I will pick one of those up once I can use it, both the clutch and front brake bleed screws have broken off, the clutch one then broke an easy out. So I am not messing with either again until I have new slave or caliper in hand so I dont end up with a bike I can't ride. I don't think either had been loosened in many years from the dark crud that came out of both systems. The rear brake bleed screw actually loosened fine, but that system is horizontal and the syringe isnt as helpful there I dont think.
All of the systems have fresh DOT 4 in them and they are air free now, so I do not intend to mess with them again for a while honestly.
