Thank you mark. I'm probably allowing it to suck air. I didn't have any help so I was depressing the brake with a 30# sack of fertilizer then I clamped the plastic bleeder lines in the prongs of a fork. kind of how you would shut an IV line off. Then I would remove the sack and start over. This got very tiring. please don't laugh. If you notice in the instructions above you hold your finger over the port while "you depress the pedal". Only a large octupus could do this. its 2 persons.
