The rear brakes can give you a false clearance with the hand brake cable
partially applying prssure on the shoes. Release the hand brake clevis pin
from the bellcrank actuator to allow the rods and levers to let the shoes to
fully come to rest, then adjust the rear show clearance so they are just
skimming the drums, then finally reinstall the hand brake clevis pin and
adjust it for amount of slackness required.
