I'm resurrecting this thread to ask a question about troubleshooting the hydraulic clutch. It was the only thread I can find, searching the brake forum, on the hydraulic clutch. My problem isn't with my Z, but it might as well be, as the Subaru clutch seems identical.
The problem is the clutch will slowly lose travel. I can bleed the slave, and it will work again, for a while (a week or so). There seems to be no fluid loss, just air getting pumped in. Where is the fault more likely - the slave or the master? I'd rather not shotgun it if I can help it.
Thanks.
