When I do the clutch fluid bleeding to my Nissan Maxima 96, I can push the fluid out of the slave valve. However, I don't see any fluid move from the reservoir into the master cylinder when I press and lift the clutch pedal many time.
How come the master cylinder will not suck fluid from the reservoir? By the way, the reason I bled my clutch hydraulic system is because the clutch becomes soft when I start the car with cold. After 5-10 minutes the car running, the clutch pedal becomes normal.
