Using a 3/8" wrench with your left hand, open the bleed valve on the front brake cylinder.

The built-up pressure in the lines will force some of the brake fluid out of the lines.

Continue to force more brake fluid out of the brake lines by depressing the front brake lever with your right hand.

Once the brake lever is completely depressed, quickly close the bleed valve, making sure that no air bubbles enter into the brake lines.
