old trick for new dogs
drain the fluid by the quickest way (doesn't matter how)
add new fluid to the system and push fluid into the bleeder using a sealed plastic bottle with a hose sealed through the lid (hose through smaller hole). squeeze the bottle forcing fluid into the system.
99.9% air from system now, lever feel pretty good.
enter old trick... ahwooooo ahwooooo (polite applause)
pull the lever back to the bars with a cable tie or similar and leave over-night. this will allow any remaining air to self bleed from the system making the lever feel superior to normal.
Thank you, thank you...no, you're too modest.
