4. Observe the height of brake liquid level and, if
necessary, add in the brake liquid and exhaust the air
in braking system.
Notice: prevent the brake liquid from spraying on the
brake disc when exhausting air.

2. Measure the thickness of brake disc;
Standard thickness
20.0mm
Min thickness
18.0mm
If the brake pad is scraped, repair it; where the abrasion is
serious and its thickness is smaller than the min thickness,
change the brake disc.
3. Measure the bounding value of the brake disc face;
Remark: the bearing is required to be verified in the suitable
adjustment before measuring.
Max face bouncing value: 0.11mm;
4. Change the brake disc according to the requirement:
(a) Tear down the hub and the brake disc. (see the paragraph
of front wheel hub)
(b) Mount the new brake disc and screw up the connecting
bolts as the specified torque.
(c) Mount the hub and brake disc assembly. (see the para-
graph of front wheel hub).

1. Tear down the rear wheel;
2. Tear down the brake drum;
Remark: in case the brake drum is not easy to tear down, the
following steps shall be adapted:
(a) Tear down the clearance-adjusting hole; insert a screw-
driver in the brake bottom plate hole to prize up the
adjusting bolt inner tilt angle with the self-adjusting fork.
(b) Use another screwdriver to adjust the adjusting bolt inner
tilt angle to loosen the clearance adjuster of brake shoe. DrBraking System

Gearbox
Three-grade maintenance for gearbox
1. Grade I maintenance for gear box
Grade I maintenance: Check the lubricant level to see whether the lubricant level is in alignment with the lower edge of oil
filler; if the lubricant is lower than the oil filler lower edge, add the lubricant; or the insufficient lubricant will lead to the poor
lubrication or burn-out of bearing and teeth; while the over-high lubricant will cause the overheating and oil leakage.
2. Grade II maintenance for gear box
Grade II maintenance: The gear box of a new vehicle should be maintained by exchanging the lubricant during the
first grade II maintenance and should be washed with kerosene; and the lubricant quality should be checked in the
grade II maintenance in later time, if the lubricant is diluted, gumming or over-dirty, it should be changed.
3. Grade III maintenance
The gearbox should be disassembled for inspection, washing and oil change.
Notice: As the new vehicle is in the running-in status, the gearbox should be maintained by exchanging lubricant
after the vehicle covers 1500 km,
