i had no idea this had been going on for some time, thanks for clearing that up.
As someone who has been here at USMB for a long time - yes, this is "normal", LOL. That said, no one typically takes things too "personally", altho there have been a couple of times when things got a little heated.
For me, personally, it is far easier & more cost effective to simply replace worn out/bad rotors. I live out in the boonies, and machine shops around here tend to be rather expensive - plus the time & cost of traveling back and forth... If the rotor is just lightly grooved, chances are I will leave it alone... deeply grooved, it will most likely get replaced.
The rotor i shared the picture of was from my 95 Legacy - the car had been somewhat abused by a teenager - tranny was shot - and then it sat for a while before we purchased it (yes, we got it cheap) Those rotors were a pretty extreme case, however, with the braking surface flaking off.
Planning ahead for DIY work is just a good idea. Ordering parts in advance makes life a lot easier once you get going on the job. the absolute nearest parts store for me is a 20 minute drive, one way... and that is a small town store, so them having what I need/want is a shot in the dark (yes, I usually call ahead to avoid wasting gas). Next nearest, larger store is a half hour, one way... so yeah.. Rock Auto, and other online retailers, get a decent share of my business as they ship my parts directly to my door - I don't have to go anywhere.
