What is more common for failure, slave or master cylinder? I am having trouble with clutch pedal travel. The clutch engagement is closer to the floor and i'm not getting full pedal pressure like I used to. I start to feel pressure like halfway down. I'd hate to be out and my clutch not return, that would suck! I suspect I need to re-bleed the clutch or the slave or master cylinder is going bad. Symptoms sound familiar to anyone?
