Correct vehicle maintenance and repair is very important
to the safety of the maintenance person and the vehicle. If
any vehicle part change is necessary, please use a part with
the same part number or part number specified by the Great
Wall Motor Co., Ltd. Never use a part that has not been au-
thorized by the Great Wall Motor Co., Ltd.
4. Inspect the front brake disc thickness.
Standard thickness: 22.0 mm
Minimum thickness: 20.0 mm
The brake disc must be changed when its thickness falls be-
low the minimum level.
The maintenance procedures are explained step by step:
• The schematics and diagrams illustrate how and where to
operate.
• The titles convey the maintenance content.
• Detailed instruction explains how to perform the maintenance,
as well as introduces other related matters, such as specifications,
warnings, and so on.
For example:

Specifications
Engine Manufacturing Number
The engine manufacturing number is engraved on the left
side of the engine cylinder block.
Vehicle Nameplate
Every vehicle has a vehicle nameplate, and this vehicle's
nameplate is located at the bottom of the right B-pillar.
Identifying Number Location
Vehicle Identification Number (VIN)
A Vehicle Identification Number is a unique serial number
consisting of 17 characters and used to identify individual
motor vehicles. This number is marked at three different
places: at the nameplate, at the upper-left side of the dash-
board, and at the cross member located under the front pas-
senger seat.

Brake
system
Service brake type
The service brake system adopts a hydraulic vacuum power-assisted type.
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.

Areas of Importance
1. Clutch Rigid Pipe Installation
Before installing, check to make sure that the rigid pipe flare contact area is in good condition, the pipeline is
clean, and that there is no foreign materials.
2. Clutch Hose Installation
Check the surface of the clutch hose to make sure that there is no scuffing and that the pipeline is clean.
3. Coat grease on the U-joint of the pedal and the master cylinder.
4. Strictly adhere to the set torque guidelines when tightening the pipe fittings.
Rigid pipe and the master cylinder: M10 16±2 N·m
Clutch rigid pipe and hose: M10 16±2 N·m
5. While the clutch system is undergoing the exhausting process, make sure that all the air bubbles in
the pipeline are cleared out. Then check the brake fluid level in the reservoir, it should be between
MIN and MAX.
Troubleshooting
The numbers in the table represent the order of the possible malfunction causes, so be sure to check each part in
turn. If necessary, replace the part.
