Answer 1

Brakes are sometimes better bled in reverse. If you are adding fluid to the master cylinder and pumping it through with the handle or pedal, try doing it in reverse.

Fill your clean oil can with brake fluid and put some plastic hose on it that will fit snug over the bleed nipple. Open the bleed nipple and pump fresh fluid from the bottom up with the oil can. Slow easy strokes, if you aerate the fluid it will form bubbles again in the lines. Capture the excess at the master cylinder but don't re-use it until you have left it overnight for the bubbles to dissipate.
