Brakes going soft after raising car?

So I've been messing with my front alignment and with my transmission front band adjustment which has required me to raise the car multiple times. This has led to my brakes getting soft, brakes dragging and feels like air in the lines. Everything in the brake system is brand new... except for the proportioning valve, I traded my dist block for the prop valve. I built all new brake lines and the car was stopping on a dime afterwards, but now it is having the above problem.

I havent had time to check everything out under the car as I noticed it last Sunday and have been busy with school, but any advice on what I should look at first before rebleeding them? Has anyone ever heard of or had this kind of problem before?

Pic for attention...
