What Are Brake Rotors?

OEM rotor GM

A brake rotor is also called a brake disc. It looks like a metal frisbee with 5 or 6 holes in the middle. Your car has either two or four brake rotors. The rotors work with the calipers and brake pads to stop your Cadillac within seconds. Here’s an overview of how the process works:

  1. You apply the brakes.
  2. The hydraulic pressure makes the piston stick out.
  3. When the piston sticks out, the caliper squeezes the brake pads inwards against the rotor.
  4. The contact between the brake pads and the rotor generates enough friction and heat to stop the rotor from turning.
  5. The rotor is connected to the wheel, so the wheel stops turning too.

This article offers a thorough explanation of brake rotors. It also covers how brake rotors work with the other parts within the braking system.

How To Determine If Your Brake Rotors Are Failing

In normal conditions, brake rotors last between 30K and 70K miles. They can fail much earlier than that, though. When your rotors go bad, you’ll know. Some signs of rotor failure are:

  • Squealing
  • Vibrating
  • Grinding noises
  • Longer stopping distances

OEM Vs. Aftermarket Brake Rotors For Cadillacs

Are you having a hard time deciding between OEM and aftermarket Cadillac rotors? This comparison guide will help you. It covers the three most important features to look for in a brake rotor:

  • Compatibility with the OEM brake pads
  • Size
  • Warranty coverage

The guide concludes that OEM rotors offer much more value than aftermarket rotors because:

  • OEM rotors are 100% compatible with OEM brake pads
  • OEM rotors are always the right size because they’re built to OE specs
  • OEM rotors come with a comprehensive warranty

To Replace Or To Repair

Are you unsure if you should replace or resurface your rotors? This guide will help you. To sum it up:

Resurface your rotors if:

  • Your rotors are still close to new
  • All of your rotors will end up being the same thickness

Otherwise, it’s easier and safer to replace your rotors. It’s actually an easy job you can do at home.
