Brake system bleeding is working on hydraulic brake systems. This is when the brake line has air bubbles in the line. You open the bleed screw on the caliper and pump fluid through the lines until all of th bubbles are gone from the system, an air bubble will steal pressure from the brake system and prevent good operation.
