The way I always have bleed brakes is the two people reqd method... Empty out old dirty brake fluid from header (old bulb hydrometer for testing battery acid) and fill with clean fluid. setup.. clear pipe from nipple into clean glass jar with a little fluid in to view bubbles etc. 1/ check fluid level 2/ open valve, 3/ gently press pedal to floor and HOLD 4/ close valve 5/ release pedal repeat until clean fluid AND no bubbles THEN on last pressing of pedal, close valve whilst being pressed. If you apply pressure first, air tends to get pressed in the wrong direction at Y's etc and you never get rid of it. NEVER recycle brake fluid, it absorbs water and should be changed every two years, old 'wet' fluid boils at a lower temperature than new fluid - if your brakes boil on a long descent, you don't have any brakes.
