Bleeding brakes is no big secret, but you have to do it in the correct order. First start by bleeding your master cylinder, and then have someone pump the brakes slowly to prevent tiny air bubbles in the system. Ask the person pumping to hold pressure on the brake pedal so you can crack the brake bleeders on the furthest point from the master cylinder (right rear caliper). Then close the brake caliper bleeder screw and the brake pedal can be pumped up for pressure again, continue several times until no air comes out of the caliper. Then continue the process on to the left rear, front right and front left calipers until brakes hold pressure. Wilwood calipers have two brake bleeders on top of the calipers and Wilwood suggest that the inner bleeder then the outer bleeder until air is out of both.
