I work at an auto parts store, we also sell “one man bleeder kits.” This post interest me since I just got a 1999 Blazer myself.
In 1964, that meant pulling a vacuum line from a neighbor's car, putting some brake fluid in a baby food jar, connecting the tubing to the brake bleed valve with the other end under the level of the brake fluid in the baby-food jar, and when the bubbles stopped coming out, the air was out. Close the valve, and send your brother on a test drive.
Have they improved that procedure? Or just buffed up the advertising?
