Why are my brake rotors rusted?
Why do my rotors rust? This boils down to the material of the rotor. Unless you have an exotic car with carbon-ceramic brakes, then your rotors are most likely made out of cast iron, which is prone to rust. Iron oxidizes easily, and rust will form on the surface of the discs if they are exposed to water or moisture.
What happens if you don’t replace worn rotors?
Brake rotor unevenness leads to pad wear, and if unchecked, pulsation with high-speed braking. This means the tires wobble and vibrate, leading to a jerky steering column and to anti-lock brake system failure.
Are there any brake rotors that are rusted?
The rotors are in fact quite rusted, however, there is no rust on the actual surface that touches the pads. Running my fingers over the surface of the rotors, there does not appear to be any buildup of brake pad deposits and the surface is relatively smooth.
When do you know your brake rotors are worn?
Over time a lip will form on the edge of the brake rotor as the brake pads start to wear into the brake rotor. While a large groove or lip at the outer most edge of the brake rotor is a sign that the brake rotor is worn, it may not need to be replaced at this point.
Can a car not pass inspection due to rust on rotors?
The car brakes fine, there’s no unusual noise or vibration or anything. This seems a bit suspicious to me; I’ve never had a car not pass inspection due to rust on the rotors, and the car isn’t even that old. Does this seem legitimate, or are they trying to get some extra money out of me?
Why are my brake pads and rotors not working?
If your brake pads and brake rotors become glazed over this can cause your brakes to not work as effectively as they used to.
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 causes a car brake rotor to Pitt?
As AMPM Automotive Repair describes it, “ Rust on the brake rotor can cause pitting. The surface of the rotor should be smooth so it can have full contact with the brake pads. Brake pads must be the exact size to perfectly match the rotor. The more contact the brake pad has with the rotor, the more braking power your vehicle will have.
