With a hydraulic clutch there's not may options as it's not adjustable like the cable type in other vehicles.
Basics first, I've heard of people installing the clutch slave cylinder or plumbing it upside down, with the bleeder below the hydraulic line. That little bleeder nipple needs to be above the line to ensure all air gets out. You said AX-15 so the slave cylinder should be an external one, not internal, Correct?
Next, it's much easier as a two person job so one can see if there's any air. On my internal slave I went through close to a full pint before all the trapped air got out. Maybe someone here has a better way to bleed the system. Keep the reservoir full because it it sucks air in you'll be back to square one. It's either that or the end connections are still not tight or either the master/slave rubber rings are going bad.
