Air discharge of brake system
Remarks:
It should discharge the air if operate on the brake system or as-
sume the brake system pipeline has the air.
Caution:
Must not keep the brake fluid on the paint surface, wipe off it if
has.
1. Fill the liquid reservoir up with the brake fluid.
Check the liquid level in liquid reservoir after discharge the air of each
wheel pump. Filled with the brake fluid if necessary.
2. Connect the polyethylene resin pipe to the overflow hole plug of
wheel pump;insert the other end of pipe into the container with
half of brake fluid.
Remarks:
When discharge the air of wheel brake pump, it should begin
from the longest pipeline.
3. Air discharge of brake system pipe
a. Step down the brake pedal slowly for several times.
b. Let the assistant presses down the pedal, at the same time screw
off the overflow hole plug until the brake fluid flows out. Then
switch off the overflow hole plug.
c. Repeat the procedure until the liquid is without air bubble.
Tightening torque of overflow hole plug: 11N
m
4. Process the same procedure for each wheel pump.

Replacement of brake block
Remarks:
When brake during the travel process, if the front wheel has the
continuous screams noise, then it should check the wear limitation
alarm plate of brake block. If the alarm plate has the abrasion
mark with brake disc, then it should replace the brake block .
1. Remove the front wheel
2. Check the thickness of abrasion material of brake block.
Check the thickness of abrasion material of brake block by the watch
hole on the tong.
Replace it if is not within specified range.

Replacement of brake block
Remarks: if the rear wheel generates the cheep during the braking,
it should check the abrasion indication plate of brake block. If the
indication plate has the abrasion mark with brake disc, then it
should replace the brake block .
1. Remove the rear wheel
2. Check the thickness of brake block bush.
Measure the thickness of the brake block bush (abrasion material)
from the eyehole of tong. If the thickness is not within the specified
range, then it should replace the brake block.
minimum thickness: 2.0mm.

10. Adjust the clearance between the brake drum and brake shoe.
Poke the adjusting hole plug on the brake drum, insert the screwdriver
into the clearance-adjusting hole; rotate the clearance-adjusting gear
to expand the brake shoe until the brake disc can not be rotated by
hand. Then rotate it for 3-5 teeth in anticlockwise, rotate the brake
disc by hand at the same time, it is proper that it can rotate freely
and without the contact between the abrasion and disc. It is allowable
that the non-running-in brake shoe has the slight abrasion sensing.
When adjust the clearance, the left and right wheel must be adjust at
the same, install the adjusting hole plug after the completion of
adjusting .

Technical requirements
1.The fastening torque of the mounting bolts of the integral power
steering gear assembly is
2.The fastening torque of the connecting bolts of the steering drive sub-
assembly and the integral power steering gear assembly is
3. The fastening torque of the connecting bolts of the steering drive
assembly and the left horizontal beam of the frame is
4. The fastening torque of the mounting bolts of the power steering
pump is 40N.m.
5. The tension force of multi-wedge belt 4PK1100 is 4PK1100.
6. Centering fastening of the handwheel: steer the front wheel to the
right front and remove the handwheel without changing the position
of the steering stem, install the handwheel aligning the center, the
radials of the handwheel should be at the left & right centering state;
the symbol of “the Great Wall” on the steering wheel shall be in
driver’s straight view position, secure the nut firmly with the
fastening torque of
7. Inspection of free clearance of the handwheel
Steer the car in a straight direction and stop the engine, apply a 5N force to
the handwheel along the circumference, left turn the handwheel and stop
the turning when the resistance is increasingly felt with each turn; then right
turn the handwheel and stop the turning when the resistance is increasingly
felt with each turn; the angle rotated along the circumference is the free
clearance of the handwheel, whose standard value shall be below 20
, and
the angle from the center to the right shall not be more than 10
