Interesting thing happened when I lived in the mountains in Colorado.. I guess when it gets real cold out the rodents look for a warm place. So some of them climb in between the rotor and the disc pad. My girlfriend had a Ford Escort and the brakes really squeaked for about two months. Well we took it to the Brake shop down in civilization (Ft. Collins) and the guy came into the waiting room and asked us to came take a look. There was this poor little guy (the mouse I am talking about) burnt to a crisp, with his little head sticking out just above where the rotor and the pad meet. It amazes me that it stayed there all that time, and that it withstood the immense heat that must have been generated. Basically the rest of the body was exactly where the disc meets the rotor. and that was making the squeakin' noise all that time!!! Geesh!! What a way to go hmmm??
