FAQ: Why do my front brakes make a whirring / cricket sound?
All modern Vespas make that noise when the brakes are applied, whether you can hear it or not. The sound is produced by air trapped in the holes in the disc when the brake calipers squeeze the disc. It's perfectly normal.

And yes, the rear disc brake (if so equipped) makes that sound as well, you just can't hear it as well. For that matter, any vehicle with drilled (aka vented) disc brakes will make the very same noise when braking.
