Even the smallest bubbles in the hydraulic system can cause issues with the clutch working properly.
The system must be bled in two locations:
- Between reservoir and bleed valve
- Between bleed valve and hydraulic stop
Bleeding Clutch between the reservoir and bleed valve
- Keep clutch pedal in the up position. Fill the reservoir with fluid.
- Connect transparent hose to bleed hole and to an empty container placed under the bleed hole.
- Open the bleed hole.
- The system will drain by gravity. A mixture of fluid and air drains out of the bleed hole.
- Pump the clutch pedal quickly in succession, flooring it.
- Close the bleed hole when there are no air bubbles in the fluid coming out.
- Return the clutch pedal to the up position.
Bleeding Clutch between the bleed valve and hydraulic stop
- Push pedal down as far as it can go.
- Open bleed hold, a mixture of fluid and air bubbles should come out.
- Close bleed hole.
- Return clutch pedal to the up position.
- Repeat procedure until no air bubbles are left.
- Top up fluid to max mark on reservoir. Check that the clutch system is operating correctly.
