1.
Inspect the wear condition of brake pad. After the
first 40000km or 24-month driving of the vehicle,
inspect the wear condition of friction linings and
measure the thickness of the most worn part of
brake caliper friction linings with the standard
value of 18mm and limit value of 17mm.When the
thickness of brake lining is lower than the limit
value, the brake lining should be replaced.
2.
In Level III maintenance, the front suspension may
be removed for cleaning of interiors of the steering
knuckle with bushing and wheel hub as well as
bearings. Please tighten bolts and nuts of each
component with specified torques.
3.
Precautions:
The vehicle loading should not exceed the max.
loading weight.

1.
Special measuring apparatuses and tools should be
applied in part inspection. For damaged parts, carry
out maintenance or replacement according to
relevant requirements. In the case of one of the
matching parts is worn and its clearance exceeds the
specified one, please replace this worn part together
with its matching part according to relevant
requirements. Measure the starting torque of the
front wheel hub at wheel bolts, it should be 17 ～
25N.m.
2.
From the point of view of preventive maintenance,
some parts which are still in maintenance or within
wear limit should be replaced before exceeding the
limit.
3.
Carry out appearance inspections of all parts with
specified visual method or red pigment penetration
method. In the case of following abnormalities in
part outside surfaces, carry out maintenance or
replacement
for
relevant
parts
according
to
corresponding
requirements:
Abnormalities
�
Failure or fatigue (in helical spring)
�
Bending deformation (generally in steering
knuckle)
�
Abnormal noise（for bearings）
�
Looseness （in bolts of anti-roll bar and lower
swing arm）
�
Discoloration or seizure（for steering knuckle
ball joint etc.）
�
Rusting
�
Deterioration（for brake lining）
4.
For all rubber parts like oil seals, gaskets,
bushings,etc., they should be replaced with new
ones
after
removal.
For
standard
parts
like
pre-riveted nuts and bolts with rubber, they are not
reusable.
5.
Abnormal sound is a kind of noise, mainly
appearing as abnormal sounds like clash or harsh
screaming,etc. under different service conditions
(like vehicle speed or road
conditions). Some of
these sounds may fade out with running-in while
some may increase gradually due to improper
adjustment in assembling. On condition that the part
is qualified, adjustment of part assembly clearance
may be taken as solution.
