Brake Rotor Buyer's Guide For Mazdas

Unlike some car parts, brake rotors require regular attention and maintenance. So as a Mazda owner, you might want to know a thing or two about rotors. This buyer's guide covers pretty much everything there is to know about rotors, from how rotors work to how to replace them on your Mazda.

1. How do Brake Rotors Work?

Rotors are mounted to the wheel hub. A caliper wraps around about a quarter of the rotor. Within the caliper are brake pads - one on each side of the rotor. Here's what happens when you hit the brakes:

  1. The brake fluid from the master cylinder creates hydraulic pressure in the caliper.
  2. The pressure in the caliper makes the piston(s) squeeze inwards.
  3. When the piston squeezes inwards, the brake pads are pressed against the rotor.
  4. The friction between the brake pads and the rotor brings the rotor to a standstill in a matter of seconds.

This article walks you through the process in more detail.

2. How do I Know if One of My Rotors is Bad?

Rotors have to be replaced every now and then. It’s common for rotors to wear out after 50,000 miles. Sometimes a rotor will warp or wear out before it hits 50,000 miles due to incompatibility with the brake pads or something else. It's always good to know the symptoms of a bad rotor so you can check out your rotors and replace them if needed. This article has a list of symptoms of a bad rotor, as well as detailed instructions on inspecting your rotors.

3. Should I Buy OEM or Aftermarket Replacement Rotors?

When it's time to replace your rotors, you have to decide between OEM rotors and aftermarket rotors. It's a pretty big decision because there's a huge difference between the two types of rotors in terms of quality and design. This comparison guide will help you weigh the options by discussing the three most important factors to consider: specs, materials, and warranty.

4. How do I Replace the Rotors on my Mazda?

If you have bad rotors on your Mazda, you don't have to bring your car to the shop to have them replaced. You can certainly replace the rotors at home with basic hand tools and the set of step-by-step instructions we put together the other day. Basically, you have to remove the wheel and move the caliper out of the way before switching the rotors.
