Quote: Something that is looking to be an issue. The back brake rotor doesn't look so good. It is grooved, a little rusty from sitting. And what is getting my attention is delaminating in a few spots. And a bit noisy on braking. Can I sand the rotor or do I just need to change it out. I need new tires so it would be great to do this at the same time if needed.
I suggest measuring the rotor width to dertermine if it is still within spec; what is the remaining brake pad thickness? Without knowing that, it's hard to say.
You can clean up the "rust" with some steel wool & brake cleaner.
Given that this started as a carb thread & has now morphed into brakes you might want to start another thread focused on brakes.
