    Note
    It is not necessary to bleed the brake calipers through the outer bleed valves.
    1. Flush the LH front caliper using the inner bleed valve until a noticeable reduction in air bubbles is observed.
    2. Flush the RH front caliper using the inner bleed valve until a noticeable reduction in air bubbles is observed.
    3. Bleed the LH front caliper using the inner bleed valve. See for details.
    4. Bleed the RH front caliper using the inner bleed valve. See for details.
    5. Make sure to perform the brake stiffness test. See for details.
