CT4-V Brake Vibration

[Emu1342]

They replaced the pads and rotors and the pads allegedly had an updated part number. I don’t have the car anymore so I’m not sure if it’s still a problem.

Thanks for responding. In your time left with the vehicle, i assume then, it didnt come back. Im just asking since my pads/rotors were recently replaced and i read somewhere else there may be an issue with how the wheel was milled causing this issue.

I didn’t notice it. I was never a hard driver so I assumed that was part of the problem because it seems like cars that are tracked don’t have the issue.

This appears to be the problem based on my observations over the past 8 years starting with the atsv. Cars that are driven lightly build up material on the rotors and start to feel like they are warped. The dealer then turns them and the problem goes away for a few months. Then it's back and the rotors get replaced for 2k or whatever it is.
I drive relatively hard. I bought my car used with the same symptom. After several weeks of regular driving the problem progressively lesser ed until disappeared completely to never return.

Hit the brakes and I get a lot of vibration. 5k miles on CT4-V. Visually and by touch the rotors look good, no grooves etc.
I'm thinking I have bad pads.
Unique or known issue? I'll probably schedule an Appointment with the dealer soon.

So... that CT4-V Blackwing brake vibration: my two-month old car, broken in per the owner's manual, not red-lined, never into the ABS, not tracked (yet...) and with 2,000 highway miles, has that wicked vibration. Dealer of course wants to turn the rotors, but there's no way I have "warped" anything that stout! (Ever. My average for replacing brake pads on any vehicle, since 1976, has been around 80,000 miles.) So... is it that I didn't bed the brakes properly? Or is it, really, not the brakes? I'd swear that the frequency of the vibration stays pretty much constant, regardless of vehicle speed at brake application. And it's felt more in the seat and the steering wheel than the pedal. This is one case where the car's computer "telling" on me will be to my advantage at the dealer; it knows it's never been driven or braked that hard. (Yet...)
