Common Applications and Issues Addressed

• Eliminates clutch engagement problems caused by master cylinder failure

Installation Notes and Tips

Installation instructions are included with the Luk LMC454 clutch master cylinder to assist with proper fitting. Since the unit is not pre-filled or pre-bled, it is essential to fill the hydraulic system with the recommended brake fluid and bleed the system thoroughly to remove air pockets. The push rod included should be adjusted to ensure correct pedal travel and engagement. Because this part does not include a clutch slave cylinder, verify the condition of the slave cylinder during installation and replace if necessary. Proper installation will help maintain consistent clutch performance and extend the life of the transmission components.
