I took my focus into the shop cause the clutch wasn't working. The mechanic told me it was the slave cylinder. I did all kinds of searches on this, but nothing helps. I've only had this car 7 months and probably should have done a little more research on it before i bought it, but it was a hatchback, it said SVT, it was in my price range, and some other person was trying to buy it who knew less about it than i did. I definitely want to learn more about it so if someone could please explain to me what the eff a slave cylinder does that would be great.

For the record, i feel like a complete tard asking this. : )
