9.2 Air discharge sequence of brake system is:
Left back right front right back left front. If the ABS system connects with
failure diagnosis instrument, you can access the fluid filling and air release program, and
discharge the air from the ABS system according to the steps prompted by the system.
9.3 Air discharge of brake loop
Connect the exhaust hose of container to the fluid and air discharge valve of the left-back
brake caliper. Open the fluid and air discharge valve, and step on the brake pedal to the earth
for at least 5 times. The discharged brake fluid must be clean and have no air bubble. Keep
stepping on the brake pedal to the largest extent, close the fluid and air discharge valve and
then loosen brake pedal. Similar operations can be applicable for the brake systems of other
wheels.
9.4 Brake fluid filling
In order to ensure the reliability of brake system, you should check the brake fluid level at
intervals or after finishing the air discharge of the brake system. If brake fluid is deficient,
you should fill it instantly.
Note:
(1) Brake fluid should meet the standards stipulated by the Department of Transportation
(DOT) (only DOT4 can be used), and should not be mixed with other types of brake
fluid.
(2) Brake fluid has relatively strong water absorptivity. It should be put into the original
sealed container when being recycled.
(3) Brake fluid has relatively strong corrosiveness. If it splashes onto your skin, you should
instantly use wet cleaning cloth to wipe off the brake fluid, and then wash your skin by
soapy water. Brake fluid is strongly corrosive to the car body paint; therefore, you
should prevent the brake fluid from splashing onto the car body paint. If the brake fluid
splashes onto the car body paint, you should wash it immediately.
(4) During the process of air discharge, you should pay more attention to the brake fluid
level of fluid reservoir. If the brake fluid level is very low, you should refill it in time.
(5) Manual air discharge operation should be repeated for more times until the air in the
brake system is completely discharged.
(6) After finishing the fluid filling and air discharge operation, you should check whether
there is leakage in the brake system. If leakage phenomenon exits, you should eliminate
it timely in order to ensure the safety of car driving.
