I question the information on this website due to their insistence that warped rotors are common, which they are not. However, is the following true?
Place for Brakes FAQ
Q: Are metallic pads damaging to rotors?
A: Yes, they can be. If you examine a cheaply made metallic pad you can see and feel the size of wire and steel particles in the mix on the pad. Then you compare it to a premium brake pad and the face of the pad is smooth and uniform in the mixture. Which in turn keeps the face of the rotor smooth and does not excessively ware down the rotor.
Should I change the pads when I replace the rotors on my ’94 Grand Am? There is > 50% pad thickness remaining. There is substantial vibration under braking & the grooves in the rotor are clearly visible & can be easily felt. I haven't looked at the pads yet for cracks which would obviously mean replacement.
BTW, I was curious about OEM rotors from GM. They are $91 each at the local dealership (~$50 online) & made in China. I was quite surprised at that combination. ATE PremiumOne Slotted rotor, Centric 120.62034, Power Slot 126.62034SR/SL, etc. – all China. I didn’t want cross-drilled, slotted style. I’m probably going with EBC (made in UK) UPR7054 solid vented rotors ~$75-90/set (OEM replacement) since I can’t come up with much information on the Brembo 27029 (made in???) or even 67029 (made in???) solid vented rotors (OEM replacement).
On the opposite end, I have never changed or “turned” the rotors on my ’02 Accord with new pads (couple sets). I see that claimed quite frequently as well including at the EBC website. I imagine that a great portion of that recommendation is based upon fewer complaints, etc. & no true defined need in every case.
