For air/hydraulic or mechanical actuator systems:
Apply the brake pedal, then loosen the bleeder screw.
Tighten the bleeder screw 15-20 lb-ft (20-27 N•m) before
you release the brake pedal so that air is not pulled back
into the system. Repeat this procedure until no air bubbles
appear in the container of fluid when you apply the brake
pedal.
d. Check for fluid leaks.
