Clutch System Introduction
Free pedal is the distance the clutch pedal moves by
applying only slight pressure. During free pedal the
release yoke in the transmission moves until its bearing
pads contact the release bearing. This movement of the
release yoke is called free travel. Thus, free pedal and
free travel are directly related to each other.
