Bee's nest hiding under the dashboard Rusty Brake Rotor  See The Difference between new and old brake rotors: Below are pictures of two brake rotors for a 2000 ford crown Victoria. One is an original equipment ford rotor that has been installed on the car for about 10 years ago. The other is a New Old Stock (NOS) rotor that was produced about 10 years ago and has been stored in a humidity controlled environment since manufacture. See the picture below and that will say why your brake rotors needs to be inspected and replaced if its worn out and rusty: These two rotors were made using the same castings. But do you notice how the rotor on the right looks very different near the cooling vanes due to all the thick rust scale?

This design uses pistons on just one side of the brake caliper. Brake calipers are a crucial part of the braking system of any vehicle, as they perform the mechanical aspect of the braking action. Properly understanding brake calipers, their function and operation, helps you to identify issues when the brakes do not work correctly. While basi...
