5. Dismantle the dust cover of the oil cylinder 
Use a screwdriver to dismantle the dust cover of  
the oil cylinder.  
 
 
 
 
 
 
 
 
 
6. Dismantle the piston 
(1) Prepare one wooden panel to hold the piston; place  
the wooden panel between the pistons and insert the  
washer on one side.  
(2) Carefully blow compressed air into the joint hole to  
push out the piston. Place one shield plate (hard wooden  
plate, etc) on the notch of brake caliper to protect the  
piston. Do not hold the piston in hand, or your fingers 
might be in danger of being clamped.

7. Check the guide sleeve (5) 
Manually handle the guide sleeve to check if it is flexible  
enough, in case of stuck problem, the guide sleeve shall be  
replaced.  
Caution: apply lubricating grease on the guide sleeve during 
fixing.  
 
 
 
8. Carefully dismantle the seal with a rubber needle 
Clean the brake cylinder and components with alcohol and  
then blow dry with compressed air. Carefully check the  
surfaces of brake cylinders, pistons and flanges. No machining  

027

of brake cylinder and piston is allowed.  
 
 
 
 
 
9. Fixing instructions 

028

Apply one thin film of brake cylinder ointment on the brake 
cylinder, piston and seal and then fix the O-ring into the  
annulus groove on the back of the brake cylinder. Fix and press 
the whole dust seal into the front annulus groove.  
 
 
 
 
 
 
 

029

Fixing instructions:  
Keep the clearance between dust seal and brake caliper body 
dry and free of brake cylinder ointment or brake fluid 
to ensure the precise position of the dust seal.  
 
 
 
10. Use an elongated piece to secure the brake piston,   
slightly press it against the dust seal and blow the dust  

030

seal with compressed air (max. pressure 3bar). Hitch 
the snap ring onto the bake piston.  
Fixing instructions:  
Soak the dust seal and brake piston with brake fluid so that  
the dust seal may pass easily.

Inspection and maintenance 
1. Measure the thickness of brake pads. 
Measure the thickness of brake pads with a ruler. 
Nominal thickness: (19) 
Minimum thickness: (6) 
Any brake pads whose thickness is the same as or less than the  
minimum thickness or which are severely worn out and 
uneven shall be replaced.  
2. Check brake lining abrasion sensor 
(1) Detach the linker of abrasion indicator of brake lining. 
(2) Check if the abrasion indicator of brake lining is on, if failed,  
the indicator shall be replaced.  
(3) Connect the linker to the speed sensor, until a “click” is heard.

3. Measure brake disc thickness 
 
Standard thickness: (22) 
Maximum thickness: (9.9) 
Any brake pads whose thickness is the same as or less than the  
minimum thickness shall be replaced. Any brake disc which 
has scratches or abrasion on the surface shall be ground on a 
machine tool or replaced.

4. Measure the lateral runout of brake disc 

035

(1) Secure the brake disc with 2 wheel hub nuts 
Tips: hold the brake disc with a special clamp  
during measurement. 
Torque: (110N.m)

(2) Measure the lateral runout of brake 
disc 10mm off the outer rim of the brake 
disc with a dial indicator. Maximum 
lateral runout of the brake disc: ( ); if the 
lateral runout value is bigger or the same 
as the maximum lateral runout value, then 
the axial clearance of the bearing and the 
lateral runout of the axle shall be checked. 
If the axial clearance and the lateral 
runout of the axle are normal, then brake 
disc may be modified for its lateral runout.
