Use the wrench to first turn the
adjusting arm worm shaft to achieve
the full contact of the brake shoe
surface abd brake drum surface, then
turn it loose for 1/2~2/3 circle(at that
time the clearance between the center
of the fricton lining and the brake drum
is about 0.7mm), and the brake drum
hub assembly can turn freely without
any interface to other parts.
The spring brake chamber do not
need maintenance, but examine and
repair once after 2 years using.
Check: The starting pressure of the
diaphragm cylinder is 20~30kPa. If the
pressure rise to 50kPa, you have to
check it. Under the condition of wheel
brake in proper adjustment, the dia-
phram travel should be 1/3 of the possi-
ble total diaphram travel. At this time,
