What do glazed rotors sound like

While this symptom can indicate wear, it remains more commonly associated with a warped rotor. Some vehicle manufacturers even require that you replace your rotors rather than resurface them.

Otherwise, most industry experts suggest that you should replace them every K miles. In any case, if the rotors are beyond resurfacing, replacement is your only option. Surface finish is crucial to proper vehicle braking and pad life and should always be part of a complete brake job.

Resurfacing Your Rotors Sometimes your rotors may need to be resurfaced because they have worn unevenly, warped from heat, or become damaged by worn brake pads or pitted from corrosion or rust.

How much do rotors cost? Do new rotors make noise? Can bad rotors cause squeaking? A shiny or crystallized look to the brake pad is also an indication that it has glazed over.

Listen for a squeaking or squealing sound when you press down on the brakes. This is one of the most common signs that the brakes are smooth due to overheating and have become glazed. Listen for a continuous scratching or squeaking sound even when you don't press on the brakes. In this case, the brake pad may be consistently dragging across the rotor while you're driving. This continuous friction causes overheating that results in a glazed brake pad.

Test your vehicle's stopping power, when driving, in a safe location, such as an empty parking lot. Imagine this scenario: You pick up your car from the repair shop, excited to see how it feels with new brakes on the front and back wheels. You start wondering if the mechanic actually did the work and questioning if he did it right. Answering this question is a bit more complicated than a simple yes or no. Squeaking or noisy brakes could be due to several reasons. In rural areas and homes where driveways are covered by large trees, it is not uncommon for your wheels to pick up a tiny twig, a small stone, an acorn, or other debris, which can cause your vehicle to make the most annoying noises.

If the object is something soft, such as a twig, it will wear down quickly and be thrown out of the wheel very shortly. A stone, however, can cause real damage. Your grandfather might tell you that he remembers a time when brake pads and shoes were made with asbestos—and he wishes they still were! Those old school brake pads rarely squeaked, but they also posed serious health hazards to the mechanics who unwittingly breathed in the brake dust laden with asbestos. Many brake pads today are made of ceramic, which are great for how long they last and how well they stop the vehicle.

But they can also cause a great deal of noise on your cast iron rotors. These tend to be a bit quieter than ceramic pads. Please note: This is likely to involve an additional cost. If your brakes only seem to squeak in the morning or when it rains or is foggy, it could be due to the moisture in the air. This can cause a very thin layer of rust to build up on the rotors, which will cause the pads to squeak temporarily until they warm up and you wear off the rust by stopping a few times.

As your brake pads wear, the brake rotor or disc can develop grooves, glazing or uneven wear. Whenever the brake pads are replaced, the brake rotors need to be removed, measured, and machined or replaced. This will ensure the surface is completely smooth and flat.
