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.

Transmission's Proper Use and Care
1. Transmission's proper operation
1.1 Shift the gear gently, not excessively.
1.2 Do not start with high speed.
1.3 To avoid premature abrasion of the gear shift fork, do not rest your hand on the \
gear lever while driving.
2. Model number of the lubricant to be used:
GL-4 80W-90 (For China domestic model)
GL-4 75W-90 (For alpine region model)
GL-5 140 (For high-temperature region model)
Caution: Please only use the lubricant with model numbers specified by t\
he Great Wall Motor Co., Ltd.
Do not mix lubricants with different model numbers. Only fill with clean lubricant.
3. Areas of importance for new vehicle usage:
3.1 Before using a new vehicle, be sure to check the transmission and all exposed connectors and fastening
pieces, so as to avoid failure due to faulty installation or loose conne\
ctions.
3.2 Since the new vehicle is still in the run-in period, the transmission's lubricant should be replaced after 5000 km
distance.
4. Transmission three-level maintenance:
4.1 Transmission level-one maintenance: During the first level of maintenance, the liquid level of the lubricant
should be checked to ensure that it is up to the oil-filling mouth. Add more if insufficient. Excessive low
oil level can lead to ineffective lubrication, as well as burning of the bearings and gears. Excessive high oil
level, however, can overheat the transmission or cause oil to leak. In addition, during the first level of main-
tenance, the breather plug should be checked and cleaned. If the breather plug is clogged, internal pressure
will build up and oil will leak from the transmission.
4.2 Transmission level-two maintenance: The transmission's lubricant should be replaced the first time that the
vehicle undergoes the second level of maintenance. Clean the transmission with kerosene. The quality of the
lubricant should be inspected during the future second level of maintenance practises. The lubricant should
be replaced if diluted, gummy, or dirty.
4.3 Transmission level-three maintenance: During the third level of maintenance, it should be removed for in-
spection, cleaning, and oil changing.
