mm (0.16 in)], remove pin from reservoir tank.

3.

Remove master cylinder assembly from vise.

4.

Remove reservoir tank and grommet from cylinder body.

5.

While pushing primary piston, remove piston stopper through
secondary tank boss hole in the cylinder body.

6.

Remove snap ring with pushing primary piston.

CAUTION:

Be careful not to pop out piston. 

7.

Holding rod of primary piston, remove primary piston assembly,
plate and guide assembly by pulling straight to prevent piston
cup from being caught by the inner wall of cylinder.

8.

Remove plate and guide assembly from primary piston.

CAUTION:

Be careful not to damage rod from the inner wall of plate.

9.

Tap flange using a soft block such as wood, and carefully pull
secondary piston assembly straight out to prevent cylinder inner
wall from being damaged.

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.
• Make sure that there is no foreign material such as dirt and dust on the inner wall of cylinder, piston,

and piston cup. Be careful not to damage parts with a service tool when assembling.

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. 

6.

Apply brake fluid to a grommet, and press it into reservoir tank to install.
