So when my dad and I changed the clutch on my car he took the fluid line off the slave cylinder and the clutch pedal went to the floor. No problem we'll just bleed it and put new fluid in it. .. The fluid was rather dirty and when we went to put everything back together and clutch would not pump up, I would sort of feel some resistance building up but very very quickly stopped. Thinking that all the dirt in the master cylinder kept the seal and kept it working. Just want to know if it really is the master cylinder, because my car is sitting 30 miles away at my uncles, so i want to make sure that, that's the problem. Thanks for any help you can give me.
