6 install the proportioning valve e. The closer the proportioning valve is to the air compressor, the less air line will have to be routed between them later. The proportioning valve must be mounted with the bleeder valve pointing up. The valve will not- bleed the brake system if it is not pointing ...

One-person methods continued from previous page container to a hand-held pump. When the bleeder valve is opened, the pump draws the brake fluid and air bubbles out of the brake line and into the container. If you use this method, follow the same sequence of wheel cylinders as described in the tradit...
