I am using a mighty vacuum pump to bleed the brakes on my 1992 cadillac deville. Do I have to depressurize the system. I have anti lock brakes. It says to disconect the negative battery cable leave the ignition off and to pump the brakes 25-40 times. If I have to depressurize the system is that all I need to do. Thanks.
