Brake-13
Check the component of front brake
1. Measure the thickness of the brake block bush.
standard thickness: 9.0mm
minimum thickness: 2.0mm
It should replace the brake block if less than minimum thickness or
has uneven abrasion.
2. Measure the thickness of the brake disc.
standard thickness: 26.0mm
minimum thickness: 24.0mm
It should repair or replace the brake disc if the brake disc is damaged
or worn or its thickness is
less than minimum thickness.
3. Measure the circular runout of the brake disc.
Remarks: It should ensure that the bearing is adjusted correctly
before the measurement . maximum circular runout : 0.11mm
4. Replace the brake disc if necessary.
a. Remove the tong bracket form the steering knuckle.
b. Remove the hub and brake disc. (Refer to section “Front hub”)
c. Install the new brake disc; tighten the connecting bolt to the
specified torque.
Tightening force: 90
100Nm.
d. Install the hub and brake disassembly. (Refer to section “Front
hub”)
e. Install the tong bracket on the steering knuckle; tighten the
connecting bolt to the specified torque.
Tightening torque 140
10Nm.

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
