Steering Knuckle and Hub Brake Assembly
Components
Disposable parts
Steering knuckle and hub brake assembly
examination and disassembly
1. Hoist the vehicle and remove the wheels.
2. Loosen the riveted areas of the front drive shaft nut
and remove the nut.
3. Inspect the front brake disc plate surface runout.
When measuring, tighten the two wheel nuts' symmetrical
locations. The front brake disc's brake linings runout on the
two sides should be no more than 0.11 mm. If oversized,
they should be repaired or replaced.
4. Inspect front brake disc thickness.
Standard thickness: 22.0 mm
Minimum thickness: 20.0 mm
The brake disc must be changed when it reaches the minimum
level of thickness.

(d) Measure the front hub bearing's starting torque.
Put the SST on the wheel bolts which are at the symmetric
locations. Put a dial torque wrench on the SST to slowly
rotate the flange assembly (45°/4s), requiring a starting
torque range of 0.1-0.3 N·m.
If the bearing rotation is not flexible, the front hub flange
plate surface movement inaccurate, or front hub bearing
starting torque is too much. The assembly must be replaced.
Steering knuckle's front hub bearing and
front hub flange assembly
1. Removal and inspection of front hub flange assembly.
(a) Use SST like a hand held travel hammer to repeatedly
hammer off the front hub flange assembly from the
steering knuckle and front hub bearing. Remove the
front hub with bearing's inner ring.
(b) Remove the bearing's inner ring on the front hub.
Use SST to remove the bearing's inner ring.

(c) Use dye penetrant to inspect the front hub flange for
cracks, which should be replaced if found.
(d) If one would like to continue using the front hub flange
assembly, first inspect the dimensions for the mounting
area of the bearing for inaccurate dimensions. If
oversized, replace.
Measurement range: Φ38+0.025 +0.009 mm
2. Remove the steering knuckle's front hub bearing.
3. Remove the snap ring for hole 72.
Use a bent nose retaining ring caliper for holes to remove the
snap ring for hole 72.

3. Examine the front hub flange plate surface runout.
Examining methods are the same as the methods used
during disassembly. Plate surface runout should not exceed
0.03 mm.
4. Examine the front hub bearing assembly's starting
torque.
Examining methods are the same as the methods used during
disassembly. Put the SST on the wheel bolts which are at the
symmetrical locations. Put a dial torque wrench on the SST to
slowly rotate the flange's flange assembly (45°/4s), which re-
quires a starting torque range of 0.1-0.3 N·m
5. Install the snap ring for hole 72.
Use a bent nose retaining ring caliper for holes to install the
snap ring for hole 72 at the steering knuckle's retaining ring
mounting position.
6. Install the steering knuckle's front hub bearing and
front hub flange assembly.
7. Install the front brake disc cover.
Install the front brake disc cover on the steering knuckle, and
tighten the bolt to the set torque.
Tightening torque: 9±2 N·m

9. Examine the front brake disc plate surface runout.
When measuring, tighten the two wheel nut's symmetrical
locations. The front brake disc's brake linings runout on the
two sides should be less than 0.11 mm.
10. Install the brake caliper assembly.
Install the brake caliper on the steering knuckle, and tighten
the bolt according to the set torque.
Tightening torque: 100±10 N·m

Disposable parts
Inner and outer brake pad assembly re-
placement
Remark: When applying the brake while driving, if the front
tires makes a continuous screeching sound, inspect the inner
and outer brake pad and friction limit alarm plate. If there
are traces of rubbing from the brake disc on the alarm plate,
the inner and outer brake pad assembly should be replaced.
1. Remove the front wheel.
2. Inspect the inner and outer brake pad's friction material
thickness.
By looking through the caliper's observation ports, inspect
the inner and outer brake pad friction material thickness. If it
is no longer within the specified range, it should be replaced.

8. Install a new inner and outer brake pad assembly and
inner and outer muffler plate subassembly.
(a) Install inner shim A and B onto the inner brake disc.
(b) Install outer shim A and B onto the outer brake disc.
(c) Install the inner and outer brake pad assembly with
inner muffler plate subassembly onto the caliper frame.
Make the inner brake pad assembly with inner muffler
plate subassembly and alarm plate rest close to the
brake caliper's inner side.
Caution: For the inner and outer brake pad assembly,
the working surface of the brake disc must not have
any grease, oil or paint pollution.
(d) S i p h o n a s m a l l a m o u n t o f b r a k e f l u i d f r o m t h e

from the reservoir).
(e) Press in the piston with SST.
9. Install the caliper assembly.
Loosen the rope, remove the caliper assembly, and tighten
the hexagon bolt for flange face.
Tightening torque: 30±5 N·m
Remark: Replace one wheel's brake pad at a time, in order to
avoid the other wheel's piston from springing out.
10. Install the front wheel.
Tightening torque for the wheel retaining nut: 100±5 N·m

1. Remove the brake line.
Remove the brake line, and use a clean container to hold the
brake fluid.

Rear Brake
Components
4. Remove the rear brake drum.
Remark: If it is difficult to remove the rear brake drum,
follow the steps below:
Method one:
(a) Remove the rubber plug of the adjuster's observation
port, and insert a slotted screwdriver into the brake's
back plate assembly hole, and pry off the adjusting
paddle from the adjusting clearance wheel.
(b) Use another slotted screwdriver to toggle the adjusting
clearance wheel and loosen the brake's leading and
trailing shoe assembly's tension on the rear brake drum.

Rear brake removal
1. Inspecting the brake's friction plate thickness.
Remove the rubber plug of the observation port gap and
examine the friction plate thickness via the observation port.
If it's smaller than the minimum value, the brake's leading
and trailing shoe assemblies should be replaced.
Minimum thickness: 1.0 mm
2. Remove the rear wheel.
3. Release the brake fluid.
Caution: Be sure not to spill the brake fluid onto the
paint's surface. Otherwise it must be immediately
cleaned.
