7. Install the brake cable connector on the brake trailing
shoe with brake lever assembly.
(a) Install the brake cable connector on the brake trailing
shoe with brake lever assembly.
(b) Insert the brake trailing shoe with brake lever assembly
and the shoe end of the brake leading shoe assembly
into the wheel cylinder assembly.
Remark: Do not let oil or grease drip on the brake shoe's
lining.
8. Install the retainer spring.
9. Install the brake leading and trailing shoe assemblies
onto the brake back plate assembly.
(a) Insert the pressure spring bar into the brake back plate
assembly and brake leading and trailing shoe assemblies.
(b) Put the pressure spring on the pressure spring bar,
put in the pressure spring cap, and use SST (Special
Service Tools) to lock the pressure spring cap onto the
pressure spring bar.
10. Inspect the operating procedures of the automatic ad-
juster.
(a) Refer to the diagram for directions, step on and off the
brake pedal, and make sure the self-adjusting screws
can rotate. If they are unable to rotate, inspect the rear
brake to try to determine the source of the problem.
(b) Adjust the adjusting mechanisms length and make it as
short as possible.
(c) Install the rear brake drum.
(d) Press the brake pedal towards the floor until a clicking
noise cannot be heard.
11. Inspect the space between the brake's friction plate
and rear brake drum.
(a) Remove the rear brake drum.
(b) Measure the rear brake drum's internal diameter and
the brake shoe friction plate's external diameter, and
inspect if the difference between the two diameters is
within the regulated clearance range.
Single sided clearance: 0.25 mm
If not correct, inspect the braking system.
12. Install the rear wheel.
Tightening torque: 100 N·m
13. Fill the brake fluid reservoir up with brake fluid and
exhaust the air out of the brake system.
14. Check for leaking brake fluid

Rear hub unit inspection and removal
1. Manually rotate the wheel according to the diagram,
and check the bearing of the rear hub unit for abnormal
noises and stiff rotation. If these flaws exist, please
replace the rear hub unit.
2. Remove the wheel.
3. Manually screw the two wheel nut's opposite angles on the
wheel bolt and fixed rear brake drum.
Remark: Alternately tighten the two nuts, and manually
screw it down as much as possible.

4. Measure the rear brake drum's outer end surface
runout.

mounting bracket. Point the dial indicator to the rear brake
drum's outer end surface diameter at about a Φ136 mm
circumference (refer to diagrams dotted line area). Rotate the
rear brake drum, measure its runout, and maximum runout
0.11 mm is approval.
Caution: When the runout exceeds the maximum limit
of 0.11 mm, the rear hub unit should be replaced.
5. Remove the rear brake drum (See rear brake removal
step 4).
6. Examine the rear hub unit's starting torque.
(a) M a n u a l l y r o t a t e t h e r e a r h u b u n i t a n d c h e c k f o r
abnormal sounds or looseness. If the above problems
exist, it should be replaced with a new rear hub unit.
(b) Use a spring dynamometer to inspect the load applica-
tion.
Load application (when start the engine): 1 N·m
Caution: If the load application is greater than 1 N·m,
the rear wheel hub unit must be replaced.
7. Use calipers to measure the rear brake drum's internal
diameter.
If the measured result exceeds 201 mm, the drum brake must
be replaced.
Trailing arm spindle sleeve assembly removal
1. Examine the trailing arm spindle sleeve.
(a) Inspect the trailing arm spindle sleeve for deformities,
shifting, partial or serious cracks, and the gaskets for
loosening.
(b) If it's not easy to see clearly any existing damage of
the trailing arm spindle sleeve, take the following
steps: Use clean water to wash the trailing arm spindle
sleeve's rubber areas. At the same time rub it clean with
cotton. Check and make sure the rubber surface has
none of the previously mentioned flaws. If the above
flaws exist, replace with a the new trailing arm spindle
sleeve assembly.Cotton

2. Remove the trailing arm spindle sleeve.
(a) M a r k w i t h a w h i t e p a i n t p e n , a n d r e m e m b e r t h e
direction of the trailing arm spindle sleeve assembly .
(b) The trailing arm spindle sleeve is a disposable part. If
it is damaged, first use a pry bar to lift up the edge of
the trailing arm spindle sleeve's outer tube in order to
install SST.
(c) Use SST (Special Service Tools) to clog the spindle
sleeve's installation tube. Tighten the two bolts, twist
them with a wrench and push out the spindle sleeve.
Caution: When performing the pressing out process,
be certain to ensure the trailing arm spindle sleeve is
vertically forced out.
3. Install the new trailing arm spindle sleeve with nylon
bushing assembly.
(a) Before installing the new trailing arm spindle sleeve
with nylon bushing assembly, first distinguish the
installation direction for the trailing arm spindle
sleeve's nylon bushing assembly, whereas the direction
of the nylon lining's four holes face one end of the
trailing arm.
Caution: Do not install the trailing arm spindle sleeve
with nylon bushing assembly in the opposite direction.
(b) Use SST to position the trailing arm spindle sleeve with
nylon bushing assembly, and slowly press it in.
Caution: When performing the pressing process, be
certain to ensure the trailing arm spindle sleeve is
vertically forced in.

Steering System Maintenance
Structure Introduction
The steering wheel has an airbag module which should only be inspected and repaired by a professional. The
steering column's upper section adopts a steel deformation and energy absorbing crumple structure which
ensures collision protection for the driver. The lower section uses a high precision sliding spline structure,
which can effectively eliminate structural interference caused by body deformation. The steering column angle
is adjustable, which can more easily adapt to the driver, and at the same time possesses reasonable reverse
efficiency to ensure the driver has a good feel for the road. Steering sys\
tem is as shown below:
Steering column assembly removal and
installation
1. Remove the airbag.
(a) Disconnect the battery's negative cable, and wait for
one minute before canceling the airbags function in
order to avoid unnecessary injury.
(b) To ensure steering column's proper installation, during
the entire removal process, the front tires must keep
straight.
(c) Remove the two hexagon screws and the airbag module.
