The braking system in your Porsche is without a doubt the single most important mechanism. The system can easily be the difference between life and death. Think about it this way. Without brakes, your car will have to rely on time to slow down its forward momentum.
But how do brake pads work in the first place? It is easy. Each time you step on the brake pedal, the car pushes fluid through brake lines into all wheels. This simultaneously brings the tires to a stop. As a while, the braking system turns your Porsche’s kinetic energy into friction which halts motion. The brake pads are the source of friction. They come in four different varieties which include:
Asbestos Brake Pads
Brake pads were originally made of asbestos. The material is heat absorbing and well suited for the frequent wear and tear factor that brake pads take. Unfortunately, asbestos was found to be life-threatening as it is a highly potent carcinogen. In short, asbestos was a good material for brake pads but a bad compound health wise. An alternative had to be found.
Organic Brake Pads
Organic Porsche brake pads are a mixture of materials like carbon, rubber, Kevlar, glass and fiberglass bound together with resin. They produce less glass than metallic brake pads. That is not all though. Organic brake pads are affordable and generate moderate friction. This means they do not produce too much heat, which is a plus because they do not shorten the lifespan of rotors.
Despite all the perks that come along with organic brake pads, they also feature a few cons. Their composite nature means they hardly last for long. You will have to replace them more often. They also cannot withstand extreme temperatures.
Ceramic Brake Pads
They are made of the same ceramic material used to make ceramic plates and pottery. The only difference is the fact that the ceramic used to make brake pads is denser and more durable. Unlike organic brake pads, ceramic brake pads feature fine copper fibers embedded within them. This increases conductivity and friction. They guarantee low noise levels, produce less dust and can withstand harsh driving conditions as well as heat.
There are downsides, which hardly have anything to with their design or material. Cost is one such downside. They are more expensive compared to other brake pad materials. They are also not ideal for racing conditions or cold climates.
Metallic Brake Pads
The metallic brake pad or the semi metallic brake pad is yet another option you have when it comes to choosing brake pads. They are made of 30% to 70% metal which includes copper, iron, steel or other composite alloys. The metals are combined with graphite lubricant and other fillers to complete the brake pad. They can withstand extreme heat and the same time help braking systems cool down. They also do not need one to exert too much pressure on them.
More noise and compared to organic and ceramic brake pads are some of the cons that come along with metallic brake pads. They can also add more strain on rotors. Dust is yet another downside as they produce more debris and brake dust than the aforementioned brake pad types.
Choosing The Best Option
Your choice should be informed by things such as your budget and your driving habits. An urban commuter would do well with ceramic brake pads. His or her counterpart with a high performance Porsche sports car would do well with semi-metallic Porsche brake pads.
