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

Rear hub unit inspection and removal

1. Manually rotate the wheel according to the diagram,

and check the bearing of the rear hub unit for abnormal

noises and stiff rotation. If these flaws exist, please

replace the rear hub unit.

2. Remove the wheel.

3. Manually screw the two wheel nut's opposite angles on the

wheel bolt and fixed rear brake drum.

Remark: Alternately tighten the two nuts, and manually

screw it down as much as possible.

4. Measure the rear brake drum's outer end surface

runout.

Stick a dial indicator magnet to the rear wheel hub'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) Manually rotate the rear hub unit and check for

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.

2. Remove the trailing arm spindle sleeve.

(a) Mark with a white paint pen, and remember the

direction of the trailing arm spindle sleeve assembly .

(b) The trailing arm spindle sleeve is a disposable part. If

it is damaged, first use a pry bar to lift up the edge of

the trailing arm spindle sleeve's outer tube in order to

install SST.

(c) Use SST (Special Service Tools) to clog the spindle

sleeve's installation tube. Tighten the two bolts, twist

them with a wrench and push out the spindle sleeve.

Caution: When performing the pressing out process,

be certain to ensure the trailing arm spindle sleeve is

vertically forced out.

3. Install the new trailing arm spindle sleeve with nylon

bushing assembly.

(a) Before installing the new trailing arm spindle sleeve

with nylon bushing assembly, first distinguish the

installation direction for the trailing arm spindle

sleeve's nylon bushing assembly, whereas the direction

of the nylon lining's four holes face one end of the

trailing arm.

Caution: Do not install the trailing arm spindle sleeve

with nylon bushing assembly in the opposite direction.

(b) Use SST to position the trailing arm spindle sleeve with

nylon bushing assembly, and slowly press it in.

Caution: When performing the pressing process, be

certain to ensure the trailing arm spindle sleeve is

vertically forced in.
