Try adjusting your emergency brake cable. I am almost positive that my friend with a 99 had to do this because his car was squeaking like crazy. That was like 4 years ago though so my memory could be off ..

I also just read that it could be a "loose e-brake cable bracket"

Also, read this thread it may help.
