I have changed the brakes and the rotors are not worn.What else would make it shake so bad?

So you did not replace the rotors?.. Every time you replace your pads you either need to replace the rotor or have them machined. There may be lots left on the rotors, but that doesn't mean that the disc is not warped. You also want a true surface for you break pads to break in on. Now you pad wear might be un-even.

Machine or preferably replace the rotors
Use sand paper laid on a flat surface and sand the pad untill it's even.
Make sure everything is cleaned, lubed and free.

Yes, Z is right. replace the rotors ASAP because if you put too many miles on the new pads, you will have to change them again also.
