Your brakes are one of the most important parts of your car because they allow you to stop and keep you safe. If you notice there are some issues with them, it could be due to bad or worn rotors. Here are some signs that your rotors could be bad and may need to be replaced. A Mesa, AZ auto repair shop can help you with all your repair needs.

Metal Noises

It’s common to interpret brake noise as a sign of a bad rotor. This isn’t always true. It is important to be able to tell the difference between a warped rotor and moisture- accumulate sound caused by a vehicle left in the open overnight. It is actually normal to hear this last type of sound after driving for a while. When the weather is snowy, rainy, or humid, keeping your car indoors is another simple way to prevent this problem. The sound of squealing indicates a worn brake pad or worn brakes. A squealing or squeaking sound is caused when the brake pad wear indicator strikes the brake rotor. Another cause could be a dirty vehicle or brake dust buildup.


In order to slow or stop your vehicle, your brake pads contact the smooth, flat surface of the rotors. The friction created by these brake rotors causes them to become hot, and they also receive considerable amounts of pressure, which results in the rotors becoming bent, uneven, or warped over time. A rotor and caliper are structurally attached to the same spindle that connects the wheels. As a result, if the rotors lose their smoothness, the feeling of unevenness or vibration is transmitted through the spindle and eventually makes its way to the steering wheel. Thus, the steering will not operate as smoothly as it used to when the brake pads and rotors are in good shape.

A blue mark on your rotor typically precedes an issue with the brakes such as rotor cracks, faulty calipers, broken brake shoes, and uneven brake pad wear. This discoloration is caused by too much heat resulting from riding the brakes, incorrectly aligned brake calipers, or an insufficient heat dissipation from the stock brake components. The brake system may not be engaged, but the pressure is being exerted on the brake pads. If you see blue rotors on your car, you should do a brake inspection. You should find out exactly which of the components mentioned above is defective or needs to be replaced right away in order to avoid more serious braking system problems. Brake pads should be replaced with ceramic ones to improve heat dissipation and discolored rotors should be replaced with drilled-through slotted rotors.
