Essential Industry Knowledge of Brake Pads

As a critical component ensuring vehicle safety, brake pads play an irreplaceable role in the automotive braking system. Understanding their core knowledge is vital for both professional procurement and daily vehicle maintenance.

Classification by Material

Brake pads are primarily categorized by material, each with distinct performance characteristics to meet diverse application needs:

• Semi-metallic Brake Pads: Widely used as original equipment, featuring fine metal fibers and particles for enhanced strength. They excel in temperature control and heat dissipation but may produce noise at low temperatures with a friction coefficient of around 0.38. Cost-effective and suitable for commercial vehicles and daily commuting cars.

• Low-metallic Brake Pads: Similar in appearance to semi-metallic types but with lower metal content. They reduce brake drum wear and noise effectively, though their service life is slightly shorter. Ideal for SUVs and MPVs requiring stable load-bearing performance.

• Non-Asbestos Organic (NAO) Brake Pads: Free of metal components, made from aramid, glass fiber, and other organic materials. Offering a short break-in period (approximately 200km) and low noise (below 65 decibels), they are perfect for urban commuter vehicles. Performance varies by manufacturer's formula and craftsmanship.

• Ceramic Brake Pads: Composed of ceramic fibers mixed with other fibers and solidified by organic binders. Boasting high hardness, excellent wear resistance, low dust emission, no hub corrosion, and quiet operation, they deliver superior thermal fade resistance with a maximum operating temperature up to 800℃. Popular in European, American, and Japanese markets, suitable for high-performance cars and luxury family vehicles.

• Carbon-Ceramic Composite Brake Pads: Ultra-lightweight (60% lighter than steel) and extremely heat-resistant (maintaining performance at 1200℃), with a service life exceeding 100,000 kilometers. Primarily used in top-tier supercars and racing vehicles due to their high cost.

Core Performance Indicators

• Wear Resistance: Determines service life and replacement frequency, balanced with braking force to avoid excessive brake disc wear. Ceramic and semi-metallic types offer excellent durability for different scenarios.

• Braking Force: Reflects friction intensity between pads and discs, affecting braking response and distance. High-metal-content pads provide strong immediate braking, while ceramic pads offer linear, stable performance.

• Thermal Fade Resistance: Measures performance stability at high temperatures. Critical for mountain driving or heavy loads, with high-performance pads (ceramic or racing-grade) maintaining effectiveness above 400℃.

• Noise Level: Related to material hardness and surface flatness. Ceramic pads and those with multi-layer shock absorption structures minimize noise.

• Dust Emission: Metal-based pads produce more adherent dust, while ceramic pads generate minimal, easy-to-clean debris, reducing maintenance costs.

Industry Standards and Regulations

Global brake pad production and application are strictly regulated by international and regional standards:

• International Standards: Include UNI EN 1664:2000 (Italy), NS 737:1955 (Norway), and VDI 3973-1990 (Germany), covering material specifications, dimensions, and safety requirements.

• Regional Standards: US Title 49 CFR 393.47 specifies minimum thickness requirements (e.g., 3.2mm for air disc brakes, 1.6mm for hydraulic disc brakes). China's GB5763-2008 details technical requirements and inspection procedures for automotive brake linings.

• Environmental Regulations: EU REACH restricts harmful substances in friction materials, and 2026 EU brake dust emission standards drive eco-friendly formula development. North America has included brake particles in air quality monitoring.

Market Trends and Development Directions

• Market Growth: The global brake pad market is projected to reach $9.13 billion in 2025 and $12.11 billion by 2029, with a CAGR of 7.3%, driven by expanding global vehicle fleets and safety-focused automotive design.

• Technology Innovation: Key trends include low-dust formulations, high-grade composite materials, wear-monitoring sensor integration, and noise reduction technologies. Smart brake pads with predictive maintenance systems have a 12% penetration rate in 2025.

• New Energy Vehicle Adaptation: Electric and hybrid vehicles demand specialized brake pad designs, boosting low-metallic formula demand (projected 41% market share by 2030).

• Sustainable Development: Non-copper and bio-based materials are gaining traction, with R&D investment in eco-friendly formulas growing by 42%.
