WHY would a new slave cylinder not make the clutch function, and why would I need to replace the brake master cylinder to make the clutch slave cylinder work. by the way I never have had a problem with the brakes,and still don't, but no clutch. Could a bad master cylinder make my clutch slave cylinder just go out

you would change the clutch MASTER cylinder then and being 11 years old from the previous conversation, I would change master and slave together anyway
