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.

6. Remove the return spring and ratchet adjuster assem-
bly.

Caution: If it is the riveted structure, there is no need to
remove the parking brake lever, instead of replace the
brake trailing shoe assembly.
8. Remove the brake wheel cylinder.
(a) Remove the brake line with a M10 open-end wrench,
and use a clean plug to clog it.
(b) Use a M8 open-end wrench to remove the two bolts, thus
removing the wheel cylinder assembly.
9. Remove the following parts from the wheel cylinder as-
sembly.
(a) Two dust covers.
(b) Two pistons.
(c) One piston spring.
(d) Bleed screw.

Brake components inspection
and maintenance
1. Inspect the components after disassembly.
After disassembling the components, check them for wear
and tear, rust, and damage.
2. Measure the rear brake drum's internal diameter.
Standard internal diameter: Ф200 mm
Maximum internal diameter: Ф201 mm

(a) Apply a small amount of lithium grease onto two piston
assemblies.
(b) Install the wheel cylinder assembly.
• Install two dust covers onto the two piston assemblies.
• Install a piston spring and two piston components in the

directions.
2. Install the wheel cylinder assembly.
(a) Use two bolts to install the wheel cylinder assembly
onto the brake back plate assembly.
Tightening torque: 7.8-11.8 N·m
(b) Connect the brake line to the wheel cylinder assembly.
Tightening torque: 16 N·m
3. Apply an appropriate amount of grease to the following
parts.
(a) Apply a small amount of high temperature resistant
grease on the brake back plate assembly and the brake
shoe connection's six convex plate surface.
Caution: Refer to the diagram for installation directions.

7. Install the brake cable connector on the brake trailing
shoe with brake lever assembly.
(a) Install the brake cable connector on the brake trailing
shoe with brake lever assembly.
(b) Insert the brake trailing shoe with brake lever assembly
and the shoe end of the brake leading shoe assembly
into the wheel cylinder assembly.
Remark: Do not let oil or grease drip on the brake shoe's
lining.
8. Install the retainer spring.
9. Install the brake leading and trailing shoe assemblies
onto the brake back plate assembly.
(a) Insert the pressure spring bar into the brake back plate
assembly and brake leading and trailing shoe assemblies.
(b) Put the pressure spring on the pressure spring bar,
put in the pressure spring cap, and use SST (Special
Service Tools) to lock the pressure spring cap onto the
pressure spring bar.
10. Inspect the operating procedures of the automatic ad-
juster.
(a) Refer to the diagram for directions, step on and off the
brake pedal, and make sure the self-adjusting screws
can rotate. If they are unable to rotate, inspect the rear
brake to try to determine the source of the problem.
(b) Adjust the adjusting mechanisms length and make it as
short as possible.
(c) Install the rear brake drum.
(d) Press the brake pedal towards the floor until a clicking
noise cannot be heard.
11. Inspect the space between the brake's friction plate
and rear brake drum.
(a) Remove the rear brake drum.
(b) Measure the rear brake drum's internal diameter and
the brake shoe friction plate's external diameter, and
inspect if the difference between the two diameters is
within the regulated clearance range.
Single sided clearance: 0.25 mm
If not correct, inspect the braking system.
12. Install the rear wheel.
Tightening torque: 100 N·m
13. Fill the brake fluid reservoir up with brake fluid and
exhaust the air out of the brake system.
14. Check for leaking brake fluid

4. Measure the rear brake drum's outer end surface
runout.
S t i c k a d i a l i n d i c a t o r m a g n e t t o t h e r e a r w h e e l h u b ' s
mounting bracket. Point the dial indicator to the rear brake
drum's outer end surface diameter at about a Φ136 mm
circumference (refer to diagrams dotted line area). Rotate the
rear brake drum, measure its runout, and maximum runout
0.11 mm is approval.
Caution: When the runout exceeds the maximum limit
of 0.11 mm, the rear hub unit should be replaced.
5. Remove the rear brake drum (See rear brake removal
step 4).
6. Examine the rear hub unit's starting torque.
(a) M a n u a l l y r o t a t e t h e r e a r h u b u n i t a n d c h e c k f o r
abnormal sounds or looseness. If the above problems
exist, it should be replaced with a new rear hub unit.
(b) Use a spring dynamometer to inspect the load applica-
tion.
Load application (when start the engine): 1 N·m
Caution: If the load application is greater than 1 N·m,
the rear wheel hub unit must be replaced.
7. Use calipers to measure the rear brake drum's internal
diameter.
If the measured result exceeds 201 mm, the drum brake must
be replaced.
Trailing arm spindle sleeve assembly removal
1. Examine the trailing arm spindle sleeve.
(a) Inspect the trailing arm spindle sleeve for deformities,
shifting, partial or serious cracks, and the gaskets for
loosening.
(b) If it's not easy to see clearly any existing damage of
the trailing arm spindle sleeve, take the following
steps: Use clean water to wash the trailing arm spindle
sleeve's rubber areas. At the same time rub it clean with
cotton. Check and make sure the rubber surface has
none of the previously mentioned flaws. If the above
flaws exist, replace with a the new trailing arm spindle
sleeve assembly.Cotton
