Question:

I own a 96 Chevy Cavalier and the breaks are bad, the pads are still good, we removed the air from the line, and it has great vacuum what else could be wrong?

Answer:

The master cylinder could be bad. How did you remove the air from the lines? With modern ABS systems, its usually best to use a pressurized or vacuum bleeder to make sure all the air is out. The old crack the bleeder and have a buddy push the pedal does not work as well as it used to. I would take it to a shop that has the proper bleeding equipment and have them get all the air out, if its still bad, then its more than likely the master cylinder.
