Will,
I having trouble with "fluid going the wrong way". If you were able to bleed the brakes, the fluid is going to the wheel cylinders and they should work. Go back and check the installation of the lines, double check the adjustment, and re-bleed the brakes. The installlation of a dual mc & booster is fairly straight foreward. You normally don't need a proportioning valve like with disc brakes so everything should be OK.
