I have 2005 C6 and clutch petal goes to the floor. It sounds like i need to replace the clutch master cylinder. Does anyone know how to do that. Can't get it fixed under warranty becasue the car is salvage. thanks

Ifs its a Salvage title, you will have to pay to get it replaced. Is there fluid in the system. Is there a leak under the bell housing? You have to remove a lot of parts to get to the slave cylinder. Its a simple hydraulic system, if theres no pressure and the resevior is full, no leaks, then get it replaced.
