I have brake pedal pulsation due to warped front rotors. Brake pads have a lot of life left. Should the pads be replaced when the rotors are replaced?
Should good brake pads be replaced when warped rotors are replaced? on 2002 Ford Explorer
If I was doing the repair, I would, as most likely you will have braking issues if you just replace the rotors. The rotors should have been replaced or machined the last time the brakes were replaced if they have warped already. Pads aren't expensive, and since you're in there to replace the rotors, it makes sense to put in new pads. The old pads are adjusted to the old surface, and may not work as well.
Weighing in - I agree with the scuffing of the pads IF they are still at 8mm + in thickness. Below that, it's better to be proactive and replace them.
Thank you for your quick and insightful responses. Not yet knowing the actual thickness of the pads, it probably makes sense to also replace them since (as ryans93 has said), they are not very expensive and the system will already be disassembled. Thank you all.
Ryans93 is right. However, it may be possible to scuff the pads if they have not been on for long.
