Are you talking about the the things that make noise when it’s time for new brakes? One style, for example, is just a flat piece of sheet metal, about a half inch wide, formed in such a way that the edge drags on the brake rotor when the pad is worn down enough. [You can see one here](https://e.ridersdiscount.com/generated/965/1/72965-na-cycle-visions-squealer-brake-pads-rear-for-harley-big-twin-xl_500.jpg). As for why they make noise and the pads don’t, it’s because they’re designed to vibrate at a high frequency when in contact with a moving rotor and brake pads are designed to operate as quietly as possible. Plus, it’s like the difference between moving to flat things against each other vs dragging a fork across a plate.

There’s other ways it’s done as well, but that’s the basic idea.
