Jan 25, 2024 · Pulsing signals unevenly worn rotors. If your rotor isn’t perfectly flat, it doesn’t properly align with the surface of your brake pads, causing a wobbly or shuddering sensation. Uneven wear is usually caused by overheated rotors or worn out brake pads. [6]
- Vibrations When Braking. When you press on the brake pedal and feel vibrations from the brake pedal this likely means that your brake rotors are warped and need to be replaced.
- Lip Around Brake Rotor. One way to tell that your brake rotors need to be replaced is by visually inspecting them to determine if there is a lip around the edge of the brake rotor.
- Brake Rotors Have Scoring. Brake rotors should be smooth and not have many surface imperfections. If you notice that your brake rotors have scored or have grooves etched into them this can be a sign that your brake rotors need to be replaced.
- Grinding Noises When Braking. Hearing grinding noises when you are braking is definitely a bad sign and is when you need to inspect your brakes for issues.
- Squealing Noise from the Brakes. When the brake rotors get worn, it creates an uneven surface and edges on the inside and outside of the brake rotor surface.
- Vehicle Takes Longer to Stop. When the brake rotors get worn, they tend to create many uneven surfaces, which will cause the brake pads to get less “braking surface” on the brake rotor.
- Shaking steering wheel when braking. If your front brake rotors are going bad, you can often feel it in the steering wheel while braking. This can be because of rust on the brake rotors or if they got imbalanced due to overheating.
- Pulsating Brake Pedal. You can not only feel a worn brake rotor in the steering wheel. If you feel that the brake pedal is pulsating when you press the brake pedal, that might be caused by rust on the brake rotors or uneven surfaces.
Jan 4, 2016 · 1. Noisy Brakes. One of the first symptoms commonly associated with bad brake rotors is noise. If the rotors are warped (meaning not perfectly flat) or severely worn, they may produce squealing or squeaking sounds. Usually, warped rotors will produce a squeak, while severely worn rotors will produce a scraping sound.

- Look Out For Blue Rotors. Your rotors should never be blue, period! To check the color of your rotors, you will have to remove your tire completely unless you have a car with large wheels with limited spokes where the rotor is visible.
- Look Out For Grooves Or Scoring On The Rotors. Another tale-tale sign of damage to your rotors are grooves and scoring on the discs. Again to inspect, you will need to take your tire off.
- Listen For a High Pitched Screeching or Squeaking Sound. Unless you drive a Tesla or some other non-gas powered car, you should pretty much only hear the sound of your engine and tires while driving.
- The Car Takes Too Long to Break. One of the signs something isn’t working is when it stops working. Now you never want to let your rotors get to a point where they just flat out stop braking because then you are in a world of trouble.
Vibration or Pulsating Sensation: One of the most common signs of a bad rotor is a vibration or pulsating feeling in the brake pedal or steering wheel when you apply the brakes. This is typically caused by rotor disc thickness variation (DTV), where the surface of the rotor is uneven.
