How Mitsubishi Brake Rotors Work

Here’s a fun fact: the average driver applies the brakes on their car over 200 times a day.

Your brakes are arguably the most important system in your vehicle when it comes to safety. In your Mitsubishi’s braking system, you’d find approximately 40 parts, including calipers, brake pads, and rotors. 

The rotors are the biggest parts in your vehicle’s braking system, and they play a vital role in stopping your car.

What Are Rotors?

Mitsubishi rotors

There is one rotor in each disc brake setup situated behind a wheel. Some cars have two disc brakes (usually at the front wheels with drum brakes at the rear wheels). Other cars have four disc brakes (at all four wheels).

A brake rotor is a metal disc that’s attached to the hub. The same lug nuts and studs that attach the wheel also attach the rotor. Installed over the rotor is a caliper and brake pads. The rotor is the the link between the wheel and the caliper.

How do Rotors Help Stop Your Car?

Every time you hit the brakes, the following process is kicked into motion: 

  1. Hydraulic brake fluid is pushed through the brake lines from the master cylinder to the caliper.
  2. The pressure from the brake fluid makes the caliper squeeze the brake pads inwards against the rotor.
  3. When pressed against the rotor, the brake pads create enough heat and friction to stop or slow down the rotor (depending on how much pressure you apply to the brakes).
  4. When the rotor stops or slows down, the wheel it’s connected to also stops or slows down. This results in the car itself stopping or slowing down.

Do Rotors Wear Out Over Time?

You wear down your brake pads every time you apply the brakes on your Mitsubishi. For this reason, you’re required to replace your brake pads once in a while. Do rotors wear down, too?

Yes, rotors do wear down, but a much slower rate. Rotors can become grooved, pitted, or warped from the continual heat and pressure from the brake pads.

To ensure safety and reliability, regular brake rotor inspections and replacements should be part of your car’s ongoing maintenance. This diagnostic guide is all you need to diagnose bad brake rotors. If you have the right hand tools, it is pretty easy to replace the rotors yourself. You can order genuine OEM replacement rotors from us at a steep discount.
