How to Use This Manual
1. There is a content index on the first page of each
chapter. You can consult the index to see the items
needed for maintenance. In order to make searching
more convenient, the subject of each chapter has been
printed on the page header of each odd page.
2. There is a summary or caution item in the beginning of
each chapter. Please read this content carefully before
any maintenance is performed. Some systems include
a malfunction diagnostic table to help determine ve-
hicle failures and their causes.
3. Throughout the entire manual, each maintenance
step's corresponding specification is highlighted in bold,
so there should be no need to pause maintenance
work in order to find these specifications.
4. Warnings, Cautions & Notes
• Warnings are highlighted in bold, indicating the possibility
of causing injury to oneself or to others.
• Cautions are highlighted in bold, indicating the possibility
of damaging the part being repaired.
• Notes are listed separately from the instructions, not high-
lighted in bold. They are mainly used for additional expla-
nations in order to work more effectively.
5. Maintenance procedures:
Most of the maintenance procedures begin with a high-level
component schematic, which indicates individual vehicle
components and how they are assembled.

The front/rear brakes are disc and drum brakes respectively. The front brake
uses a ventilated disc, and the brake pedal is a suspended pedal with vacuum
booster. Brake line is in a dual-circuit diagonal (X type) arrangement,
adopting a ABS + EBD anti-lock and braking force distribution system.
Service brake booster
and master cylinder
Single stage Φ9inch vacuum booster, series dual-chamber brake master
cylinder, cylinder bore Φ22.22 mm, stroke 32 mm
Brake reservoirShares with the clutch master cylinder reservoir and installed with a brake
fluid level alarm.
Brake pedal strokeFree play: 6-9 mm, working stroke: 37-40 mm.
Brake pedal pressure<380 N (no load) <480 N (full load)
Parking brake
The parking brake system uses a mechanical remote ratchet cable control
mechanism to control the rear wheel drum brake. Brake lever's functional
stroke is 5-8 gearteeth.

Steering knuckle assembly removal
1. Preparation
First, remove the front wheel, the front shock absorber with
coil spring assembly, and the steering knuckle coupling
bolt in turn. For detailed steps, please refer to the removal
of the wheel and the front shock absorber with coil spring
assembly.
2. Remove propeller shaft nuts
(a) First, pry the flattened areas of the propeller shaft's nuts
into a circle with a chisel.
(b) Half-insert a long bolt or metal bar into the brake disc
holes to loosen the nuts (shown on the left).
Tightening torque: 225±20 N·m
Front Suspension
Components
(c) Pull out the mount point on the steering knuckle to
separate it from the mounting bracket under the front
shock absorber. Prop a wood stick or metal bar against
the propeller shaft's outer end, and then hammer the
stick or metal bar to get the propeller shaft out of the
hub (shown on the left).
Caution: When hammering, prop it up against the shaft
end's location holes (middle recess). Be sure not to
damage the thread.

3. Remove the wheel speed sensor and the brake hose
Remove the wheel speed sensor's mounting bolts with a M10
sleeve to take off the wheel speed sensor. Remove the front
brake hose's mounting bolts with a M18 sleeve, and then
take off the brake hose.
Caution: When removing the brake hose, brake fluid
may flow out, catch the fluid with a container. Also,
b e c a u s e t h e b r a k e f l u i d i s c o r r o s i v e , p l e a s e p a y
attention to personal protection.
4. Remove the cotter pins and lock nuts of the steering tie
rod and the lower swing arm
Because the ball stud and steering knuckle act in conjunction
with the tapered bore, they can not yet be removed after re-
moving the nuts. Pound the steering knuckle arm (unfinished
surface) with a hammer. Positions are shown on the left.
Shake to loosen.
Caution:
1. To avoid separating the ball studs, do not pound the
tie rod and the lower swing arm with a hammer.
2. To avoid damaging the thread, do not hammer the
ball stud's head.

Front shock absorber with coil spring assembly (Image)
Front shock absorber with coil spring assem-
bly removal and installation
1. Hoist up the vehicle so that the front suspension is in a
free suspension state.
2. Remove the wheel speed sensor and the brake hose.
Remove the wheels and take out the brake hose from the
shock absorber bracket. Then remove the wheel speed sensor
wire harness (shown on the left) from the steering knuckle.
3. Remove the coupling bolt between the front shock
absorber and steering knuckle and the brake hub
assembly.
Tightening torque: 132±10 N·m
4. Loosen the mounting nuts of the front shock absorber
and remove the front shock absorber with coil spring
assembly (shown on the left).
Tightening torque: 40±5 N·m
5. Installation of the front shock absorber with coil spring
assembly.
Installation follows the reverse order of removal, but
please pay attention to the areas of importance below:
(a) The Insertion direction of the bolts should be consistent
with direction shown in the image. Insertion order is
from up to down. After inserting, tighten them one by
one as required.
