Front brake caliper assembly installation

1.  Preparations

Make sure all parts are clean and free of foreign materials 

before installation.When installing, apply an appropriate 

amount of rubber grease to the guide pin and piston's 

working surface, as well as the rectangular sealing ring and 

the piston protective cover's working surface.

2.  Install the rectangular sealing ring to the caliper.

(a)  Screw the bleed screw into the caliper's vent holes.

Tightening torque: 10±2 N·m 

(b)  After applying an appropriate amount of rubber grease 

on the rectangular sealing ring's working surface, install 

them into the caliper's seal groove.

3.  Install the piston with piston dust cover on the caliper.

(a)  Place the piston dust cover on the piston.

(b)  Stretch the piston dust cover, until its card holder 

exposes  the  bottom  of  the  piston.  Use  tools  (for 

example, about Ф2 mm of iron wire) to assist by 

stuffing the card holder into the cylinder bore card 

holder's groove.

Caution: The tools being used should not be sharp, as 

to avoid tearing the dust cover.  

(c)  Then manually press the piston into the bottom of the 

cylinder bore.

4.  Install the guide pin and guide pin dust cover onto the 

caliper frame.

(a)  Install the guide pin dust cover onto the guide pin.

(b)  Screw the guide pin into the caliper frame.

Caution: Do not damage the guide pin dust cover.

5.  Install an inner and outer brake pad assembly and 

inner and outer muffler plate subassembly.

6.  Install the brake block yoke spring plate as well as the 

inner and outer brake pad assembly and inner and 

outer muffler plate subassembly on the caliper frame.

7.  Install the caliper assembly.

(a)  Install the caliper assembly.

(b)  Install and tighten the hexagon bolt for flange face.

Tightening torque: 30±5 N·m 

8.  Connect the brake line.

Connect the brake pipeline to the caliper.

Tightening torque: 40±4 N·m

9.  Fill the brake reservoir up with brake fluid and exhaust 

the air from the brake system.

10. Check for leaking brake fluid.

Caution: Bleed the air after replacing.

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.

Brake System

Method two:

(a)  Find two M6×40 (the thread is longer than 25 mm) 

phillip screws, and screw them into the rear brake 

drum's two threaded holes.

(b)  Use a screwdriver to tighten the phillip screw, and push 

out the rear brake drum.

Caution: Alternately tighten the two screws.

5.  Remove the brake leading and trailing shoe assembly 

and adjusting paddle.

(a)  Use SST (Special Service Tools) to separate and remove 

the pressure spring cap of the brake leading and trail-

ing shoe assembly, and remove the pressure spring and 

pressure spring bar.

(b)  Take out the brake leading and trailing shoe assembly 

from the brake back plate assembly, take down the 

retainer spring, and remove the cable connector.

Remark: When taking out the brake leading and trailing 

shoe assembly from the brake back plate assembly, screw 

the adjusting clearance wheel thread completely into the 

adjusting clearance screw rod, decrease the return spring's 

tension on the brake leading and trailing shoe assembly.

(c)  Use needle nose pliers to remove the brake shoe tension 

spring, and take down the adjusting paddle.

(d)  Use pliers to remove the return spring from the brake 

leading and trailing shoe assembly, and separate the 

brake leading and trailing shoe assembly.
