What was the condition of the rotors such as surface rust, pitting, grooves etc... prior to installing the Alpha pads? Did you experience any other issues / any squealing or other noise at any stage with the Alpha pads? Did you get the brake pads wet like you ride in the rain. Did you bleed your brakes & maybe some brake fluid or any other contaminants on the rotors or the pads. Did you use any wheel cleaner / car wash etc...etc... recently?
