Coaster Hub Brake Arm
I am using a rear coaster brake hub on a singlespeed I recently restored and I was wondering what exactly is the function of the brake arm?
Like, I can't understand how this thing could actually do anything, but according to Park it is absolutely necessary that it be bolted down.
Could I just leave it off? Or just not bolt it down? Or is that a big no-no when it comes to coaster brakes?

When the brake stops the wheel from turning, it's what transmits the torque to the frame.
If you left it off, all the force of stopping a wheel would go into the frame through the hub. It would probably not have enough friction and would twist until you loosened the right hand nut and the axle broke.
