I've had the S70 for a while now and have not become 100% accustomed to the clutch action. I reached the conclusion that the hydraulic release is a little slow to react, so I bled it to remove any air that may have been in the system. It made no difference, but the pedal does seem a little slow to rise if I snap my foot away when it's fully depressed. My previous cars have had cable operated clutches and have returned instantly. On the Volvo, the full return stroke of the pedal takes around half a second and is accomponied by a whooshing noise. Is this a damping effect, characteristic of hydraulic releases, or do I have a hydraulic problem?
BTW, there is no sound when pushing the clutch out or when letting it in steadily, only when I release it suddenly.
