Russell Brake & Clutch Speed Bleeder With 10mm x 1.0 Thread, 35mm Overall Length

Was not "perfect fit " at all as described by advance auto

These bleeders allow you to leave the bleeder open while you pump the brake pedal to force fluid through the brake line. The check valve in the bleeder prevents air from entering the brake line when you release the brake pedal. However, it is not entirely a 1 man process. You still need someone to watch the bleeder to verify when all the air bubbles are out of the wheel you are bleeding. Also, the pressure required to push the check ball open is aquired easily by stepping on the pedal but you may not create enough pressure using the pressurized bleeding systems that force fluid through the master cylinder. Typically those systems use 10 - 15 pounds of pressure that may not be enough to open the spring loaded check ball in the bleeder screw. I have not tried vacuum bleeding with this style bleeder screw but vacuum bleeders utilize 10 pounds of pressure also.
