INSPECTION AFTER DISASSEMBLY
Cylinder Body
• Check the inner wall of cylinder for damage, wear, corrosion, and pin holes. Replace cylinder body if neces-
sary.
ASSEMBLY
CAUTION:
• Never use mineral oils such as kerosene or gasoline during the cleaning and assembly processes.

BRAKE MASTER CYLINDER
1.
Apply brake fluid to the inner wall of cylinder body, primary pis-
ton assembly and secondary piston assembly.
2.
Insert secondary piston and primary piston assembly into cylin-
der body in this order.
CAUTION:
• Pay attention to the orientation of piston cup, and insert
straight to prevent cup from being caught by the inner
wall of cylinder.
• Always replace inner kit as a set.
3.
Set the slit of secondary piston towards the piston stopper
mounting hole of cylinder body while pushing in the primary pis-
ton. Then install the piston stopper through the slit of secondary
piston.
4.
Insert plate and guide assembly into cylinder body.
CAUTION:
• Be careful not to damage rod of primary piston.
• Pay attention to the orientation of guide assembly.
• Do not drop O-ring.
• Be careful the guide and/or plate are not inserted at an
angle to cylinder inner wall.
5.
Be careful not to damage rod of primary piston with the cloth.
Then insert snap ring to cylinder body while pushing primary pis-
ton.
CAUTION:
Make sure that snap ring is securely engaged in cylinder
body inner diameter groove.
