Default Rotor wear issue

Hi Everyone,

I replaced the new OEM rotors and brake pads over the weekend.

It seems like the rotor did not wear evenly. I hear the noise when I lift off the gas pedal.

I can't tell this is the problem with brake fluid, it is time to flush or sticky caliper pistons.

Please advise.

Make sure that the pads are installed properly. You can ask somebody to press the brake pedal while you are watching if the pads are parallel to the rotor surface.

Yes, I already removed and carefully reinstalled, but the noise is still there. I can hear really loud in the highway.

Here is how the previous rotor looks like before I replaced it.

If somebody presses the brake pedal for you and you observe what happens to the pads. It might provide some clues regarding the issue.
