Before you install the drums check to see that the star wheel adjusters are working and take note of which way to turn each one to move the shoes closer to the drum. Install the drums and adjust each shoe as you spin the wheel until you feel it grab the drum. Then back off a click or two. Have someone squeeze and hold the brake lever while you slowlyopen the bleed screw and let the fluid and air escape. Tighten the bleed screw before you release the brake lever. Keep repeating this on both sides until there are no air bubbles coming from the bleeders. Make sure to keep the master cylinder on the handlebars full of fresh brake fluid as you do this to avoid getting even more air in the system. Recheck the shoe adjustment.
