  2. Why are the brake pads noisy?

Noise is a common problem that occurs during the braking process. This issue can be attributed to frequency resonance, which happens when the natural frequencies of two components or materials match. If left unaddressed, it can cause damage to the brake assembly system and reduce the lifespan of the brake disc. However, this problem can be easily solved by choosing the right type of brake disc that does not produce too much noise. In many cases, people mistakenly assume that brake pads are causing the noise, but the reality is that the entire brake assembly system contributes to this issue. Therefore, it is important to understand the root cause of the problem to find the right solution. By doing so, we can ensure a smooth and safe braking experience.

My hypothesis is that an increase in the amount of metal content would result in the material becoming extremely tough. However, with that level of toughness, a high level of noise would be produced. To summarize, greater metal content equals greater hardness, but also an increase in noise level.

It is important to be wary of the false claims made by some auto repair shops regarding brake pads and their composition. Contrary to popular belief, noise levels are not directly linked to the hardness or softness of the brake pad. The initial American cars contained a high amount of metal and were mainly semi-metallic. However, the metal in brake pads is primarily used to connect fillers and conduct heat, and its hardness is similar to that of the valve disc, which does not cause significant wear to the disc. The metal grindings visible on the brake disc are not what ultimately improves braking ability, but rather ground fillers that are harder than the disc itself. These fillers are typically made of emery, similar to the sandpaper and grinding wheels found in workshops. Therefore, it is essential to be aware of the composition of brake pads and rely on scientific evidence rather than unverified claims.

Some plates have grooves for better braking performance. Yes, brake pads are made of hard material.

The hardness of brake pads is regulated by a national standard, with the acceptable range typically falling between 35 and 70 Shore hardness. It's important to note that this hardness level does not significantly contribute to brake disc wear. Rather, the wear additive used in the brake pad is the main component that affects wear. Surprisingly, whether a brake pad is hard or soft isn't the leading cause of brake disc wear - it all boils down to the quality of the wear-resistant additives used. In many cases, low-cost materials are to blame.

The short service life of brake pads is a significant problem. Additionally, inferior brake products have a long braking distance during emergency situations. It is crucial to understand the reasons behind these issues.

The main issue with the short service life of brake pads is the quality of the materials used in their construction. When inferior materials are used, the brake pads wear out quickly, leading to reduced performance and a shorter lifespan. This can be dangerous as it increases the risk of brake failure, compromising the safety of the vehicle and its occupants.

Furthermore, inferior brake products often have a long braking distance during emergency braking. This is primarily due to the poor design and manufacturing processes employed in their production. Brake systems need to provide sufficient stopping power in emergency situations to prevent accidents. However, inferior products fail to meet these standards, leading to longer stopping distances and potentially devastating consequences.

To tackle these problems, it is important to invest in high-quality brake pads that are manufactured using superior materials. This can significantly improve their service life and ensure optimal performance during emergency braking scenarios. Additionally, conducting thorough research and selecting reputable brands can help avoid purchasing inferior brake products. Ultimately, prioritizing safety and investing in reliable brake components is crucial for maintaining vehicle performance and protecting lives on the road.

The strength of the intermolecular connection within a material decreases significantly at high temperatures, as with any object. When it comes to braking, the concept is to convert kinetic energy into heat energy through friction, ultimately achieving the desired braking effect. As a result, a substantial amount of heat is generated from the friction between the brake pad and the brake disc, causing it to accumulate on the surface of the brake pad's friction material. To ensure the brake pads can withstand such high temperatures and maintain their strength, specific materials must be chosen. These materials, such as high-temperature resistant resin, high-purity graphite, and high-purity barium sulfate, are comparable to hand-picking only the best pieces of coal from a carbon car, which unfortunately leads to an increase in cost.

On the contrary, low-quality brake pads do not utilize such high-quality materials, therefore, they cannot guarantee stability under high-temperature conditions. As the speed of the vehicle increases, so does the heat, temperature, and as a result, the strength of the connection weakens. This, in turn, reduces the braking capability and extends the braking distance. Thus, a brake pad that performs well during city driving at speeds ranging from 20 to 60 km/h does not necessarily offer the same stable braking performance at higher speeds.

Furthermore, when the molecular chain's connection strength weakens due to elevated temperatures, the wear and tear accelerate in response. This is one of the reasons why brake pads from general brands have a relatively short service life, especially in mountainous areas or under frequent emergency braking situations.
