Wondering if my experience is typical.
Squeal is a function of pad and rotor interaction in my experience. Braking may be "noisier" with metallic pads, but squeal is not normal if the pads and rotor are clean and free of contaminants. Metallic pads make more noise when braking than resin, but squeal is definitely not a normal noise.
