CHAPTER I BRAKE SYSTEM

SECTION I BRAKE SYSTEM PARAMETER

1) Check brake disc:

The friction surface of brake disc should be flat and has no apparent grooves; otherwise,
brake disc should be replaced.

2) Check the thickness of brake disc:

Use caliber rule to check the thickness of brake disc.

The standard thickness of front disc (ventilation disc) is 22mm with its operating limit of
19mm; when exceeding the operating limit, the front disc should be replaced.

The standard thickness of the rear disc (solid disc) is 10mm with its operating limit of 7mm;
when exceeding the operating limit, the rear disc should be replaced.

3) Check brake disc runout:

Use micrometer guage to check the runout degree of brake disc surface. The operating limits
of front disc and rear disc are both 0.03mm respectively.

4) Check the thickness of brake lining:

The standard thickness of front brake lining is19.3mm and the operating limit is 9mm. The
residual thickness of brake pad thickness limit should be not less than 1mm (coated plate:
5mm, noise insulator: 0.6m).

The standard thickness of rear-brake lining is 16mm with its operating limit of 8 mm. The
residual thickness of brake pad thickness limit should be not less than 1mm (coated plate:
5.5mm, noise insulator: 0.3m).

5) Remark:

Before dismounting the wheel, you should check the thickness of external brake lining
through the aperture in the wheel spoke, or dismount the wheel to have a check.

Important Notice:

² After replacing the friction lining or brake disc, you should step on the brake for several

times in order to ensure a break-in between the brake lining and brake disc. Thus, the
safety can be guaranteed.

²

After replacing the brake lining, you should check whether the brake fluid level is
positioning between MIN and MAX.

SECTION II DISASSEMBLY AND
ASSEMBLY OF REAR BRAKE

Needed tools: ratchet, ratchet rod, 8#, 13#,
15# and 20# sleeves, 13#, 14#, 17#, 30#
box end wrenches, vice clamp, torque
spanner and flat-tip screwdriver.

2.1

Disassembly sequence:

1)

Screw off the tire clamp nut and
dismount the tire.

Note: When dismounting the tire, you
should firstly loosen the 4 clamp nuts for
1-2 folds, and then screw off the nuts. Do
not scuff the bolt.

Torque: 110±10 N.m

2)

Use 13# box end wrench to screw off
the nut connecting the brake oil pipe
and the brake caliper, and discharge
the brake fluid.

Note: Since the brake fluid is poisonous,
you must keep your skin away from it.

Torque: 11-14 N.m

3)

Use 13# box end wrench to loosen the
bolts (2 pieces) connecting the brake
caliper and brake backing plate. And
then dismount the rear brake caliper
assembly.

Torque: 63±3N.m

4)

Use 30# box end wrench to screw off
the clamp nut of the wheel hub bearing
unit.

Torque: 78±5N.m

5)

Use 8# socket wrench to screw a M8
bolt into the bolthole illustrated in the
figure, and pack out the brake disc.

Note: When replacing brake disc, please
replace it in pair. No matter whatever
happens, you are not allowed to use hammer
or similar tools to hit the brake disc. If
necessary, you can use rubber hammer to
knock on the brake disc body.

6)

Take out the rear brake disc. Check the
thickness of brake disc, and replace the
brake disc when its thickness is less
than the specified minimum thickness.

7)

Use bearing puller to pull out the wheel
hub bearing unit.
