2. Preparation

Tools：ratchet, ratchet rod, 8#, 13#, 15#, 19#, 20#, 32# sleeve,
11#, 13#, 14#, 17#, 30# box end wrench, vices, torque
spanner.
Accessories: brake fluid

3. Note

3.1 Wear necessary labor protection supplies to avoid
accidents.
3.2 Brake fluid is a kind of toxic liquid; if contact with skin or
eyes, please wash using large quantity of fresh water, and go
to a doctor if necessary.
3.3 Waste brake fluid shall be put into vessels. It is prohibited
to pour into sewerage or stack with domestic wastes.
3.4 When carrying out disassembly and assembly, never step
on the brake pedal nor move the vehicle.
3.5 Keep oil or liquid away from friction lining or friction
disk, it may affect brake performance.

4. Disassembly procedure

4.1 Unscrew tire clamp nut clockwise using 19#

torque spanner or driver's spanner and then remove the

tire.

Torque: 110N.m

4.2 Loosen the connecting bolt of brake caliper

assembly and steering knuckle using torque

spanner and 17# sleeve.

Torque: 85±5N.m

4.3 Use 11# and 19# box end wrench to unscrew

the connecting nut of brake hose and copper tube.

( if only replace friction disk, it is unnecessary to

loosen the brake line)

Caution: brake fluid is toxic,

when disassembling brake hose, always avoid brake

fluid to splash onto clothing or skin.

then separate brake caliper and brake hose.

4.5 Use punch to drift the lock trough, which drives

nut shim from semi-axle head, until it is able to turn.

4.6Remove the driving nut using 32# sleeve and

torque spanner. Torque: 180±10 N.m

4.7 Use cross screwdriver to unscrew the fastening

screw of brake disk, and then remove the brake disk.

Torque: 7-9 N.m

4.8 Check the thickness of brake disk, if it is less than

minimum thickness, replace accordingly. Caution:

replace the two brake disks of the same vehicle axles

together, and when using new brake disks, the replace

friction lining at the same time.

4.9 Check the max. circular runout of brake disk

end face via dial indicator, if it is greater than

0.03mm, replace accordingly. (If the brake disk

thickness can be guaranteed, appropriate mechanical

processing also can be performed to satisfy maximum.

circular runout)

4.10 Remove the connecting nut of knuckle and

control arm using torque spanner and 18# sleeve.

Torque: 110±5N.m

4.11 Remove three fixing bolts of hub bearing unit and

knuckle using 17# sleeve.

Torque: 120-128 N.m

4.12 Dismount the monitoring harness of friction lining

thickness from bracket.

4.13 Dismount brake caliper assembly.

4.14 Removal of brake caliper assembly:

4.14.1 Remove the fixing bolt of brake caliper bracket

respectively using a 13# and a 15# open-end wrench.

Torque: 22-23N.m
