LuK Clutch Slave Cylinder Hydraulic Release Component

The LuK clutch slave cylinder (also called a hydraulic clutch release cylinder or clutch actuator cylinder) is a hydraulic component that helps disengage the clutch in a manual transmission vehicle. It turns hydraulic pressure from the clutch master cylinder into the mechanical movement that operates the release mechanism. This gives smooth, consistent pedal feel and clean gear changes.

Key Features:

• Hydraulic release design that transmits pedal input to the clutch release mechanism
• Made by LuK, a brand of Schaeffler and a long-standing original equipment supplier of clutch systems
• Built to meet OE specifications for fit, function and durability
• Sealed construction to help prevent fluid leaks and keep hydraulic pressure steady
• Replaces worn or leaking slave cylinders that cause a soft or sinking pedal, trouble shifting or incomplete clutch release

Replacing the slave cylinder during a clutch job is a common practice. It helps restore reliable clutch operation and can avoid repeat labor later. After installation, bleed the hydraulic system according to the vehicle manufacturer's procedure. Choose the correct child item for your application from the options on this page.
