Modern Vespa

Hey all, I basically think I have either a bad switch like I have read or my hydraulic fluid maybe is dirty. It is just a little bit above the below or minimum line and I'm not quite understanding how to bleed the lines. Can I just take some kind of a suction and suck out the reservoir and add newluid instead of trying to bleed everything, I want to try this first to see if it will get rid of that dreaded five horn honk before I tackle anything else meaning the switch. Thanks .

Take a syringe with a pipe and push the fresh fluid into the bleeders down there. Quite easy task in fact.
