Installation Notes and Tips
Verify the hydraulic line connection, pedal linkage, and push rod fitment before installation. Because this unit is not pre-bled and does not include a slave cylinder, the hydraulic system must be filled and bled after installation. Follow the included instructions and inspect the rest of the clutch hydraulic system for wear before returning the vehicle to service.
