Well when I bought my car, the brakes needed to be bleed soo bad that only way to make the car(1970 Chevelle) come to a stop was pretty much shift into neutral. My dad and I bleed the front brakes and that seemed to help some, but when we went to the back, no air came out. There still isn't enough pressure. We were thinking that there was either an air lock in it or the line is crushed. Any suggestions on what we can do to fix it?

I would look for crunched hard lines, brittle rubber lines that are cracked and leaking, check the connection points to see if they're leaking, and also be sure the wheel cylinders aren't leaking.

Other thing, while bleeding the brakes it best to bleed from the furthest from the master cylinder to the closest. So passenger rear is first, drivers rear is next, then passenger front, and finish up with the drivers side front.

Good advice from Steve. You might check the rubber line to the rear brakes, loosen the hard line where it enters the fitting for the rear rubber line and see if you get fluid there when someone pumps the brakes and if you do, the rubber line may be the culprit. I would replace all the rubber lines if they are original.
