yep bad slave cyclinder..if wet or really dirty black then replace.possible line may ave a pinhole or rub spot replace them bothSo, Im coming home from work and when I go to start from a stop sign, my clutch pedal dropped to the floor with almost no resistance except for the last couple inches. I was able to force it into gear but a short while later it wouldn't go into gear and I found myself in the side of the road. The clutch pedal sinks like a rock. I checked the reservoir and it was low so, I topped it off. Still no pressure. Maybe there's air in a line? Ill bleed it but, if that doesn't work does anyone know what I should check next?
