Two technicians are discussing bleeding a hydraulic clutch. Technician A says to open the bleeder and allow the fluid to gravity bleed. Technician B says to have an assistant slowly depress the clutch pedal as the bleeder valve is opened at the slave cylinder to bleed the air out of the system. Which technician is correct?

Both methods described by Technician A and Technician B are valid techniques for bleeding a hydraulic clutch system. Gravity bleeding involves opening the bleeder valve and allowing fluid to flow out by gravity until air bubbles are no longer seen, while the method described by Technician B involves manually pumping the clutch pedal to force air out of the system, which is also a common and effective approach.
