How does a serpentine belt get damaged?
Serpentine belts can fail in a few different ways. This is usually the result of a belt in poor condition, or a problem with one of the accessory components being driven by the belt. A failed bearing in a pulley being driven by the serpentine belt will also cause the belt to break.
What to do if your brake rotors are worn?

What makes a rotor make or break a rotor?
Just about every rotor is made of cast iron, but what can make or break a rotor are ingredients like carbon, silica and pearlite. Also, how a rotor is cast and cooled can determine its final properties. This is called the science of metallurgy. Ensuring that a rotor has the right metallurgy costs the manufacturer time and money.
How can I tell if my serpentine belt is bad?
So, if it’s worn out, it will start slipping over the alternator pulley and the alternator won’t be able to produce enough electric power. This symptom of a serpentine belt problem is notorious for being hard to recognize. In most cases, there will be no sounds or visible symptoms.

When do brake rotors need to be replaced?
Since rotors work to slow the vehicle by using friction from direct contact with the brake pads, they do wear out over time and will eventually need to be replaced. When rotors have a problem, they usually produce any of the following 4 symptoms that alert the driver they require attention. 1. Noisy Brakes
Why are my brake rotors shaped like a dish?
1 . Dishing. As the name implies, rotors can wear unevenly in such a way that they become shaped like a dish. This is generally undetectable at a glance, although you might feel a lip on the outer edge of your rotor.
How are brake rotors attached to the wheel?
Brake rotors are bolted directly to the wheel hub, so they spin in direct relation to wheel speed. When the brake pedal is depressed, the calipers squeeze the brake pads against the spinning rotors to slow and stop the wheels and the vehicle.
