Your Cadillac STS brake rotors are one-piece metal discs that you will find mounted on your axles near your wheels. An essential part of your disc braking system, STS brake rotors work together with your brake pads to produce friction, which is used to stop your vehicle. Your brake rotors spin in the channel of a U-shaped device known as a brake caliper.

On top of each caliper you will find a set of brake pads, one on either side of the Cadillac STS brake rotor. Each time you engage your brakes by depressing the brake pedal, the pressure from your foot is sent through lines and hoses containing hydraulic fluid to your calipers, which act as clamps to bring the brake pads into contact with the rotor simultaneously.

Friction between the metal surface of the STS brake rotors and the sandpaper-like lining of the brake pads is generated through this process, which is transmitted to your wheels and to the pavement. Since your brake rotors are subjected to this pressure each time you use your brakes, they are going to wear down over time. The rate of wear to your Cadillac STS brake rotors may be hastened through a few different conditions. If your vehicle has metallic brake pads (made with powdered copper or bronze and appearing gold in color) installed, they will cause your rotors to wear out faster. Also, your STS brake rotors can become damaged quickly if you fail to replace your soft brake pads when the lining is worn, which lets your rotors grind against the metal backing plate of the pads.Order your new STS brake rotors right here, and you can also pick up a set of fresh pads and have your auto parts delivered straight to your door.
