Hada similar prob when my bike was new. The rear brake leaver would stick and actually touch the fairing when it would budge! Hackett's said they all do that. So i spent a year with no back brake! You kinda get used to only the front one. Decided to bleed it myself, and now i have a back brake!!!! feels odd to not roll back on an incline! kinda miss it not working, tends to focus the mind.
