A 5/16-inch box end wrench was used to open and close the caliper bleeder valve. As the brake-pedal was pumped three of four times, it built up pressure in the brake line and caliper. The valve was opened, which released fluid and any trapped air into the submerged plastic tube inside the quarter-filled catch bottle. This was repeated until the brake pedal was firm and all of the air bubbles were eliminated from inside of the brake line and caliper.
