I have a problem with my Z. When I start my car in the morning, the clutch pedal feels soft and mushy. When the car is cold, the clutch engagement point is almost near the floor. As I progressively drive the car, the clutch pedal starts to become firm and the engagement point is not close to the floor. I've bled both bleeding points just a week ago and the problem came back. I have fairly new clutch master and slave cylinders too. Should I bleed both bleeding points again or just the air nipple on the right side of the engine bay? I was reading a post and someone had the same symptoms as me. To cure his problem, he just bled the air nipple on the right side of the engine bay and not the slave. Should I also buy the ss clutch line while I'm at it?
