| They are notorious for not bleeding very easily. You may have to try again???
Are you pumping fluid out, when bleeding, thru' pulling the clutch lever?? Damaged clutch master cylinder?
When you had the slave cylinder off, did you remove the pushrod? Is it moving OK?
Does the slave cylinder move at all whilst removed? If it does, then I'd reckon you've just got to bleed it until it works.......... |
