Caution:
●This inspection should be completed by a qualified
maintenance organization.
●Regularly check whether the brake flui d level is at 3/4 of the
observation window.
●If you accidentally swallow the brake fluid, you should
contact the poison control center or hospital immediately; if
you accidentally get the brake fluid into your eyes, rinse with
water and seek medical attention immediately.
●Brake fluid must be kept away from children and pets.
●It is strictly forbidden to directly flush the main pump with
high-pressure water.
1. Check the brake components
a. Check whether the liquid level of the front disc brake
main pump and the rear disc brake main pump are above the
"LOWER" line. Check whether there is brake fluid leakage at
the oil pipe joints. Observe the color of the brake fluid.
Normally, it should be light yellow. If the color becomes dark,
it is recommended to replace the brake fluid.
b. Park the vehicle on a flat ground or a lifting platform,
and lower the main support. Check whether there is brake
fluid leakage at the oil pipe joints of the main pump, ABS
hydraulic control unit and caliper. The endoscope with LED
can be used to check the oil pipe joints of the ABS hydraulic
control unit and the main pump, or to remove the
corresponding cover for inspection.

c. Measure the thickness of the front and rear brake discs.
If it is less than 4.0mm (0.16 in), replace it. Hang the front
wheel in the air and turn the front wheel by hand to observe
whether there are obvious damages on the surface, such as
pits, deep scratches, grooves, etc. Replace it if necessary. Feel
with your hands whether there is a noticeable sound of
grinding the brake disc when turning the front wheel.
Observe from the front whether the brake disc swings when
turning the front wheel; if there is any swing, please remove
it according to the steps of dismantling the brake disc, and
place it on a standard platform, use a dial indicator to
measure the run out or use a feeler gauge to check the brake
disc and The gap of the standard platform; such as> 0.08mm
(0.003 in), you need to replace the new brake disc. Check the
rear brake disc in the same way.
●Before checking the brake disc operation, be sure to wait
for the brake disc to cool down before proceeding.
●It is forbidden to reduce the temperature of the brake disc
by spraying water, which may cause deformation of the
brake disc and abnormal noise.
●If the brake disc anti -theft lock is used, please confirm
whether it has been removed before driving the vehicle.
●Clean up the silt attached to the brake discs diligently.
d.Use 5# inner hexagon to remove bolt ⑴ . Remove bolt ⑵

wear of the brake pads. If worn or nearly worn to the limit
position, new brake pads must be replaced in pairs.
f. Take out the wheel speed sensor ① from the wire

torque of bolt ⑵ : 24N.m (2.4 kgf.m, 18 lbf.ft). Do not operate
the brake handle after removing the caliper.
g. Pull out the rear caliper assembly and check the wear of
the brake pads. If it is nearly worn or worn to the limit
