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

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.

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

mounting bracket: 25±3 N·m
4. After the installation of the power steering pump and
steering pump belt is completed, adjust the tension
of the entire power steering pump belt. Belt tension
should be 450±50 N.
Use an exertion force of 98 N in the middle of the belt.
Belt deflection should be 4-6 mm.
Power Steering Fluid Instructions
Replace the power steering fluid in the following situations:
1. After driving a new vehicle for 6000 km.
2. After replacing any part of the power steering gear, power steering pump and steering pipeline.
3. Driving 6000 km after replacing power steering gear and power steering p\
ump.
Caution:
1. The expelled power steering fluid after replacing power steering compone\
nts cannot be reused.
2. Only use ATF DEXRON III power steering fluid.
3. No matter when the PS fluid reservoir level drops, check the PS fluid reservoir, steering pump, power
steering gear, and steering pipeline, as well as all the connections.
Methods:
Two people are required to add power steering fluid. With the engine off, one person pours the fluid
into the PS fluid reservoir, while the other repeatedly turns the steering wheel from lock to lock for
more than 10 laps, until the steering fluid level is between MAX and MIN. Start the engine and turn
the wheel from lock to lock again (Caution: Do not leave it at the two extreme points for more than 5s).
When the fluid level goes down, refill the steering fluid until it is be\
tween MAX and MIN.
Technical Requirements
1. Mounting bolts with thread fastening glue for the power steering gear, tightening torque is 107±7 N·m
The coupling torque for the steering gear's tie rod and tie rod ball is \
74±7 N·m
The coupling torque for the steering tie rod ball stud and steering knuc\
kle is 49±5 N·m
2. The tightening torque for the steering column assembly and steering gear assembly's secure coupling
bolt is 25±3 N·m
The coupling bolt torque for the steering column and dashboard brace rei\
nforcement is 25±3 N·m
Torque for the fixed steering wheel nut on the upper section of the steer\
ing column is 50±4 N·m
3. Fasten the steering wheel center
Keep the front wheel pointed straight ahead, make sure not to change the direction of the steering rod, and
take down the steering wheel. Install the steering wheel in the center. The steering wheel's radial should be
in the middle, and the Great Wall logo should be in the direct sight of the driver, then tighten nuts.
Tightening torque: 50±5 N·m
4. Steering wheel free clearance inspection
Keep the vehicle centered, stop the engine, and turn the wheel left with a force of about 5 N. If
resistance is felt, stop when the resistance increases. Then turn right and stop under the same
situation. Measure the angle that the steering wheel turns along the outer edge. The angle value
measured is the steering wheel's free clearance. Its standard value should be less than 20°, and from
the middle position it should not turn at a left or right angle larger t\
han 10°.
