Sorry, first time dealing with road caliper brakes (only dealt with disc and v-brakes before).

In the pic below, is the serrated washer already on the brake (Blue arrow) for shimano/sram and the serrated one on the carpet (Green arrow) for Campy systems? I use one or the other right?

Wouldn't the serrated washer dig into the brake bridge and the carbon fork if tighten? Is that bad? Or is that the way to grip and make sure the install is secure? Or do I need another type of washer or rubber/plastic ring/washer? Thanks!
