I just had an ACT clutch and Gruppe-s flywheel installed. When the car is not moving and I barely press the pedal in no more than an inch I can feel vibration through the pedal. I did some searching and found quite a few people experiance this but could not determine if it is normal or a problem. The car drives and shifts fine. I only have 150 miles on the clutch so its still not broken in yet. So can someone please tell me if this is normal?

 

anybody????

 

I had this problem when i got my car back from the bodyshop when i got in my accident....It was my slave cylinder...What happened was coolant got inside and rusted the internals and was causing vibration in the pedal...So i changed it and everything was fine after that...Hope this helps....

 

This happened to my friends car before the Throw out bearing broke off from the pressure plate. however, this was after 40k of driving on the exedy stage 1 clutch kit.
but, i would check the slave cylinder bolts and see if they where tight.

 

same deal here with an exedy twin disk carbon....this is my second carbon and didnt have the vibration on the last car.
