I changed clutch on my 1.2 16v as the clutch fingers were bent. The clutch pedal was always really heavy. So i installed new ckutch 3 piece and now the clutch pedal is so light. But after a couple of weeks i swear its getting hard to push pedal down. What could caulse a clutch pedal to go from really light to heavy? Its a new clutch..Clutch cable is fairly new too.maybe auto tensioner on the clutch pedal? Hope anyone can help im worried something is wrong and damaging new clutch
