Important: Never use fluid that you have bled from a system to fill the reservoir. The fluid may be aerated or contaminated.

4. Open the bleed screw on the concentric slave cylinder in order to expel the air.
5. Close the bleed screw then release the clutch pedal.

Important: Ensure no air is drawn into the clutch system.

6. Repeat steps 2, 3, and 4 until all the air is out of the clutch system.
6.1. Check and refill the reservoir as needed while bleeding.
6.2. After bleeding, pump the clutch pedal several times. If the clutch engagement is not satisfactory, repeat the bleeding procedure.
7. If the previous procedures are unsuccessful, perform the following steps.
7.1. Remove the reservoir cap.
