I had just changed my rotors and pads to brembo slotted with repco metal master about 5 months ago (or approx 6k miles). But now, i think the rotors are warped ? i mean, how can i be sure.... like i said, i just changed it. And I dont drive the car often but it had some auto-x time after the change. Could it be that its already warped ? I heard some rumor that repco metal master DO warp up rotors. And I do have brake air induct for the brakes. Any help would be appriciated.
