2) Depress brake pedal a few times.
3) With brake pedal depressed with approximately 30kg (66 lbs)
load, measure brake pedal to wall clearance "a".
Clearance "a": Over 165 mm (6.50 in.)
4) If clearance "a" is less than specification, the most possible
cause is either rear brake shoes are worn out beyond limit or air
is in lines.
Should clearance "a" remain less than specification even after
replacement of brake shoes and bleeding of system, other pos-
sible but infrequent causes are malfunction or misadjusted of
rear brake shoe adjusters or booster push rod length out of ad-
justment.
