He goes further with an explanation of the bleed alternative:

Alternative: Have the clutch hydraulics bled. This takes a competent technician about an hour and requires a lift. Cost is around $125. But the procedure includes some inherent difficulties:
• A hard, constricted reach with a tool to loosen the bleeder valve in its barely accessible position.
• A messy job because fluid dribbles into the bell-housing and all over adjacent surfaces.
• Need for two people, one at the bleeder valve, the other at the clutch pedal; or, if using a pump tool, the other keeping the clutch reservoir filled.
• if not done right, residual air will remain in the hydraulics, causing continued pedal issues.
• if crud has built up in the actuator (slave), a simple bleed won't dislodge it.
• Under the best of circumstances, the clutch will need bleeding each time the clutch fluid deteriorates. Not a cheap approach.

Our bleed is easier...as the bleeder valve is not as difficult to reach, not messy. However, the need for two people and the possibility of residual air remaining in the hydraulics if done incorrectly can cause problems...
