Make bleeding the brakes not only a one-man job, but easy to boot. The power bleeder works just like professional pressure bleeders. A tank containing brake fluid is attached to the brake system via a special adapter; the tank is pressurized with a few pumps. This pressurization pushes fresh brake fluid through the entire system allowing one person to bleed the air out of the system at the brake calipers via the bleeder valves. The Power bleeder is a simple & effective tool you don’t know how you lived without.
