Squealing Brakes

[Dupo]

My front brakes are squealing like crazy. Ive redone the brakes 5x now and i still have the problem.

1. Put new brakes on -> squealed shortly after putting them on
2. Removed brakes, brake cleaned everything, brake lubed and also used brake 'goop' (the orange brake stuff to reduce vibration) -> squealed again
3. Removed again, relubed and regooped. -> squealed after a day
4. Removed once again, same as above. Used more goop this time. -> lasted 2 days.
5. Removed again, this time replacing the plastic backings on the brake pads and regooping. -> lasted 2 days again.

:evil: Any ideas?

The rotor is smooth and everything seems to be working fine. I dont get it.
