per my experience (I work in a motorbike rental company since Year 1995, we have now about 40 Piaggio vehicles) everything is possible.
Brake lights switches broke down often, for corrosion, dirty, lever crashes, ...
Once you have checked the brake light, if it switches on braking, it means that the switches are ok; if not, check the switches. It's easy and takes a short time.
What about the starter relay?
