Buick & Pontiac
Remove adjusting hole cover. Install a tool through adjusting hole to move self adjuster lever off adjusting screw. Use tool to turn screw and expand brakes until wheel can just be turned by hand. Make sure drag is equal on both wheels. Back off adjusting screw 30 notches. Wheel should not drag after 12 notches. If drag is noticed at this point, check parking brake cable. If brakes still drag lightly after 30 notches, back off 1 or 2 more notches.
