Just got my ProMotive power bleeder today with the 3-prong adaptor, Can someone tell me: 1) How much pressure is required for our cars. 2) Which wheel to start on & sequence for the next three. 3) Does car have to be level. 4) Anything else I was done with the brakes yesterday but, couldn't drive it as pedal felt very soft so, I'm trying to get it done tonight. Thanks, Ed '90 195K
