2. Compressed air
DISASSEMBLY
1) Remove reservoir pin and reservoir.
2) Remove circlip.
3) For vehicle with ABS
Pull out primary piston assembly straight so as not to cause any
damage to inside of cylinder wall.
Pull out secondary piston assembly straight so as not to cause
any damage to inside of cylinder wall and by tapping flange with
a piece of wood or something soft.
3') For vehicle without ABS
Remove piston stopper bolt. Then remove secondary piston by
blowing compressed air into hole from which piston stopper bolt
was removed.
Be cautious during removal as secondary piston jumps out.
