I was talking to a fellow member and he told me I needed to charge my master cylinder. He told me to fill it with fluid and then pump it to get out all the air, recycling the fluid. I was planning on bleeding the brakes when I am ready to put the fluid in but wondered if I needed to take out my new master cylinder and do what he recommended. It seems to me that pumping the brakes, relieving the pressure (air) would take care of the air in the new lines. I am looking for advice before I take out the master cylinder and doing what this fellow member told me. Thanks.
