4. Move pedal extremely slowly to the "Pedal fully depressed" position. When doing so, guide the pedal by hand so that it does not move forward abruptly.
5. Allow the brake fluid to rinse through for 30 seconds.
6. Afterwards, activate complete pedal travel manually very slowly for a further 60 seconds. After about 10 to 15 pedal strokes, leave the pedal in its normal position. Once this filling period has elapsed, check that no more bubbles appear at the bleeder valve (use a collecting bottle with transparent hose). Then close the bleeder valve.
7. Switch off and disconnect the bleeding device. Check the brake fluid level. It should not be above the MAX. mark.
8. Activate the clutch pedal slowly, five times.
9. Fit the cover over the brake fluid reservoir.
