In this article, we will discuss the difference between the friction pads of front and rear bicycle brakes and their applications from the perspective of friction pads.
* Working principle of friction pads
When the rider pulls the brake handle, the brake cable will be tightened, and through the mechanical transmission device, the brake mounted on the frame will press against the wheel rims or discs, generating friction, thus realizing the purpose of decelerating or stopping the bike. The core of this process is the friction pads. Friction pads of different materials and configurations can make a big difference in braking effectiveness.
* Friction plate material classification
1. Metal matrix composite material: This type of material is mostly used in mountain bikes and other models that require high strength. It is characterized by good high temperature resistance and strong wear resistance, but the noise is larger.
2. Resin-based composite materials: often used in urban leisure models. The advantage is smooth braking, low noise; the disadvantage is that it is easy to soften at high temperature, resulting in performance degradation.
3. Ceramic-based composite materials: this material combines the advantages of the above two materials, both good resistance to thermal degradation ability also has a small noise output. However, the cost is higher, commonly used in high-end products.
* Difference between front and rear wheel brakes and applications
Front Wheel Brake
--Features:Front wheel brakes provide most of the braking force (about 70%), especially in emergencies, front brakes can reduce speed faster and more effectively.
--Friction plate selection: Considering that front brakes are subjected to greater loads, friction plates made of metal matrix composite materials are usually selected to improve durability and stability.
Rear Brake
--Features:The rear brake is made of metal matrix composite material.
--Characteristics: Compared with the front wheel, it plays a supplementary role (about 30% of the total braking force). It is mainly responsible for controlling the balance of the bike's stance and preventing slippage.
--Friction plate selection: In view of its mild and infrequent action characteristics, resin-based composite materials can be used to minimize noise and maintain lightness.
* Conclusion
To summarize, it is very important to choose the right friction plate material according to the specific needs. For professionals who are looking for the ultimate performance experience, metal matrix composite materials emphasizing wear resistance and stability are the best choice; while those who pay more attention to quietness and comfort in their daily travels can choose resin matrix composite products. At the same time, the combination of different types of friction pads under specific conditions can also achieve the desired effect. The rational combination and use of various types of friction pads can not only make the riding process become more safe and reliable, but also significantly enhance the overall driving pleasure!
