Iv just bled my brakes on my own in less than 2 minutes with this little bleed tool. I'm sure it's not a new invention but it was to me so may be to someone else on here. It's just a bit of pipe with a 1 way valve on it, stick it on your nipple (ooer mrs) undo half a turn then pump your brake lever a couple of times, do up, job done. Best £2 ever spent.
