What is this "break" that hits the helmet? What gets broken?

I think it's wise to use the power switch for routine shut off. E-brake had
some kind of pad or lining that won't last forever.

The break often hits the helmet of the sawer. Sometimes it is brush.

I use the off switch on mine. The brake I save for dangerous times.
