4. If clearance is less than 60mm (2.36 in.), the most
possible cause is either rear drum brake shoes are
worn out beyond the specification value or air is in
lines. Clearance still remains less than 60mm (2.36
in.) even after replacement of brake shoes and bleed-
ing of the brake system, other possible but infrequent
cause is malfunction of rear drum brake shoe adjust-
ers or booster push rod length out of adjustment.
5. Automatic clearance adjuster check is performed af-
ter removing brake drums. If the faulty is found, repair
or replace it.
