Toyota Repair: clutch repair, clutch slave cylinder, foot clutch

Question
Clutch pedal has hit the floor. need to pull pedal up using hand or foot. Clutch point close to floor. happened suddenly. Clutch master and slave cylinders are ok. Think it is release fork (presses against slave piston) that has failed due to fatigue. Can it be changed easily and how do you change it?

Answer
Check the operation of the clutch slave cylinder, does it move the clutch release arm when someone pushes the pedal down? If not there is a hydraulic leak somewhere either the master or slave cylinder or one of them has internal failure that is not visible from the outside, if the clutch arm moves at least one and a half inches then the problem is inside the bellhousing, probably the clutch.
