Two people are required to bleed the clutch cylinder. Do not use vacuum assist or any type of power bleeder. It will not purge all the air from this system.
Fill master cylinder reservoir with new brake fluid.
Connect a clear tube to the bleeding connector on the Concentric Slave Cylinder (CSC).
Push and release the clutch pedal slowly and fully 15 times, waiting 3 seconds between each cycle.
Push in the lock pin on the bleeding connector and hold it in.
Hold the lock pin in to prevent the bleeding connector from separating when fluid pressure is applied.
Slide the bleeding connector out
(5mm), then press the clutch pedal and hold it down.
Push the bleeding connector back in and release the clutch pedal.
Repeat until no bubbles are observed in the fluid flow.
