6.  Remove the return spring and ratchet  adjuster assem-

bly.

(a)  Remove the adjusting clearance shaft head.

(b)  Remove the adjusting clearance wheel.

(c)  Remove the return spring.

7.  Remove the parking brake lever.

(a)  Remove the split ring with pliers.

(b)  Remove the brake lever rotating shaft.

(c)  Remove the brake lever.

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.

(e)  Bleed screw cap.

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

Brake System

3.  Measure friction plate thickness.

Standard thickness: 4.0 mm

Minimum thickness: 1.0 mm

If the friction plate thickness is smaller than the minimum 

value or produces uneven wear and tear, the brake leading 

and trailing shoe assemblies should be replaced.

Remark: If one of the brake shoe assembly needs to be 

replaced, be sure to replace all the rear brake leading and 

trailing shoe assemblies to ensure even braking ability.

4.  Check to make sure the contacts of the friction plate 

and rear brake drum are fine.

If the contacts of the friction plate and rear brake drum is not 

good, the brake leading and trailing shoe assemblies should 

be replaced.

Rear Brake Installation

1.  Install the brake wheel cylinder.

(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 

   wheel cylinder body.

Remark:  Refer  to  the  diagram  for  precise  installation 

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.

Brake System

(b)  Apply a small amount of lithium grease on the brake 

leading shoe assembly and brake trailing shoe assembly 

(refer to the arrows in the diagram for indicated areas).

Remark: Do not contaminate the friction plate.

(c)  Insert the return spring into the adjusting clearance 

screw rod and apply an appropriate amount of lithium  

grease on the adjusting clearance wheel's thread and 

screw, adjusting clearance screw rod's shaft head, 

and adjusting clearance shaft's shaft head (refer to the 

arrows in the diagram for locations).

4.  Install the brake lever on the brake trailing shoe as-

sembly.

(a)  Install the parking brake lever and insert the lever rotat-

ing shaft.

(b)  Use pliers to install a new split ring in the lever rotating 

shaft.

5.  Install the return spring and ratchet adjuster assembly 

on the brake leading shoe assembly and brake trailing 

shoe with brake lever assembly.

Hang one side of the return spring on the brake leading shoe 

assembly, and use pliers to hang the other side of the return 

spring on the brake trailing shoe with brake lever assembly.

6.  Install the adjusting paddle on the brake leading shoe 

assembly.

(a)  Install the adjusting paddle on the brake leading shoe 

assembly.

(b)  Use needle nose pliers to install the brake shoe tension 

spring on the adjusting paddle and brake leading shoe 

assembly.
