Change of Brake pad
Remark: In case there is a continuous screaming from the front
wheel when braking the vehicle during driving, check the
alarm pad for friction limit for brake pad. If there is friction
trace on the alarm pad with the brake disc, change the brake pad
1. Disassemble the front wheel;
2. Check the thickness of friction material of brake pad.
Check the thickness of friction material of brake pad, if it fails
to be within the specified range, change the brake pad.

2. Measure the thickness of brake disc;
Standard thickness20.0mm
Min thickness18.0mm
If the brake pad is scraped, repair it; where the abrasion is
serious and its thickness is smaller than the min thickness,
change the brake disc.
3. Measure the bounding value of the brake disc face;
Remark: the bearing is required to be verified in the suitable
adjustment before measuring.
Max face bouncing value: 0.11mm;
4. Change the brake disc according to the requirement:
(a) Tear down the hub and the brake disc. (see the paragraph
of front wheel hub)
(b) Mount the new brake disc and screw up the connecting
bolts as the specified torque.
(c) Mount the hub and brake disc assembly. (see the para-
graph of front wheel hub).
Fastening torque(755)Nm
(d) Mount the caliper bracket on the steering knuckle and
screw up the bolts according to the specified torque.
Fastening torque123Nm.
Assembly of Brake-wheel pump
1. Preparation
All parts shall be washed, dried and cleared away the alien
materials, and coat moderate rubber lubricant on the work
faces of piston, piston dust cover and rectangular sealing ring.
2. Encase the piston sealing ring in the caliper body Braking SystemFront Brake(SF)

3. Encase the piston in the caliper body.
4. Encase the piston dust cover, dust cover steel-
gripping hoop in the caliper body.
Mount of Brake Calipers
1. Mount the brake caliper and screw up the two
mounting bolts.
Fastening torque123Nm
2. Mount the brake pads;
3. Connecting the brake pipeline;
Use the open spanner to connect the pipeline.
Fastening torque(211)Nm
4. Observe the height of brake liquid level and, if
necessary, add in the brake liquid and exhaust the air
in braking system.
Notice: avoid the brake liquid of spraying on the brake disc
when exhausting the air.
5. Check to see whether there is leakage of brake liquid. Braking SystemFront Brake(SF)

Disassembly of Rear drum-type Brake
Remark: if the braking torque of manual brake cannot satisfies
the braking requirement, it is suggested to check the thickness
of brake shoe liner, where the thickness is less than the min
thickness, change the brake shoe.
Min thickness1.0mm
1. Tear down the rear wheel;
2. Tear down the brake drum;
Remark: in case the brake drum is not easy to tear down, the
following steps shall be adapted:
(a) Tear down the clearance-adjusting hole; insert a screw-
driver in the brake bottom plate hole to prize up the
adjusting bolt inner tilt angle with the self-adjusting fork.
(b) Use another screwdriver to adjust the adjusting bolt inner
tilt angle to loosen the clearance adjuster of brake shoe. DrBraking SystemRear Brake (Dr)

right wheel forward
1. Assemble the wheel-brake cylinder:
(a) Coat moderate lithium soap base glycol grease on the
piston cup;
(b) Assemble the wheel-brake cylinder:
Mount the two piston cups on two piston;
Encase the spring and two pistons in the wheel cylinder
body and
Mount the two dust covers
Remark: Assembly shall be conducted correctly according to
the direction shown in the drawing.
2. Mount the wheel-brake cylinder:
(a) Use two bolts to fix the wheel-brake cylinder on the rear
bottom plate.
Coat moderate sealing glue (Glue 704) on the position where
the wheel-brake cylinder connects with the bottom plate.
Fastening torque(1620)Nm
(c) Connect the brake pipeline on the wheel-brake cylinder.
Fastening torque18Nm
3. Coat the following parts with moderate lubricant that
resistant high temperature (do not pollute the friction
plates);
(a) The upper plain of the hex convex platform where the
bottom plate connects the brake shoe;
(b) Contact face of the brake shoe and the top lever of wheel
cylinder;
(c) Contact face of the brake shoe with the support pin. Braking SystemRear Brake (DR)

12. Check the clearance between the brake shoe and the
brake drum:
(a) Tear down the brake drum;
(b) Measure the inner diameter of the brake drum and the
outer diameter of brake shoe to check whether the differ-
ence of the two diameters falls within the standard
clearance range.
Shoe clearance: 0.6mm
If it is not correct, check the parking brake system.
13. Mount the brake drum and the rear wheel; screw up
the nuts of rear wheel hub.
Fastening torque(14510)Nm
14. Fill the liquid container with brake liquid and exhaust
the air in braking system.
15. Check to see whether there is leakage of brake liquid.
