Understand Brake Pads in One Article: The Unsung Hero of Automotive Safety
Among the many components of a vehicle, brake pads, though seemingly ordinary, play a crucial role in ensuring driving safety. As the core component of the braking system, the performance of brake pads directly determines a vehicle's braking effect and is related to the safety of every trip. Next, let's delve into the knowledge about brake pads.
一,Working Principle
The working principle of brake pads is based on friction. When the driver presses the brake pedal, the hydraulic device in the braking system transmits pressure to the brake caliper, causing the brake pads to tightly press against the rotating brake disc. Through the friction between the two, the vehicle's kinetic energy is converted into heat energy, achieving the purpose of deceleration or stopping. This process may seem simple, but it places extremely high demands on the performance and quality of brake pads.
二,Classification and Characteristics
(一)Classification by Brake Type
1. Disc Brake Pads: The most common type today, widely used in various passenger vehicles and some commercial vehicles. It features fast braking response and good heat dissipation, adapting to frequent braking needs. In urban roads where vehicles start and stop frequently, disc brake pads can quickly and effectively perform braking to ensure driving safety.
2. Drum Brake Shoes: Usually used in some light commercial vehicles and partial low-end models. Drum brakes have a relatively simple structure and lower manufacturing cost, but their heat dissipation performance is poor. Continuous braking easily causes thermal fade, leading to reduced braking effect.
3. Truck Linings: Due to their heavy load and complex driving conditions, trucks have more stringent requirements for brake pad performance. Linings need higher wear resistance and heat resistance to meet the braking needs of heavy-duty vehicles under special conditions such as long downhill slopes.
(二)Classification by Material
1. Semi-Metallic Brake Pads: Contain 30%-65% metal components such as copper and iron. They have excellent heat resistance and wear resistance, capable of withstanding high braking pressure, often used in high-performance vehicles or heavy-duty vehicles. However, they also have drawbacks, such as loud noise during braking and easy dust generation, affecting the environment and wheel cleaning.
2. Ceramic Brake Pads: Made of ceramic fibers, fillers, and adhesives. These pads feature low noise, less dust, and smooth braking, providing drivers with a more comfortable braking experience, suitable for mid-to-high-end models for daily driving. However, ceramic brake pads have relatively high costs and prices.
3. Low-Metallic Brake Pads: With a metal content between semi-metallic and ceramic types, they balance wear resistance and quietness, making them a more balanced choice that meets the needs of most ordinary vehicles.
4. Organic Non-Asbestos (NAO) Brake Pads: Made of eco-friendly materials like glass fiber and carbon, they offer good noise and dust control, meeting environmental requirements. However, their heat resistance is slightly inferior, making them more suitable for mild driving environments such as urban roads.
三,How to Judge When to Replace Brake Pads
1. Check Thickness: A brand-new brake pad is generally about 1.5 cm thick. When the thickness is visually reduced to 1/3 of the original (about 5 mm or less), frequent inspections are needed, and replacement should be prepared. Additionally, there are usually raised small marks on both sides of the brake pad. When the pad wears down to the same level as these marks (2-3 mm), it means the limit has been reached and must be replaced immediately.
2. Listen for Sounds: If a sharp metallic scraping sound (similar to nails scratching a blackboard) is heard during braking, it is likely the wear indicator of the brake pad alarming, indicating that the friction material is almost exhausted and needs urgent replacement. Otherwise, continued use may damage the brake disc and increase maintenance costs.
3. Sense Braking Pedal Feel: If the brake feels softer than before during driving, or the braking distance significantly lengthens and the vehicle cannot stop effectively, it may also signal severe wear of the brake pads. At this point, the brake pads should be inspected and replaced promptly to ensure driving safety.
