Another way for adjustment, and to test the shaft is going all the way into the M/C, is to remove the brake lever and reinstall, anti clockwise, say from 3o'clock to 1.30.
Also need to disconnect the caliper and have it lower than the swing-arm and get the bend out of the brake line for a continuous uphill gradient to the reservoir .........Don't forget to put a 5-6mm spacer between the caliper brake pads.
If our not still getting fluid through the bleed screw , make sure the screw is cracked enough for flow or remove it and check for a blockage. If non turn the caliper upside down, without the bleed screw and try again..........use a tray or better still an empty 4 liter oil container with the side cut out...........i use them for all my oil changes and such..........
