Tonight I decided to change the fluid in my Hebo unit because I noticed some muck inside the slave cylinder (I hope that doesn't mean I have a leak). Anyway I pulled the unit apart and cleaned everything good. When it came time to put new fluid back into the master that's where the confusion set in. I relied on the old "pump and bleed" technique but after twenty minutes it got really old when nothing happend. I thought it would be just like a car but im dumbfounded why I couldn't get it right. It seems as though no fluid is getting down to the slave cyliner and I have no clutch, Any advice???
