The purpose of your Nissan’s braking system is to slow down or stop the vehicle as quickly and smoothly as possible. The braking system contains several parts, including calipers, brake pads, and a master cylinder.
In a disc brake setup, there is a rotor behind each wheel. If you came here looking to learn more about brake rotors, today is your lucky day. This guide has all the information you need to know about the rotors on your car.
What is a Brake Rotor?
When you remove the lug nuts on your wheel and then take the wheel off, you’ll see a metal disc that’s about 12” in diameter. That’s the rotor, and it’s one of the parts in your Nissan’s disc brake system.
Some cars have disc brakes on all four wheels. These cars have four rotors – one at each wheel. Other cars have only two disc brakes, usually on the front wheels (and drum brakes on the rear wheels). These cars have two rotors – one at each wheel.
The rotor is connected to three major parts:
- The hub
- The wheel
- The brake system (via the caliper and brake pads)
A rotor may be just a metal disc, but it plays a huge role in the operation of your brake system. In fact, the disc braking system is named for the rotors.
How the Rotors Assist in Stopping Your Car
The rotor rotates along with the wheel. When you hit the brakes, the caliper squeezes the brake pads against the rotor. The contact between the brake pads and the rotors creates enough heat and friction to either slow down the rotor or stop it from moving. Because the wheel is attached to the rotor, it also slows down or stops rotating.
When to Replace Your Rotors

It’s common for a rotor to wear out enough to stop working properly. When this happens, all sorts of braking performance problems will arise. It’s because a bad rotor reduces the braking power of the vehicle. Some of the issues you’ll experience include:
- Increased stopping distance
- Increased noise and vibration when stopping
- Increased brake fade
If you find that one of your rotors has gone bad, it’s a good idea to replace it right away. For optimal stopping performance, it’s recommended to replace your rotors in pairs. Luckily, rotors don’t have to be expensive. At NissanPartsPlus.com, we offer genuine OEM Nissan rotors at wholesale prices.
