After replacing the master cylinder, front brake pads, rear brake shoes, and front brake hoses, and front brake calipers, the front disc brakes will not release when I take my foot off of the brake pedal. The pads will remain "engaged" until I open the bleeder valve. They will stay "un-engaged" until I step on the brakes again, then, you guessed it, they stay engaged again until I open the bleeder valve.

Only a few thigs will do it, pushrod is not set right, that the one on the booster, or it needs brake hoses, or, if the fluid is contaminated with oil...draw a small amount of the brake fluid out of the master, swirl it in a cup of water, should be milky white. NO oil beads. Also check in back, are you getting fluid out of the rears? If there is a hieght sensing valve back there, it could need adjusting...
