Brake Pads: The Key Defense Line for Automotive Safety
Among the numerous components of a vehicle, brake pads may seem unremarkable, but they play a pivotal role in ensuring driving safety. As the core component of the automobile braking system, they directly determine whether a vehicle can decelerate or stop in a timely and effective manner, making them a critical element that no car owner should overlook.
Structurally, brake pads generally consist of a steel plate, an adhesive thermal insulation layer, and a friction block. The steel plate undergoes anti-rust coating treatment to provide a solid support for the entire brake pad. The adhesive thermal insulation layer is made of non-heat-conductive materials, primarily designed to prevent the transfer of heat generated during braking, avoiding impacts on other components. The friction block, the key part of the brake pad, is composed of friction materials and adhesives. During braking, it comes into close contact with the brake disc or drum, generating strong friction to decelerate or stop the vehicle.
Brake pads come in various types. According to braking methods, they can be divided into brake pads for disc brakes and brake shoes for drum brakes. In terms of formulation technology, there are asbestos types, semi-metallic types, non-asbestos organic (NAO) types, etc. Asbestos brake pads were once widely used due to the high strength and heat resistance of asbestos fibers, but their hazards have gradually been recognized. Asbestos is a carcinogen whose fibers easily enter the human lungs, causing health problems. Additionally, asbestos has poor thermal conductivity, prone to causing braking fade or even failure. Semi-metallic brake pads use steel wool as reinforcing fibers, with a high metal content and strong strength, but they may cause significant wear on brake discs or drums and produce noise in low-temperature environments. However, they excel in temperature control and braking temperature, effectively aiding heat dissipation. Non-asbestos organic brake pads mainly use glass fibers, aromatic polyester fibers, etc., as reinforcing materials. Their performance is closer to that of asbestos brake pads, and they have gradually become the mainstream choice in the market, surpassing asbestos brake pads in many aspects.
Different types of brake pads are suitable for various vehicles and driving scenarios. High-performance sedans or sport utility vehicles (SUVs) typically choose metallic brake pads to meet their demand for high-strength braking performance. Ceramic brake pads, with their characteristics of high temperature resistance, excellent heat dissipation, and strong wear resistance, are suitable for vehicles in various climatic conditions. Composite brake pads integrate the advantages of metallic and ceramic types, suitable for models that pursue a balance between performance and economy. Semi-metallic brake pads combine the strengths of metallic and ceramic types, making them a good choice for vehicles that require good braking effect while hoping to reduce metal waste emissions. Non-metallic brake pads, due to their environmental friendliness, light weight, and low noise, are mostly used in motorcycles and light vehicles.
In daily driving, vehicle owners should pay attention to the wear condition of brake pads. When the thickness of the friction block approaches the limit value (generally 2-3 millimeters), it needs to be replaced promptly. Otherwise, it may lead to reduced braking efficiency or even complete failure, seriously endangering driving safety. In addition, if abnormal noise occurs during braking, the braking distance significantly increases, or the vehicle vibrates obviously while braking, these may indicate problems with the brake pads, and timely inspection and maintenance are required.
