Just got through changing brake fluid after installing Speed Bleeders. What a great product ! 
Where have these things been all my life ? Unscrew the factory bleeder, screw in the Speed Bleeder till it bottoms, open 1/4 turn, hook up a clear drain hose to a jar and pump the brakes till it runs clear, tighten Speed Bleeder - Done!
Got mine at NAPA, part # 675-1565 fit drums and calipers.
