What type of pads and rotors are you putting on? You may aleady know that different brands a brake pads are made out of different components. Many life time warranty brake pads use harder components that often cause squeeling and squeeking when you use the brakes. THey come and go, sometimes lasting months at a time, until that area of the pad is warn down enough that the squeeling stops. It the squeeling is persistant, even when not braking, you may have an entirly different problem. Hope this helps!
