I have a 2006 Corvette ZO6 with 27,000 miles on it.  Just completed a clutch and new torque tube including driveline replacement. I put an aftermarket Tilton clutch in with a Tilton series 6000 clutch slave bearing in as well.  Did all the measurements necessary per Tilton. While doing the initial first running of the car at idle in neutral, all was good. Clutch pedal felt good etc. ( Clutch master was bled out correctly beforehand) Then all clutch feel disappeared. Pedal went to the floor. Clutch master reservoir empty, and fluid leaking out the bell housing. I suspect a faulty clutch slave but not sure.  I am very frustrated as this was an immense amount of work.  Any ideas here? I am waiting for Tilton tech to get back to me but fear they will blame me and not their part.  Again frustrating.
