Recently did mine. The slave cyl was leaking. Replaced
both the clutch master cylinder and the slave cylinder.
Note: You will need 7mm for bleed screw, 12mm crowsfoot
flare nut wrench,12 mm flare nut wrench, 13mm flex socket and or 13mm s-shaped obstruction wrench and long extension(s), if doing both cylinders.
With one cylinder out, I figured the other one might not
be far behind. So I replaced both.
Hope this helps,
