How to See if Your Subaru's Rotors Need to be Replaced Yet

Ever wonder if it's time to replace the rotors on your Subaru? The condition of the rotors is essential in maintaining the vehicle's stopping power. However, at some point, your rotors will start wearing out and begin to lose their ability to stop your car. Also, sometimes the rotors will get damaged from repeated metal-to-metal contact with worn brake pads (or simply from being paired with the wrong type of brake pads).

This guide will list the symptoms of a bad rotor and then show you how to inspect your rotors.

Warning Signs That You Have a Bad Rotor

Worn rotor

There are a few signs that tell you that you need to check out your rotors soon, and they are:

  • A pulsation in the brake pedal or steering wheel
  • A clattering noise coming from the brakes
  • A squealing or squeaking noise coming from the brakes
  • Increased stopping distances

If you experience any of these symptoms, then it's worth taking the time to visually inspect your rotors to see if they're indeed worn or damaged.

Removing the Wheels

To reach your brake rotors for a visual inspection, you have to remove the wheels on your car. Here's how you can do this safely and efficiently:

  1. Loosen the lug nuts on all of the wheels you're going to remove by about 1/4 of a turn.
  2. With a floor jack, lift one end of your Subaru just enough to take all the weight off the wheels. It's a good idea to put a 2x4 between the floor jack and the frame for added protection.
  3. Undo all of the lug nuts on the wheels and then remove the wheels. Now, you can see the rotor behind the wheel.

What to Look For While Inspecting the Rotors

When you have the rotor in front of you, look for the following signs of excessive wear or damage.

  • Deep grooves or scoring
  • Blueish burn marks from the brake pads
  • Noticeable lip along the outside edge of the rotor (in this case, measure the rotor thickness to see if it still meets the minimum thickness requirements, which should be stamped on the outer edge of the rotor)
  • Cracks
  • Variation in the rotor thickness

So You Have Bad Rotors. Now What?
