Note:

Even the tiniest air bubble in the circuit can cause
faulty operation (pedal failing to return properly,
crunching sound when changing gear, etc.).

Improper bleeding can result in faulty diagnostics
and unnecessary part replacements.

During every operation on the hydraulic 
clutch system, it is essential to bleed:

- between the reservoir and the bleed hole,

- between the bleed hole and the hydraulic stop.
