Perhaps someone can tell me how much of an issue/problem the attached images are. I will readily admit brakes are a part of the car I have not often worked on, so I am not sure how concerned to be.
The two shots are of the rear rotors on my wife's car, which I am driving while she is out of town. I noticed one is smooth, like the ones on my car and her front rotors (and how I expect rotors to be) and the other is grooved enough for rust to develop and not be removed by the pads during normal use(these shot was taken immediately after driving).
I am confident that I have the skill set needed to do, or learn to do, the work needed. But, I don't have the experience needed to determine if this is within the normal range, or it it is time to replace the rotor and pads (as far as I know the rotors are original, so they have 145,000 miles on them over 11 years).
If work needs to be done, I can handle it at my own pace. Rather than learning at the state inspection in a few months and paying the gotcha inspection prices.
