    Why does the dust caps don't keep on the bleeder valves?

    When the caps are placed, the enclosed air is pressed into the upper part of the valve. If liquid is still present, an overpressure develops and the caps fall off. If you have our small bleeding deivce, you can simply suck the liquid out or vacuum it with a paper towel. Then keep the dust caps safe.
