Rotors: machine vs. brake vs. leave as is?
Hey all,
About to bring my car in to get the rear pads replaced, and although I've Googled this to death, wanted some thoughts from the forum on when to machine vs. replace the rotors (or even leave them as is).
Here's what I've found:
1) leave them as is: ok as long as grooving is minimal, more than minimum thickness is still there, and no vibrations, pulsing, or noise from brakes. Then, make sure to properly bed new pads.
2) machine: ok as long as minimum thickness is still there after machining
3) replace: do this to ensure proper mating b/w pads and rotors
The rotors are expensive at $250 for the pair so I want to ensure it's absolutely necessary at this point - see pics below. The rotors have never been replaced but this is the 2nd time the rear pads have been replaced. First time was at 30k km, car is now at 75k km.
Thank you!

Actually, your rotors don't look that great from those photos. do you live in the rust belt?
