And manual parking brakes aren't really wonders of mechanical simplicity anyway

The real magic/genius are trailer brakes, they are electric right, however if they worked the way you would naively assume an electric brake would work, directly operating on the friction surface with an electric solenoid, It would take a huge solenoid and the amperage requirements would quickly exceed what the trailer wiring can provide. so what they do is apply an electromagnet which starts to drag on the side of rotating wheel assembly it uses this drag to push the friction surfaces together, so it takes a surprisingly small magnet to run. most of the force comes from the rotating wheel.

That's the "self-applying" property of drum brakes. Not specific to trailer brakes.

They're actually really simple? Two wedge-shaped brake shoes that cam into the inner diameter of the wheel.

More not easy to servicd if they seized and you can disassemble half the car to get to all the cables and so on

You can almost always pop the cable (if you have to) and hit the rotor with a hammer, or use a puller.

If that doesn't work you hit it with a hammer from the other side until the parking brake shoes pop out of the pins and come off with the rotor.

Hawaii would even have mountaineous and that island climate that's good for growing coffee. But labor costs probably mean they couldn't compete even if they tried

Animal fats are just as well used (or were used, before oil) for lubrication. Most notably probably whale blubber

Yeah, connected a pair to a 2011 phone with Android 2.x (Gingerbread or something along those lines) just fine. Sound quality was even pretty good to my ears, whatever that bluetooth standard could push through the air

Maybe also control for cultural similarity, but I definitely agree

Weary and wary are also homophones, in certain dialects at least

Android profiles with just the the pager stuff installed/enabled would probably work?

And a long/annoying password for the "main" profile, with banking and all the other stuff maybe

Is not being allowed to have children with close relatives also eugenics?

They also don't get it tattoed on their forehead against their will.

At first I thought it was gonna be Babiš. Thank god not
