As part of my rebuild, I have replaced most of the brake system. I ran all new metal lines(Some high points, not sure if that is a problem), all new rubber lines, new dual master cylinder with booster, rebuilt all 4 drums, new shoes on rear, adjusted all shoes.
Now I filled the master cylinder, running a line back up into the top, bleeding it. All air is out of both banks, and just pumps fluid now. Plugging both ports with caps, brake petal is firm and can hardly be moved, so the master cylinder must be fine. Connecting the lines, and trying to pump, it goes almost to the floor. Bleeding the rear, I get alot of air out, pedal is now about 3 inches off floor. Trying to bleed front brakes, I get a few little bubbles on first try, then nothing. No matter what I do, I get no fluid or anything from the front bleed values.
I have spend hours(20+) on this, and am frustrated to heck and back. Only thing I can think of is the metal lines are higher than the master cylinder in places causing air to get stuck? Some have also said that taking the MC off the truck and bleeding it will help, but I don't see what that would matter taking the info above into account.
Please please, any suggestions before I tow it to a pro shop and loose my entire budget for this year???...!!!
