Step two – attaching the bleed funnel

Pour a small amount of mineral fluid into the supplied plastic funnel. Remove the o-ring that seals the system and gently screw the funnel into the top of the lever. When attached, remove the plunger from the funnel, allowing fluid into the system.

More importantly, using the funnel and its contents ensures that only fluid enters the system, and not air. Additionally, escaping air will be visible in bubbles in the fluid in the funnel.
