No, when the clutch pedal is in, the friction material is totally disengaged from the flywheel. In neutral, it will be clamped to the flywheel and freewheeling on the input shaft of the transmission. Neither will wear the clutch any faster. What wears the clutch is:
1. Hard high RPM shifting
2. Dropping the clutch when the motor is revved much higher than the engaged gear would anticipate at that RPM. <-- That didn't make a whole lot of sense...
Go to howstuffworks.com and you will understand much better. I read up on brake boosters last night and those things are amazing!
