    You may need to knock out the holes to get to the adjusters. They are at the bottom of the backing plate. About a quarter inch high, inch wide. There are two.

    You should be able to adjust them most of the way before you put the drums on and do the finishing touch through the knockouts. If that doesn't work I would bleed the rears again.

    Adjusters are accessable through rubber knockouts on the back of the drum. A screw driver or brake spoon can adjust them but you can also adjust them by driving in reverse for a few and hitting the brakes.

    I advise taking the drum off and doing a once or twice over everything though.
