Only time I lost it was with Autozone when that second clutch slave was defective and the manager did not give a darn.. That was a job from hell. Of course it was on the daughters car also.
I havent had to put in a labour claim yet, but on a faulty clutch slave,2x? Yup. I wouldnt back off until i got something.some of those hydraulic slaves are total crap. **** design if you ask me.
