5. Move the pedal very slowly into the "Pedal fully depressed" position. When doing so, guide the pedal by hand so that it does not move forward abruptly.
6. Allow the brake fluid to flush through for 30 seconds.
7. Afterwards, actuate the pedal fully very slowly with your hand for a further 60 seconds.

   After about 10 to 15 pedal strokes, leave the pedal at its normal position. Once this filling period has elapsed, check that no more bubbles appear at the bleeder valve.

   Only then should you close the bleeder valve and tighten it to → Tightening Torque: 5 Nm (3.5 ft. lbs.) +/-1 Nm (+/-0.5 ft. lbs.)
