Modern Vespa

My front brake on my 2020 HPE Supertech has gone soft over the winter rest up even after the brake recall the previous year,so it requires a full flush.
So ive decided to have a crack at doing it myself and i have by chance brake bleeding kit in a cupboard sat unused.
After watching Robots YT video he says that the ABS may be affected so im wondering if its a straight forward enough job.

Has anyone done it and is it a straight forward enough job for someone like myself with a reasonable amount of mechanical competency to undertake.

Any advice would be appreciated.

If it's just bleeding needing doing it won't have to be a full flush. I can't comment on the ABS issue tho'. But my top tip having done it myself on other scoots is to check you can actually loosen the bleed nipple before you start in earnest. And give it all a good clean before even that stage!

being its 4 years old a full flush would be recommended unless it was done last year.

some folks like to use a vacuum bleed tool like a mighty vac. other like using the old method of firm brake pressure keeping the pressure on then slightly opening the bleed nipple and slowly keep squeezing the lever till just before it touches the handle bars and then tightening the nipple . doing this method require multiple times doing it. remember in-between each pull to top off the fluid as you NEVER want that fluid to drain completely out of the master cylinder as you WILL get air bubbles in the lines. Those a a bitch to get out some times.

Yes and yes. It's not a job to underestimate as it has some pitfalls (see OAD's comment), but if you follow directions, it's not hard.

Full disclosure: I don't have an HPE. Is it safe to assume that it's not different from other ABS models?

Devices like Mighty Vac or old school pump and hold work fine. There use to be rumors that the ABS resiovor needs to be flushed too, and I know of some car systems that this is true, but I have bled many many automobile and motorcycle ABS systems without bleeding the ABS module without any issues...

Speaking of bleeding versus full flush, does Piaggio have a recommendation? I don't see a differentiation in their maintenance schedule.

The two are synonymous. it makes no sense to open the reservoir to top off only to bleed. Drain the reservoir with a turkey baster or syringe, fill and bleed. When you see clear fluid coming out your bleeder line, and no more bubbles, you are done.
