Ceramic Brake Pads
Ceramic brake pads offer great braking performance, wear well over time and are very lightweight -- all of which are important for high-performance driving. So again, what's the problem with ceramic brake pads? They're very expensive.
Ceramic brake pads may be expensive, but they can withstand the extreme heat generated by high-performance race cars.
Ceramic brake pads are made from ceramic fibers, filler material, bonding agents and they may even have small amounts of copper fibers within them as well. Because they're mostly ceramic, these brake parts dissipate heat well, which keeps performance strong, even after repeated hard stops. They also don't break down very much with repeated use; that means they produce less dust than other types of brake pads -- and the dust that they do produce is lighter in color and doesn't stick to the wheels. However, because they're so expensive, ceramic brake pads aren't for every type of vehicle.
Sports cars that are routinely driven hard -- as part of club racing, for example -- can benefit from ceramic brake pads; however, almost every other vehicle performs just fine with other brake pad materials. For most drivers, the extra performance of ceramic brake pads isn't worth the extra cost.

Metallic Brake Pads
Most vehicles on the road today have metallic brake pads. In case you're wondering, these brake pads aren't just slabs of metal. They're typically made of iron, copper, steel and graphite all mixed and together and bonded to form the pad material.
Metallic brake pads are perhaps the most common brake pads found on cars today. The brake pad on the left is new; the pad on the right is used.
The reason that these pads are so common is simple -- metallic brake pads are cost-effective and durable. They provide good performance and are good at transferring the heat generated by friction with the brake rotors. The downside of metallic brake pads is that they're heavy, which can have a (small) negative impact on the car's fuel economy. Also, because of the extra weight, metallic brake pads aren't the best choice for high-performance driving. Being made of metal makes the pads very hard. That's what makes them durable. But because there isn't as much "give" in metallic brake pads, they can cause more wear on the brake rotors than other types of brake pads. The metallic brake pads themselves hold up well, but they often negatively impact the durability of other brake parts. Finally, metallic brake pads work best when they're warm. When a vehicle with metallic brake pads first gets going on a very cold day, stops may take slightly longer than usual until the brake pads heat up.
For most drivers, the positives of metallic brake pads outweigh the negatives, especially since metallic brake pads are good for stopping heavy vehicles like trucks.
Motorcycle Brake Pads
Motorcycles frequently use either ceramic or organic brake pad material.
Motorcycle brakes work on the same principle as automotive brakes: The transfer of an action from the driver into a force that stops the wheels. When the driver of car or truck applies the brakes all four wheels work together to slow or stop the vehicle. On a motorcycle, the front and rear brakes usually operate independently of each other. Most motorcycles have independent, hand-operated for controls each brake. The front brake tends to be more effective, delivering the majority of the stopping power. Because of this, motorcycle brake pads are a key component of motorcycle safety and an important brake part.
Motorcycle brake pads are manufactured using the same materials used in automotive brake pads; however, ceramic and organic brake pads are the most common. Because motorcycles are smaller and weigh considerably less than cars and trucks, organic brakes pads don't wear as quickly as they would on a car.
Up next, we'll find out how the big trucks slow their heavy loads to a stop.
Truck Brake Pads
Because trucks are so big and heavy, their brake pads are especially important. It takes a lot of power to stop a fully loaded truck moving along at highway speeds. Heck, it even takes a lot of power to stop an empty truck that's barely moving at all. That means that the strength of the pad and its ability to stop heavy loads repeatedly is very important. Organic brake pads, because they are soft and wear more quickly than other types of brake pads, are not recommended for trucks. So what type of brake part do you suppose is appropriate for a large truck?
Large trucks often use ceramic or metallic brake pads -- both are known for strength and durability.
Metallic and ceramic truck brake pads are good choices. Ceramic brake pads offer a lot of stopping power, even for heavy loads, but remember, they're very expensive. Metallic brake pads are less expensive; however, they wear the rotors much faster than the ceramic pads. The type of truck and what it's used for should determine the brake parts that are installed on it.
Obviously, a compact truck that's used mainly for commuting to and from work won't need the high-performance brake pads that a heavy-duty truck that routinely tows heavy loads through the mountains will require. Again, the type of truck brake pad material selected really depends on the size of the truck, the weight of the load that it will be hauling and the terrain to which it will be subjected.
Performance Brake Pads
You may think acceleration is the most critical factor for high performance cars, but most professional drivers will tell you that the brakes are equally important. After all, you can't win a race if you go crashing through a wall. Remember, in all cars (but performance cars especially), brakes aren't just about stopping. They also aid the car's handling through turns. So even though performance cars may look like they're going all-out during a race, the brakes are also getting a pretty good workout, too. High performance brake pads and other brake parts have to be able to keep up.
A professional race car driver counts on the vehicle's brakes functioning properly -- in fact, their life depends on it.
One of the most important components of high-performance brake pads is their ability to dissipate heat. If the brake pads get too hot, the brakes will fade -- often boiling the hydraulic brake fluid in the process. Brake fade occurs when braking components get too hot, resulting in a loss of stopping power.
Because brake fade is such a concern in racing, most high-performance brakes are ceramic; however, some very high-end race cars are beginning to use materials like carbon fiber. Both ceramic and carbon fiber brake pads are lightweight (another concern for performance drivers) and dissipate heat well so they stay strong throughout the race. The major downside is their expense. As we've already mentioned, ceramic (and carbon fiber) brake pads are very expensive.
