Characteristics And Service Life Of Brake Pads

To ensure the safe operation of vehicles and driving tools, it is essential to have skilled drivers and reliable brake accessories. Among these accessories, brake pads play a crucial role in potentially saving lives during emergencies. Therefore, it is imperative to select brake pads from trustworthy manufacturers who prioritize quality and honesty. In the following discussion, we will focus on explaining the lifespan of brake pads and its significance in maintaining driving safety.

Brake pads for automobiles are considered consumables and typically require replacement after approximately 50,000 kilometers. Currently, in the market, there are two main types of brake pads available: metal and ceramic.

Even though metal brake pad technology has been around for a long time, it still remains popular for many models that have a heavier weight. This is because the friction coefficient of metal pads can be modified to a wide range. However, a major drawback of metal formula brake pads is that they tend to fall off easily. This is where ceramic brake pads come in.

Ceramic brake pads are known for their noise control and the fact that they don't produce any dust. Developed just after 2000, many Korean and Japanese cars use them since they are light and don't require a high friction coefficient. But like any technology, ceramic brake pads have their share of disadvantages too. For instance, their current friction coefficient is relatively lower than what's achievable with metal pads.

Despite this limitation, ceramic brake pads still have their place in the market. As the temperature increases, their friction coefficient can remain stable, making them an excellent choice for those who value noise reduction and cleanliness. In essence, the choice between metal and ceramic brake pads depends on the user's preference, the driving conditions, and the type of vehicle they're using.

Determining the service life of brake pads is not based on a fixed number of kilometers. This is because the composition of brake pad materials varies, and everyone's driving behaviors and road conditions differ. Consequently, the timing for replacing brake pads can also vary. To determine whether brake pads require replacement, there are a few approaches. Firstly, one can refer to the indicators on the dashboard. If the brake pad indicator light remains illuminated, it is crucial to promptly replace the pads. Additionally, one can also assess the thickness of the brake pads. New brake pads typically have a thickness of around 1.5cm. If the thickness falls below 5mm, it indicates that new brake pads should be considered.

Another method of predicting brake pad wear is through auditory cues. Most brake pads are made of iron, which makes them prone to rust, especially after rain. When the brake pads are rusted, you may hear a hissing sound of friction when you apply the brakes, which is considered normal for a short period. Experienced drivers can even gauge the lifespan of the brake pads and determine if they need to be replaced based on their perceptual effects. By observing the brake's responsiveness and the contrasting braking effect caused by the thickness or thinness of the brake pads, one can gain a firsthand experience of their condition. It is crucial for our driving safety and overall well-being to be cautious when selecting brake pads, remain vigilant, and opt for high-quality ones.
