Brake rotors serve as metal discs attached to a vehicle’s axles. Pushing the brake pedal also results to the brake pads pressing the rotor, further leading to the creation of friction, forcing the wheels to turn slowly.
Such friction, however, also results to a worn out disc that may require resurfacing. Aside from that, there is also a risk that you will need to replace the brake rotors soon because of excessive wear and damage below a certain limit.
The need for replacement can usually be determined based on the number of miles driven, as well as your driving conditions – ex. road salt, rocks, sand, dirt, and heat.
If there is a need for you to replace your brake rotor, then here are five of the best brake rotors 2018 that you ought to consider.
They are considered as the best choices as they have high satisfaction ratings plus the most remarkable features integrated into the product.

Signs that you Need to Replace a Brake Rotor
Brake rotor mainly functions by slowing down your vehicle through the utilization of friction coming from being directly in contact with the brake pads.
Over time, the rotor will wear out, requiring immediate replacement. In this case, you have to watch out for the following symptoms as this indicates the need for replacement:
- Noisy brakes – Expect it to produce squeaking or squealing sounds if the rotor is already severely worn or warped. Severely worn rotors often cause scraping sounds while warped ones produce squeaks.
- Vibrations – These usually come from the brakes. Such is also a sign of excessively worn or warped rotors. You will most likely feel the vibrations on the pedal, and at times, on the chassis.
- Score marks or grooves – You will also know that you need to replace the rotor if you already notice score marks or grooves on it, which usually results from its repeated contact to the brake pads. The problem with both the score marks and grooves is that they can hamper the ability of the rotor to slow down your vehicle. It can also trigger pulsations and vibrations on the pedal.
- Fading – This usually happens when you notice that the brake has become unresponsive. It indicates that there is a leak in the system, requiring the replacement.
- Pulling – This symptom happens when you notice your vehicle pulling to one side each time you apply the brakes. This sign indicates that the brake pads are worn out unevenly, or there is a foreign matter within the brake fluid.
All these signs show that the rotors are already damaged, so it is crucial to give it immediate attention.
Best Brake Rotors - Buyer's Guide
1. Type of your vehicle
Consider this factor along with how you drive it. Most vehicles come with solid vented rotors. Note, however, that there are also high-performance ones, such as Audi, Mercedes-Benz, and BMW, built with cross-drilled or slotted rotors.
You have to keep in mind that each of them requires a different type of rotor, so you have to take this into consideration before making your choice.
Look for a rotor designed in such a way that it has enough thickness that allow it to manage more than two pad replacements. This factor is crucial in your search for the best brake rotors as this determines its ability to provide a more secure breaking.
Also, note that as the rotor wears out and gets a little thinner, it also tends to have less mass, making it incapable of absorbing and dissipating heat. That said, you need to find a rotor with the right amount of thickness – making it last long.
3. Type of brake rotor
Keep in mind that a brake rotor comes in different types, and you have to be aware of their individual differences if you want to pick the right one. One of its types is the smooth rotor, which is capable of delivering a stopping power, which is more than enough for daily driving.
This type also provides an extra surface area, making it highly efficient when it comes to dissipating heat. Another good thing about it is that it is not vulnerable to cracks despite excessive use.
The smooth rotor is ideal if you intend to use it for moderate tracks and pair it with performance brake fluids and pads.
Another type is the slotted rotor, which comes with cut grooves that you can find along the face of the rotor. Heavy braking repeatedly can cause the rotor’s slots to release built-up gasses, which aids in keeping the pads and rotors cooler.
It also has a high coefficient of friction, so expect it to consume less energy. Furthermore, it comes with slotted venting designed to prevent the brake from fading while retaining its stopping power.
Then there is the cross drilled rotor, which works by efficiently venting built-up dust and gas, thereby keeping its cool. Another thing that this certain type of rotor can do is that it lets water escape from the surface, promoting improved initial pad bite, as well as wet-weather performance.
It works well if you intend to use your vehicle on the streets as this prevents your brakes from encountering track-level temperature.
Lastly, there is the slotted and drilled rotor. As the name indicates, it combines the functionality and appearance of the cross-drilled and the slotted types. It is ideal for heavy vehicles that tend to tow weighty loads frequently because of its high level of durability and security.
You have to study the different types of brake rotors as your knowledge about each one can help you determine which one will fit the needs of your vehicle.
4. How you intend to use your vehicle
This is another vital factor in deciding which among the brake rotors in the market is best for you. If for instance, you frequently use your car for commuting, then there is no need for you to go for the race brakes.
Basic and high-quality rotors are often enough for this purpose.However, if it is already loaded with a lot of passengers and gears then installing drilled rotors is a must. If its main use is for towing, drilled or slotted rotors are ideal as these aid in sweeping too much heat.
Other purposes that your vehicle may have are for off-roading, street use and performance, and racing. You need to decide how you intend to use it as this is a huge help in figuring out which type and brand perfectly fit your requirements.
With all these tips and factors considered, plus the short reviews of the best brake rotors today, finding one, which is suitable enough for your needs and your vehicle is easier.
