If it's just from flipping the bike over, then yeah you have air in your reservoir.Right, but wasn't the problem described as flipping the bike over? Air pressure does not change by flipping a bike over. Its a closed system and shouldn't allow air or fluid out. If you force fluid/air in/out then that's a whole different issue. I think the best way to bleed the brakes is to bleed them, flip the bike, hit the lever, flip the bike back over and re-bleed (hey just my style... heh) g'luck (and I love my codes, 1 bleed since purchase last season)
I love my Saints even more. 0 bleeds since ever.
