 miles a year and drive like a lunatic.
While searching for "Chernobyl snow globe," I did come across a few things that gave me pause.
Specifically, a number of listings in which people are selling what they claim to be genuine liquidator medals. The awards given, along with 800 rubles, to the tens of thousands of Soviet citizens, mostly draftees, who participated in the cleanup of the accident site, the construction of the sarcophagus, the demolition and burial of contaminated buildings and vehicles, and other such activities.
It makes one stop and consider the story and the life behind each one of these. Many of them were awarded posthumously. And yet here they are, being sold on various internet commerce sites for $30 - $40.
That's a hard thing to really contemplate. It makes me wonder about the person who first sold the item to the obvious middleman-reseller who is now trying to flip it for a quick buck. Were they the original recipient? Their widow or child? What led them to assign such a tiny monetary value to it? No way to ever know.
I wonder about the misspelled word on the globe, was that intentional?
It's hard to call it a mis-spelling, since even "Chernobyl" is a transliteration from Russian.
"Chornobyl" seems to be a common product of native speakers of Ukrainian (which is different from Russian, although it sounds indistinguishable to western ears) translating the name into English. Bearing in mind that Pripyat, and therefore Chernobyl, are located in Ukraine, which even during the Soviet era was a distinct region.

I'm going to guess they are fake copies. Very good copies. I bought this thing back when i was playing Heroes and Generals and it looks perfect when i compare it to pics but yeah it's a fake.
