Bad Brake Rotors Symptoms

Every motorist should ensure that they have working brakes so that they can prevent accidents and injuries. Similar to any other car component, brake rotors also wear out and should need to be replaced. There are various signs that can alert you before it’s too late. One of the simplest ways to know if your brake rotors are bad is by having a regular service. Visiting a mechanic from time-to-time to check the overall state of your car is a really crucial thing. In this article, we’ve discussed below some of the common signs that will tell you that you need to replace your brake rotors.

Vibration from the brakes

If you feel excessive vibration or pulsating coming from the brakes, this is a sign of bad brake rotors. Worn out or warped rotors may vibrate on an irregular basis and lead to vibrations that can be felt in the pedal, and at times via the car’s chassis. Bad rotors may as well produce a pulsating feel that will be felt in the pedal when the brakes are enforced.

Noisy brakes

This is among the main signs of a warped or bad brake rotor. So, when the brakes are noisy, you should check your brake rotors. Warped out or worn out rotors may produce a squeaking or squealing noise. Normally, worn out rotors will produce a squeak, and severely warped rotors will produce a scraping sound. Nevertheless, the squealing noise would emanate from the worn-out brake pads too.

Grooves or score marks on the rotor

The last sign of a bad rotor on our list is scoring or grooves on the face of the rotor. After a particular period, grooves or scoring marks can develop on the rotor from repeated contact with the brake pads. Grooves and scoring in a rotor can take away from its capacity to slow the car, and also cause vibration and pulsating that can be noticed in the pedal. These should be replaced instantly.


When you realize that your brake rotors are bad, you should see a mechanic right away and acquire new ones for replacement. Brake rotors are an important part of the braking system and thus they should be in a good state all the time. Bad brakes can lead to accidents. So, if you note one of the above signs, you should check your rotors and if they are bad replace them right away.
