Ok. This just happened last night. I just installed a fresh pair of KSport coilovers on my 08 G. The second we pull out of my garage the pedal goes to the floor. Then came back. But the Resovuir is half full. 30 mins later the Resovuir is dry. And it's Leaking from where the Trans and engine meets... So. I've had the heavy duty csc for about 9 months. I recently had to put my old stage 2 xtd clutch in because my jwt kit broke. Something went wrong and the disc like ripped apart. ( yes I can drive..) the only thing I found was that the bearing on the csc was bent alittle. But it drove fine for about 1500 till last night. Pedal was a little vibraty. But it was OK. Anyone have experience with this? Why this heavy duty csc broke. I spend the 300 dollars so I never have to replace it... Could. It be the stage 2 kit pressure plate being too much clamping force for it??? Any opinions.


Last night before it broke..

 

It most likely got damaged when the JWT clutch blew apart on you, If the disk breaks it will cause improper movement of the slave as the pressure plate will not be even any longer making the bearing go crooked and damaging the unit.

Much like any other release bearing it should be replaced/rebuilt when the was clutch changed esp if the old clutch broke.

As you stated the pedal was "vibraty" This would indicate a clutch issue with the new XTD clutch as the only way it could vibrate would be if the fingers on the pressure plate are uneven. This is normally the case with cheap, poor quality clutches
