How to Buy Brake Rotors on eBay

Brake rotors are an integral part of a car’s braking system and they are used to slow down the car or bring it to a complete stop. A brake rotor is a piece of metallic disk placed between the brake pads, and when the brake pads are squeezed, they clamp down on this rotor to stop the spinning wheels. Due to this important role of brake rotors, they have to be checked from time to time to ensure that they are in good working condition and should be replaced as needed. When replacing brake rotors, users should know what kind of rotor is right for their car. Brake rotors come in many materials and designs to match the specifications of different cars, so users should understand these differences before heading out to buy them. Once they have a clear idea of the material and design they need, they can buy the brake rotor of their choice on eBay Motors.

Kinds of Brake Rotors

There are two broad kinds of brake rotors and they are drilled rotors and slotted rotors. Each type has its own design and consequently has certain advantages and disadvantages associated with it. Both the drilled and slotted rotors are explained below to give users a good idea of what they are. When users have made their choice of brake rotors, they can visit eBay Motors to buy them, as a wide selection of both these kinds of brake rotors is available here.

Drilled Brake Rotors

Drilled brake rotors, as the name implies, have holes drilled into these metallic plates. Though a lot of people tend to think that this is counter-productive and reduces the efficiency of the braking system, it is not true. In fact, they are more efficient and longest lasting because these holes dissipate the heat that is generated due to friction when the brake pads squeeze each other, thereby prolonging the life of the brake pads.

Drilled brake rotors are also the right choice if users tend to drive a lot during rainy weather or through large puddles of water. This is because the water from the outside can easily enter the braking system and this can make the rotors slippery, making it difficult for the brake pads to hold. Therefore, when users use drilled rotors, the water will drain out of the braking system easily and the brake pads will be more efficient. The biggest disadvantage of drilled rotors is that repeated drilling makes the brake disk weak, so it can crack easily and may need to be replaced frequently.

Slotted Brake Rotors

Slotted brake rotors have slots attached to the rotors to push away the heat generated due to friction when the brakes pads squeeze the rotors. These slots also push out the water that enters the braking system while driving in rainy conditions. Another advantage with these rotors is that they are not weakened by any drilling as the slots are attached to it on the outside. This makes it the right choice for performance vehicles such as race cars because these brake rotors will not break down that easily.

The downside of slotted brake rotors is that they tend to wear down the brake pads quickly and this is why drilled brake rotors are the preferred choice for regular driving.

Motorcycle Brake Rotors

Motorcycle brakes are similar to car brakes, except that there are two sets of brakes on motorcycles. Each of these two brakes operates independent of each other unlike in a car where all brakes work together to stop the vehicle. Therefore, brake rotors are all the more important for motorcycles and two sets are needed for every vehicle.

Drilled brake rotors are the most common type used for motorcycles, though the performance models are often fitted with slotted rotors. Additionally, brake rotors are visible on the outside in motorcycles, so their design is customized to match the overall design of the bike. In fact, many motorcycle manufacturers shape or drill their rotors for better looks.

Truck Brake Rotors

Trucks are much larger and heavier than cars, so a more powerful braking system is needed to stop these vehicles. To meet the needs of these heavy-duty vehicles, they are fitted with larger rotors. In addition, truck brake rotors are made of more durable materials, such as cast iron or steel. Despite their durability, truck rotors have to be changed frequently because of the added stress on the brake pads.

Mountain Bike Brake Rotors

Mountain bikes are fitted with cross-drilled brake rotors because they distribute the heat better when brakes are applied suddenly. Additionally, downhill bikers tend to apply brakes more frequently, so these brake rotors are more durable and last longer.

Brake Rotor Materials

Brake rotors are made of different materials to suit different vehicles. Some of the common materials used for making brake rotors are cast iron, steel, layered steel, aluminum, carbon, and ceramic. Each of these different materials is explained below to give users a good idea of what material to choose. One of the best places to buy brake rotors of any material is eBay Motors because of its wide selection and reasonable prices.

Cast Iron Brake Rotors

Cast iron brake rotors provide the best performance and are particularly suited for heavy-duty vehicles like trucks. Most of these rotors have a hat-like shape that consists of a cast-iron ring and a piece of circular aluminum that are joined at the ends. Many standard cars do not use these cast iron brake rotors because there is no space for the rotors to expand when heat is applied, which means they break frequently and need to be replaced often.

Steel Brake Rotors

Steel brake rotors are lightweight and they have the capacity to take an additional amount of heat. However, they are a lot less durable when compared to other brake rotor types and this is why they are not a popular choice among users.

Layered Steel Brake Rotors

Layered steel brake rotors, as the name implies, is made of layers of steel to give more durability for the brake rotor. However, they are not widely produced, so they are rarely used.

Aluminum Brake Rotors

Aluminum brake rotors are also not the first choice for users because they tend to absorb heat quickly. Aluminum is not hardy and can melt quickly, so this is another reason for its limited use in brake rotors.

Carbon Brake Rotors

Carbon brake rotors are made of carbon and iron to increase their capacity to absorb heat and to distribute it evenly. Additionally, the addition of materials such as silicon reduce noise and vibration and can withstand a higher amount of stress. For these reasons, they are popularly used among high performance vehicles.

Ceramic Brake Rotors

Ceramic materials can retain more than 80 percent of heat, which makes it a good choice for cars that have high stress levels, such as race cars. In addition, they are lightweight and have a higher performance rate.

Buying Brake Rotors on eBay

If you are looking to buy the best brake rotors without spending a ton of money, then eBay Motors is the place for you. The site has a staggering variety of brake rotors, so you are sure to find the brake rotor you want. When you know the brand name and model, you can type it in the search box and this will bring up all the listings relate to your brand and model name. On the other hand, if you do not know the exact model, but you want a particular kind of brake rotor, then you can type in the related words. For example, if you are looking for ceramic brake rotors, then you should type in the words “ceramic brake rotors” and this will bring up all the ceramic brake rotor listings available on eBay Motors.

Top-rated Sellers

When you can choose to buy from the Top-rated Sellers on eBay, you are sure to get great customer service and prompt delivery. These sellers have consistently received good ratings from past buyers and they have an excellent track record of selling on eBay. To identify these top-rated sellers, look for the top-rated sellers batch right next to their user ID.


The brake rotor is the disk placed between two brake pads and it is an integral part of an automobile’s braking system. When the user applies the brake, the brake pads hold on to the rotors to stop the spinning wheels, and this is why a good quality rotor is essential for the vehicle’s safety. Depending on the size and type of vehicle, users can choose from the many brake rotors available on the market today. There are two broad kinds of brake rotors and they are the drilled and slotted rotor. Each kind has its own advantages and disadvantages and it is up to the user to decide which one is right for his or her vehicle. Irrespective of their choice, users can find the best brake rotors at low rates on eBay Motors.
