Is it bad to have rust on rotors?
There is a certain thickness that all rotors must be at in order to still be considered safe. Rust on rotors usually isn’t a problem unless it is causing issues with your braking. Most times, a little rust on rotors will only wear brake pads a little differently.
What to do if your brake rotors are bad?
If you’ve had any brake system or suspension work performed on your car there is a chance that grease or oil got onto your brake rotor making it slippery. The best way to remove grease or oil from your brake rotors is by using brake cleaner and a clean rag to clean your brake rotor surface.
How can you tell if your brake rotors are warped?
Brake rotors by design will be flat and smooth. Usually, with warped brake rotors, you can’t tell with the naked eye that they are warped. The easiest way to tell if your brake pads are warped is to feel the brake pedal for vibrations or pulses when braking.
Is it true that turn rotors are true?
The only real case to “turn” rotors true is if you have some 50’s classic (Buick with aluminum finned drums anyone?), or a large truck, wherein replacement rotors are exorbitantly expensive. So, to summarize, if you brought this car to me, and you had decent pad thickness, I’m not in the business of ripping you off, so I would send you on your way.

What’s the best way to remove rust from a brake rotor?
Put down a tray to catch any runoff, then spray the rotor with brake cleaner. Let the rotor dry, then wipe it with a clean rag (no oil on the rag). If some rust remains, apply more brake cleaner and work the surface with steel wool or a wire brush. Wipe off the rotor and finish with a final shot of cleaner.
When do brake rotors really need to be replaced?
I need to replace my rear brake pads. A mechanic suggested I also replace my rotors because they are rusted around the edges. The rotors are in fact quite rusted, however, there is no rust on the actual surface that touches the pads.
What happens if the rotors are missing on a car?
Missing rotor material means the pistons travel out beyond what they were designed to, which can damage seals, and even sieze/ruin a caliper. I’m just summarizing what has already been said by some very erudite folks and throwing on my own never-humble spin.
