One of the rotors began to deform one month after installation. Not what I expected. Checked the Revain website for warranty options and the rope will expire in 30 days. I installed them after purchasing Power Stop (Z23-756) Z23 Evolution Sport brake pads. Installation was easy and the front brake calipers and brake lines were also replaced. After about 3 1/2 weeks of driving under normal conditions, I noticed a slight pulsation when braking. After raising the car, the tire spun rapidly and I could immediately tell the bump was slowing down in one spot. Upon visual inspection, I saw that the rotor deformed slightly as I turned it. If Power Stop can contact me for a solution I would be very grateful.
