Works fine for 8 months and about 12k miles the steering … Bought from Amazon and installed with a set of Akebono ACT-787 ProACT ceramic pads on a 2012 Accord EXL. Works fine for 8 months and about 12k miles the steering wheel vibrates when braking at highway speed, two months later at 15k miles the shaking got worse to a point that driving the car was not pleasant and feel safe. I thought the rotor most likely warped.This was the first aftermarket rotors and pads I ever used for the past 30 years. The original rotors on the Accord warped…
Horrible vibrations in less than two years of average driving; terrible customer support. I read the great reviews when I bought these two years ago. I installed them and looked forward to a long-lasting high quality replacement part. Our van had over 100,000 miles on it and still had the original OEM Honda rotors when I put these on. A few months ago I started to get vibrations when braking and now the vibrations are so bad I don’t feel safe, especially if I needed to stop suddenly at higher speeds. I am very disappointed in these rotors.UPDATE: I’ve waited three weeks for…

Called couple weeks later and talk to someone who again took my information for warranty people to be called back. Again, two weeks has passed and still not return phone calls. Stay away from those rotors as company doesn’t stay behind its products.UPDATE: Called again, the customer service updated my initial ticket and of course two weeks have passed without a call back…
