In modern logistics and transportation, trucks, as efficient and large-capacity transportation tools, undertake the important task of global cargo flow. Truck brake pads, as the core components of the braking system, directly affect the safety and reliability of the vehicle. With the continuous improvement of safety standards in the transportation industry, it is particularly important to understand the performance, maintenance and purchase points of truck brake pads.
Working principle and importance of brake pads
Truck brake pads generate braking force by friction with brake discs or brake drums to slow down or stop the vehicle. Since trucks usually carry heavy objects and have long mileage, brake pads need to withstand extremely high temperatures and pressures. High-quality brake pads should have high temperature resistance, wear resistance, low noise and stable braking performance to ensure rapid response in emergency situations and avoid accidents.
Material and classification of brake pads
Common truck brake pads on the market are mainly divided into the following categories:
Asbestos brake pads: Widely used in the early days, but because asbestos is harmful to the human body, it has been banned in most countries.
Semi-metallic brake pads: Made of a mixture of metal fibers and friction materials, they are resistant to high temperatures and wear, but may produce higher noise.
Ceramic brake pads: Made of ceramic fibers and special composite materials, they have the characteristics of low noise, low dust and long life, and are suitable for long-distance transportation.
NAO (non-asbestos organic matter) brake pads: environmentally friendly materials, smooth braking, but slightly inferior to semi-metallic and ceramic brake pads in wear resistance.
Maintenance and replacement of brake pads
The degree of wear of truck brake pads directly affects the braking effect. The driver should regularly check the thickness of the brake pads. If the wear exceeds the limit (usually less than 3 mm), it needs to be replaced in time. In addition, other parts of the brake system, such as brake discs, brake oil pipes, etc., should also be checked simultaneously to ensure the overall stable braking performance.
Purchase suggestions
When purchasing truck brake pads, products that meet international safety standards, such as ECE R90 certification, should be given priority. At the same time, choose the right material according to the vehicle's use environment (such as mountainous areas, highways, etc.) to ensure the best braking effect.
Although truck brake pads are small, they are the key to ensuring transportation safety. Whether you are a fleet manager or an individual driver, you should pay attention to the maintenance and upgrade of brake pads to ensure smooth transportation.
