I am trying to finish up a nine year project. I am looking for some helpful tips to get this monster"s brakes bled. It has a new master, 4 new rear wheel cylinders, 2 good rebuilt front wheel cylinders, rebuilt hydrovac, new brake lines and hoses. all visable leaks have been run down and corrected. I get a a firm peddle until I start it and the hydrovac comes on, then the peddle goes to the floor . What is up, am I doing some thing wrong here? I bleed the hydrovac first, then the front, then the rear. Help! Many Thanks Joe Newton
