We have a video that shows how to bleed a brake system, click on the link provided. You will need a helper, a length of rubber tubing that will fit onto the bleeder valve and a clear plastic or glass bottle. I prefer a glass bottle because it is easier to see through glass. Start with the brake furthest from the actuator, and open the bleeder screw and allow it to remain open while your helper pumps the actuator until you see brake fluid free of air bubbles coming out of the bleeder screw. Close the bleeder screw and move to the next brake and so on until all brakes have been bled. While performing the bleeding process, monitor the fluid level in the reservoir so that more air is not pumped into the brake lines because of low fluid level. To prevent spilling brake fluid on the ground, one end of a length of plastic tubing should be placed over the end of the bleeder screw and the other end should be placed into a container so that the fluid flow can be monitored for bubbles.
