Every driver must ensure the full safety of their vehicles to prevent road accidents. The best brake rotors (being the essential part of any brake system) are meant to make every vehicle safe enough, as they guarantee that the brakes will stop your vehicle when necessary.
As this is a disposable car component, a brake rotor should be replaced soon after it starts losing its technical properties. It should be mentioned that there are two main types of brake rotors that are currently installed in modern cars. These are front brake rotors and rear brake discs. The main difference between them lies in the fact that the front brake rotors are a lot heavier than the rear brake discs due to the fact that they need to handle more heat (when your car is braking, the center of its gravity pushes forward, so the front wheels become affected more). Rear brake rotors are often set up for the braking brake. In most cars, the front brake rotors take from 60% to 75% of the braking power, while the rear ones are responsible for the remaining 25-40%. Even if you realize the necessity of having only the best rotors installed in your car, it can be still challenging to find a suitable model for your vehicle.
I have chosen top ten brake rotors (5 front brake discs and 5 rare brake discs) that you can find on the market today. After reading the article, you will find the best option to be installed in the car. I find it also important to mention that you can find even truck rotors here. Moreover, this article will also teach you how to replace the warped brake rotors with the new ones and how to check the brake rotor thickness to ensure the adequate maintenance of the brake system.

This brand is best known for producing high-quality automotive products, which are made by ISO certified factories to deliver perfect fit, shape, and function. This particular brake disc boasts a precise hub hole chamfer that offers a hub centric fit.
I believe that the greatest upside of the BR900526 lies in its multiple vane configuration features, which is meant to ensure free airflow (by forcing out hot air and pulling in cool air) and guarantee adequate heat dissipation and vibration-free braking. Another positive feature intrinsic to these rear brake rotors is their non-directional swirl finish that will guarantee an easy-going installation without preliminary machining of the brake disc.
The model goes in standard and EP-coated versions, so you can pay some extra dollars to opt for an EP-coated brake rotor that is meant to have even better anti-corrosion properties. Pay attention to the fact that the item is sold as a single unit, so you should buy two brake rotors to have them installed in your car. I also want to mention that this model weighs as much as 12.12 pounds and has medium dimensions (12.5 x 12.5 x 2 inches). The most disappointing thing is that this is the aftermarket option only.
- Customer-friendly price.
- It can be installed in different vehicle types ranging from small cars to SUVs.
- The item tends to make some noise when your car turns and weight shifts, especially if you own an SUV.
This rear brake disc promises to be a lasting option as it is made out of heavy-duty materials and features an E-Shield coating that should ensure perfect anti-corrosion protection.

Best Front Brake Rotors
ACDelco 18A1705 — best brake rotors for trucks
These shining brake discs have proved their exceptional quality during tests. As the test has revealed, the item is very good at noise reduction and smooth brake operation. I think that this partially comes from the fact that the 18A1705 has been inspected for balance before going to the market.
My experience says that the ACDelco brake rotors are made according to the original designs of OEM manufacturers in order to be used as perfect OEM replacement options. It seems to me that this model is good at dispersing heat as its design is intended to guarantee adequate airflow. Moreover, these brake rotors are made in the USA and feature a thickness variation technology (is less than 0.0004), which is meant to ensure flawless noise reduction and prolong a brake pad life through minimized pedal pulsation. Despite the fact that the model has a non-coated exterior, it can be easily installed in your car right out of the box without preliminary machining.
The only thing I do not like in this model is that it is extremely heavy weighing sensational 26 pounds, although it has average dimensions as for brake rotors (13.3 x 13.3 x 2.9 inches). This derives from the fact that this is a product made out of heavy-duty materials called to increase its lifespan. Again, by two items to ensure perfect performance.
- This model can be easily removed and installed.
- You can use it on most vehicle types up to vans.
- The item’s expensive price will hit your wallet.
It is worth mentioning the Detroit Axle S-54153 in our brake rotor review. It is a pair of cross-drilled and slotted brake discs that should be installed on both driver and passenger side. The product’s well-engineered design guarantees that this front brake rotor will have adequate airflow and ideal heat dissipation. At the same time, the item seems to work well enough at lower temperatures too. The manufacturers have created the product precisely to empower it with vibration-free performance. I also think that the choice of a high-quality carbon-fiber ceramic compound as the core material in this model is what gives this product brilliant braking performance, especially when compared to traditional ceramic brake pads.

What is a Brake Rotor?
A brake rotor is an essential part of the car brake system, which ensures a safe and smooth ride. Obviously, you should never use a car that has problems with its brake system, as it may result in an accident. As it can be understood from its name, a brake rotor is a braking disc that has a function of stopping your vehicle when necessary. Basically, brake discs are what your car’s brake pads clamp down on to block the wheels and stop their spinning movement. When your wheels get blocked, your car will have no choice but to stop.
By installing reliable front and rear brake rotors, you make your vehicle safer. Remember that having a good-working brake system is a must for all drivers, as even several inches can save a life during a crash. A brake rotor is exactly a car component that ensures that your vehicle will stop as fast as possible after you have pushed on the brake pedal.
When to Replace Brake Rotors?
A key to keeping your brake system in perfect conditions is to replace warped brake rotors in a good time. Depending on the quality of materials, your driving style, and other related issues, your brake discs should be replaced after 15,000 to 70,000 miles. There are six core problems that usually persuade drivers to replace their brake rotors. These are warping (brake discs lose their initial braking ability over time), dishing (when brake rotors lose their initial shape and get thinner), hot spots and bluing (as they are constantly affected by heat), rust (as their anti-corrosion protection gets weaker), deep grooves (brake discs can no longer provide effective braking performance), cracks (when a problem with your brake discs becomes visible).
How to Remove Brake Rotor?
In fact, there is nothing difficult at replacing brake rotors yourself, as most brands are trying to guarantee an easy-going installation and removal of their brake discs. These are the main steps you should perform in order to install a new a pair of brake rotors in your car:
- The first step will be to slightly loosen the wheel lug nuts, jack up your car, and secure with wheel stops and jack stands.
- Push the brake pedal approximately 15-20 times to release the residual pressure. Then unscrew the lug nuts and remove the wheel.
- Then unbolt two brake caliper fasteners that can be found on the rear of the caliper. You should better unbolt the bottom fastener before removing the upper one if you want to make things easier. You can use some lubricants if rust is a problem in your case.
- Now you should unbolt the caliper from two bracket bolts located on the steering knuckle. Again, you can use lubricants to cope with rust.
- Take off the caliper from the disc and hang it from the vehicle. Do not hang it over the brake line in order to prevent it from getting damaged.
- Then remove the brake disc from the wheel studs. You can use a hammer if things go slowly. Do not forget to put an anti-seize lubricant on the axle hub between the wheel studs.
- Now compress the caliper piston to make the caliper sliding back on the rotor.
- Put some removable thread locker on the steering knuckle bolts.
- Clean the caliper guide pins and then add some lubricant before sliding them in.
- Add brake fluid and press the brake pedal to check that everything works fine.
- Put the wheel back properly and check the brakes again. If they work well, you can hit the road again!
How to Measure Brake Rotor Thickness?
It is vital to inspect the rotors for defects in order to be sure that the vehicle’s brake system functions well. You can do this whenever the brake pads or calipers are removed. If you need to measure brake disc thickness, you should do the following procedures:
- Take a micrometer to measure the brake rotor thickness of 0.40 inches (10mm) inside the outer circumference of the brake disc every 45°.
- Look at the smallest value measured and compare it to the minimum thickness specifications indicated on the brake rotor. If you see that the rotor thickness is below the minimum required point, you should immediately replace your brake disc.
