I don't know what I am doing wrong but I think something ain't right.
I replaced the M/C (which I bench bled), all the front lines for my 77' front end (vacuum boost) and left the rear lines, but they had run dry from the previous M/C. I also invested in the nifty Speedbleeders so I could bleed it myself.
I bled in the order everyone says, furthest away from the M/C to the closest, and after passing a two quarts of brake fluid I still am getting bubbles in the rear and front. There are no leaks anywhere and I can see that the bubbles are coming out of the speedbleeders and because they are supposed to be a "one way valve" I am assuming they are not drawing in the air.
Is it possible that I have that much air in the lines (new lines in the front, dry in the rear) that I need to run that much fluid through?
I also saw a thread about the rear proportioning valve- pretty certain it's not stock but do I need to do something with that before I bleed the system?
