Common Problems This Part Can Address

• Pedal travel changes caused by internal seal wear
• Loss of hydraulic pressure in the clutch release system

Installation Notes

• Verify vehicle year, make, model, and hydraulic clutch configuration before installation.
• Bleed the clutch hydraulic system after installation because the unit is not pre-bled.
• Fill the system with the correct fluid during service, as pre-filled fluid is not included.
• Inspect the push rod connection and related hydraulic components for wear before reassembly.
• Because the clutch slave cylinder is not included, confirm the existing slave cylinder condition during diagnosis.
