Signs of Bad Brake Rotors

a8OUrxThere a few different ways to tell if your brake rotors are bad. If you believe that they are bad, don’t hesitate to contact us here at Autoworks to have one of our mechanics check them out and decide whether or not they need to be replaced. It is important that your brakes are always working properly, as faulty brakes can present hazards and put you at risk of an accident. Here are a few signs of bad brake rotors.

Pulsating Brakes

One sign that your brake rotors are bad is if they begin to pulsate when you push the brake pedal. You get the sensation that you are pumping the brakes when you are not.

Grinding Noise

Another sign your brake rotors are bad is when you hear a low grinding noise while pushing on the brake pedal. When the brake rotors get worse this grinding noise can increasingly get louder.

Ridges on Rotor

The grinding noise starts when the brake pedals wear out and the metal screws rub against the rotors. Ridges begin to form on the rotors, similar to the grooves on the edge of a quarter, only larger.

Braking

If your brake rotors are bad, sometimes you will hear a low grinding noise even when you are not pushing on the brake pedal, and the noise escalates when you push the pedal.

Stop Abruptly

Instead of a smooth stop, you car will come to an abrupt halt when you push on the brake pedal, as it begins to grind. The screws from the worn out brake pedals push into the rotors and make it seem as though the emergency brake is on.

Visible Ridges

If your brake rotors are bad, you will be able to inspect through the tire at the rotor and see the ridges that have formed. A tool called a micrometer can be used to measure the thickness of the groove in the brake rotor. If a rotor is not completely worn out, the grooves can be removed by a mechanic by machining the rotors. If the rotors are too thin they cannot be machined because they could pose a safety risk.
