Is the higher the coefficient of friction of the brake pads, the better?
As we all know, the brake pads convert the kinetic energy of the vehicle into heat energy through friction, so as to achieve the purpose of braking. The coefficient of friction, as an important factor that directly affects the friction force, naturally attracts everyone's attention and is regarded as an important performance index.
In layman's terms, the coefficient of friction of brake pads is a numerical value representing the magnitude of friction under the same pressure conditions. The larger the coefficient of friction, the greater the friction under the same pressure, and the easier it is to brake the car.
That being the case, is it true that the larger the friction coefficient of our brake pads, the better?
not really. Of course, the coefficient of friction cannot be lower than a certain level—a too low coefficient of friction makes the braking distance longer under the same pedal force, which is likely to cause accidents; but it cannot be understood one-sidedly that the higher the coefficient of friction, the better. Instead, it must conform to the actual situation of the vehicle and the national standard. Generally, depending on the inertia of the vehicle, the friction coefficient is also somewhat different.
High friction coefficient of brake pads does not mean high safety factor
Although a higher coefficient of friction can often provide stronger braking force, it can sometimes have a counterproductive effect, especially when the car brakes suddenly at high speeds. If the coefficient of friction is too high, it may cause the wheels to lock up, causing the vehicle to spin. Tail, skidding, causing safety accidents.
High friction coefficient of brake pads does not mean good braking performance
The most important thing about the braking performance of brake pads is not how high the friction coefficient marked on the brake pad is, but how high its friction coefficient can be under various extreme road conditions such as high speed, high temperature, water, winding mountain roads, and continuous sudden braking. No remains stable. Some inferior products can achieve a high friction coefficient by adding abrasive materials, but the braking force declines rapidly in the above emergency situations, and even loses the braking ability.
Excessive coefficient of friction affects other performance
The most basic core function of brake pads is to brake the car, but in addition, our performance requirements for noise, dust, wear and other aspects during the braking process are also gradually increasing. Generally speaking, if the friction coefficient of the brake pad is too high, it will increase the dual wear of the brake disc, causing damage to the disc and dust, and it is often more prone to abnormal braking noise. At the same time, an overly sensitive foot feel will also increase the frustration when braking and affect comfort.
In short, the friction coefficient of brake pads is based on the actual conditions of different vehicles, comprehensive technical indicators such as driving speed, torque, inertia, braking distance and comfort, and the results of multiple verifications such as theory, experiments and actual vehicle tests.
