They dont squeak. I did take them apart and did exactly that. Its like a creak. Such as when you step on a wood floor. Only in theory but not in sound. It sounds as though the metal is flexing back and forth. I dont have the least idea what the heck it could be.
get the car in the air and check the dust shield, lower ball joints, lower control arm bushings and make sure all the bolts on the brakes are properly torqued
nothing in the actual braking system that i know of will cause a "creak" noise
Funny thing is that the noise is made. When my car is warm at a stop. I will mash the pedal and it will make the creak noise. The noise is really close to the wheel so I know that it is the brakes. I torqued the brakes to a tight fitting. I couldnt measure since my torque wrench is too big. Could the torque be messing them up. This happened since more than a year that I changed pads and torqued it.
