with any wrest for hose.
2． Fix  brake  pipe  onto  brake  hose
with fingers.
3． Install fixed card onto the hose
connector.
4． Fix  brake  pipe  onto  the  brake
hose.

5、Hydraulic brakiing system

exhaust

Warning：Don’t move vehicle before
the pedal is not stable. The air in
the system will cause brake faulty or
personal hurt.
Warning：Only use clean OPEL DOT 4

fluid in sealed container. Don’t use
polluted fluid, otherwise it will
cause damage to parts, bad brake or
personal hurt.
Warning：Don’t fill fluid to much.
It will flow out to engine exhaust
parts to result fire.
HINT: If air enters into brake system
during repairing, carry out complete
draining out air process.
HINT: Avoid spraying the fluid on
paint surface, wires and connectors.
Rinse the parts if any fluid sprayed
on vehicle.
HINT: Strictly observe the process of
draining air. When air enters into
hydraulic  system,  four  hydraulic
systems must be drained. If the hose
or  brake  opens  on  one  wheel,  only
drain out air for this wheel. If the
hose opens in any connector between
master cylinder and the brake, only
drain out air related system.

1)Pressure exhaust
HINT: For vehicle with ABS, apply ABS
automatic darining out air process.
Check if ABS is normal before
draining out.
1.  Check the level of fluid and fill
fluid to correct level if necessary.
2. Remove reservoir cover.
3. Use connector 1 to connect
draining unit with the reservoir.
4. Apply pressure on system.
5. Wait for 5 minutes. Then check
whole system to make sure no any
leakage. If any leakage happens,
service at once.
Attention：Clear the fluid flown out.

6.  Slowly  open  one  of  brake  pipe
connector on ABS regulator to flow
out the fluid.
7. When no bubbles appear in the fluid,
close  brake  pipe  connector  on  ABS
regulator.
Fixture
Screw  brake  pipe  connector  on  ABS
regulator to 8N.m.
8. For other connector, repeat step
6 and step 7.
9. Support and lift vehicle.

10． Remove right rear brake exhaust
valve cover. Put transparent hose to
the valve.
11. Put one end of hose into the
container with clear brake fluid.
12. Slowly open the valve to flow out
fluid.
13. Close the valve when no bubbles
appear.
14. Fix the valve to ６N.m.
15. Remove the transparent hose from
the valve.
16. Repeat above steps for left rear
brake, right front clamp and left
front clamp until no any bubbles
appear.

Points of attention:
Make sure no any leaks for the valve.
17. Remove the transparent plastic
hose from valve.
18. Lower vehicle.
19. Note the pressure remaining in
reservoir when remove exhaust units.
20. Check and fill fluid to suitable
level in reservoir.
21. Install reservoir cover.
22. Start engine and run at least 10
s.
23. Turn off ignition switch.

24. Check brake pedal vibration and
stroke.

If brake pedal is felt stable and

the stroke does not exceed
specified value, go to step 25.

If brake pedal is felt soft and

the stroke exceeds specified
value, don’t drive vehicle and
go to step 26.

25. Start engine and check the pedal.

If the pedal is felt stable, go to

step 27.

If the pedal is felt soft, don’t

drive vehicle and got to step 26
again.

26. Make sure that the bad feeling of
the pedal and the bad stroke are not
caused by bad adjusting for friction
line or other mechanical malfunction.
Repeat draining out air process for
brake system and go to step 1 again.
Warning: Don’t move vehicle before
the  brake  pedal  is  not  stable.
Otherwise it will cause accident or
personal hurt.
27. Test vehicle on road at middle
speed to brake vehicle (without ABS)
