Clutch issues and mechanics

The clutch pedal in a car is plays a crucial part in transmitting power from the engine to the transmission. Pressing the clutch pedal disengages the clutch plates from the flywheel, so that the gears can be changed without causing damage. Clutches, throw-out bearings, and clutch plates are designed to be engaged and disengaged over their lifetimes (usually about 60 - 90K miles, depending on how you drive). Don't ride the clutch when taking off from a stop! Make sure it is completely engaged (foot OFF the pedal) before accelerating from a dead stop.

Resting your foot on the clutch (and thus disengaging it) while accelerating will prematurely wear your clutch out. The reason why is because the flywheel is slipping on the surface of the clutch disc. This action wears friction material off of the face of the disc and thus renders the clutch useless in short order. In many cars the mechanics of clutches leave a lot of "play", so that the foot can be rested on the clutch pedal, and are only disengaged when pressed firmly.
