Trying to bleed the brakes on my 65 C60 and I am wondering what the process is for bleeding the Hydrovac system. My biggest question is how to bleed the Hydrovac. There are no bleeder screws on it anywhere. I know you start with the Hydrovac and then go furthest to closest wheel. The service manual calls for opening a manual valve but they don't get into much detail or show a picture... Haven't worked much on this type of brake system so any help would be greatly appreciated.
