Steve,
Pressing the clutch pedal moves the diaphragm spring that holds the pressure plate against the flywheel. The formula is that the force applied to the spring multiplied times the distance it must travel to release the pressure plate is equal to the force applied to the clutch pedal multiplied by the distance the pedal travels. That means you can reduce the pedal pressure by either going to a weaker diaphragm spring (i.e., a new clutch), or by adjusting the pedal mechanism to give you a softer but longer pedal movement. ... If the mechaism between the pedal and the pressure plate (e.g., a cable system or hydraulic master/slave cylinder) is not working correctly or is sized wrong, it can also contribute to a heavy clutch pedal. That is why the previous poster asked for more details.
