Photo below is the rear driver side rotor. All rotors have the same "wavey" pattern. The grooves are "in line" with the hole; it's as if dust/FOD got trapped between the pad and rotor through the hole and it's left a groove in the rotor. This is my first car equipped with cross drilled rotors, so I'm not sure if this is considered normal wear. All pads have 6+mm of pad material left and rotors have a small lip on the O.D. No vibration or anything that would cause alarm. Just an inquiring mind.

Re: Questionable Rotor Wear
Looks about correct for that rotor type. I wouldn't worry about it.
Just when its time to do the pads, do the rotors as well. I see it at work all the time. Even if they are within measurement spec, replace. Wont give a "perfect" contact with the new pads.

Re: Questionable Rotor Wear
Totally normal. Replace rotors when out of spec (2mm or more of wear measured in few spots on the rotor).

Re: Questionable Rotor Wear
Yes! Don't replace them because your pads are gone. Your rotors will last longer than a set of pads. Check the thickness, proceed accordingly.trailbrake996 wrote: ↑Wed Jan 31, 2018 8:43 am Totally normal. Replace rotors when out of spec (2mm or more of wear measured in few spots on the rotor).

Re: Questionable Rotor Wear
Was going to do a pad replacement when doing my next oil change. What is the spec rotor thickness?
