How does a hydraulic clutch work on a Vanagon?
This master cylinder pushes hydraulic fluid through a 10-foot-long pipe running to the engine compartment, where it is connected to a similar piston-and-cylinder assembly known as the “slave cylinder”. This slave cylinder in turn actuates a lever on the side of the clutch bellhousing to engage & disengage the clutch.
Can a blocked slave cylinder bleed a clutch?
Please try again later. Blocking a clutch slave cylinder allows the clutch master cylinder to actually start flushing from the master cylinder down to bleed a clutch hydraulic system. This can only work with external slave cylinders that can safely and effectively be blocked.
What causes the clutch master cylinder to disengage?
It’s an important part of the transmission system, which works together with the clutch master cylinder and other components to disengage the clutch when the driver changes gear. The process begins when the driver depresses the clutch pedal. This causes the master cylinder to transfer the pressure onwards to the slave cylinder.

How is the clutch master cylinder connected to the transmission?
There is a pushrod on one end of the cylinder, and when you depress the clutch, you push this rod against the clutch fluid, which pushes it to the slave cylinder and eventually to the clutch fork in the transmission. The clutch master cylinder is what transfers the force of you pushing down the clutch pedal to the transmission!

How do you Bleed the clutch in a VW?
Start by carefully topping-up the fluid reservoir in the dash with fresh fluid. Unlike the brake hydraulic system, the clutch evidently cannot be bled simply by pumping the pedal; the air bubbles will only compress and expand instead of being forced out, so Volkswagen specifies that a vacuum-pump-actuated bleeder be used.
What causes a clutch slave cylinder to leak?
Because the clutch slave cylinder depends on hydraulics to function correctly, leaks are the most common issue to afflict them. Over time, regular use can wear down the component, allowing the transmission fluid inside to leak out.
Where is the clutch master and slave cylinder?
The cylinder is connected to the clutch master cylinder located on the firewall next to the brake master cylinder through a hose. When you push the clutch pedal, brake fluid flows from the clutch master cylinder to the slave cylinder, applying the pressure necessary to engage the clutch.
