This article will analyze the core knowledge of the brake pad industry from the dimensions of material characteristics, selection and adaptation, and industry trends, providing professional references for customers' selection and application.
I. Classification and Performance Characteristics of Core Brake Pad Materials
The performance of brake pads is determined by friction materials. At present, the mainstream materials in the market are divided into six categories. Different materials have significant differences in high temperature resistance, noise reduction, wear resistance and cost, adapting to different vehicle models and usage scenarios, and serving as the core basis for selection.
1. Semi-metallic brake pads: The mainstream model in the market with a metal content of 30%-65% and high temperature resistance up to over 400℃. They feature wear resistance and affordable cost, suitable for frequent braking scenarios such as online car-hailing and commercial vehicles, as well as daily commuting of family cars. The disadvantages are easy abnormal noise at low temperatures and slightly fast wear on brake discs, making them a cost-effective choice for commercial vehicles and economical passenger cars.
2. Ceramic brake pads: The mainstream high-end model, composed of ceramic fibers and non-metallic mineral composites, with high temperature resistance up to over 650℃, a 70% reduction in dust emission, excellent noise reduction effect and a service life of 50,000-100,000 kilometers. Suitable for mid-to-high-end passenger cars, new energy vehicles and scenarios with high requirements for braking stability such as high-speed driving and mountain roads. The only shortcoming is slightly weak braking force at low temperatures, and the price is 30%-50% higher than that of semi-metallic ones.
3. Low-metallic brake pads: A balanced performance choice with a metal content of less than 30% and a 30% reduction in noise compared with semi-metallic ones, achieving an optimal balance between braking effect and brake disc wear. Suitable for mild driving scenarios such as urban commuter cars with a service life of 30,000-50,000 kilometers, it is the first choice for car owners with a limited budget.
4. Carbon fiber brake pads: Track-level performance model with high temperature resistance up to over 800℃, 50% higher braking efficiency than ordinary materials, light weight and extreme thermal stability. Only suitable for high-performance sports cars and professional track scenarios, and need to be matched with special brake discs, with low cost performance for daily use.
5. Non-metallic brake pads: Special model for micro electric vehicles, composed of pure organic fibers and resin composites, with zero metal dust and an ultimate noise reduction effect. However, the high temperature resistance is only about 300℃ and the friction coefficient is low, suitable for low-speed short-distance commuting of micro electric vehicles.
6. Carbon-ceramic brake pads: Exclusive model for super sports cars, made of carbon fiber and ceramic composite technology, with high temperature resistance over 1000℃, effectively reducing unsprung mass and improving handling. The disadvantage is extremely high cost, with the replacement cost of a full set exceeding 50,000 yuan, only suitable for super sports car track scenarios.
Core selection suggestions: Choose semi-metallic brake pads for commercial vehicles/trucks to adapt to heavy-duty frequent braking; prioritize ceramic/low-metallic brake pads for family cars, taking into account noise reduction and durability; choose non-metallic brake pads for new energy micro vehicles; avoid ceramic brake pads in severe cold areas in the north, and prioritize ceramic brake pads in mountainous areas in the south.
II. Core Principles for Brake Pad Purchase and Replacement
Brake pads are life-saving parts. Improper purchase or delayed replacement may lead to potential safety hazards such as brake failure and brake disc wear. It is necessary to strictly follow the principles of adaptability and timeliness.
(1) Three Signals Indicating Immediate Replacement
1. Harsh metal friction sound during braking: Brake pads are built with wear warning pieces. When the friction material is only 3-5mm left, the warning pieces contact the brake disc to produce abnormal noise. Replacement at this time can avoid abrasion to the brake disc (doubling the maintenance cost); if it is a dull thud, it is necessary to check the installation or brake disc deformation.
2. Soft brake pedal and longer braking distance: After the friction material becomes thin, pressure transmission fails and braking efficiency decreases, which is a high-risk signal and requires immediate inspection and replacement.
3. The thickness of friction material is less than 3mm / driving over 30,000 kilometers: The thickness of new brake pads is 10-12mm. Attention should be paid when worn to 1/3. The service life of family cars for urban commuting is 15,000-20,000 kilometers, and it can be extended to 30,000-40,000 kilometers for mostly high-speed driving. Even if the thickness is up to standard after the expiration date, the material will age and harden, and the braking performance will drop significantly.
(2) Two Core Purchase Parameters Must Be Consistent with the Original Vehicle
1. Model specifications: Must match the vehicle's brake caliper type (single/multi-piston), brake disc size and back plate hole position. Provide the vehicle model year + displacement + driving mode when purchasing, and reject universal models (reduced friction area and decreased braking performance).
2. Friction coefficient: Determines the braking force and must match the vehicle weight. Choose 0.35-0.45 (FF/GG grade) for family cars (1.2-1.8 tons); choose 0.40-0.50 (HH grade) for SUV/MPV (1.8-2.5 tons); do not blindly pursue high friction coefficients (such as racing JJ grade), which is easy to cause overheating and rapid wear of brake discs.
(3) Three Tips to Avoid Inferior Products
1. Check the appearance: High-quality brake pads have firm adhesion between friction materials and back plates, no air bubbles or cracks, and no rust or burrs on the back plates;
2. Smell the odor: High-quality products adopt environmental protection formulas with only a slight material odor, while inferior products use recycled materials with a pungent burning odor when heated;
3. Recognize certifications: Prioritize products with ECE R90, CCC and other certifications and brand quality assurance (1-2 years), and reject three-no products (no brand, no certification, no after-sales).
III. Current Development Status and Core Trends of the Brake Pad Industry
In recent years, with the electrification and intelligent upgrading of the global automobile industry and the increasingly stringent environmental regulations, the brake pad industry has shown the development characteristics of high-endization, environmental protection and customization, with a steady expansion of market scale.
1. Sustained market scale growth: The scale of China's brake pad market has exceeded 24 billion yuan in 2025, with a compound annual growth rate of 7.3% from 2021 to 2025, and it is expected to exceed 32 billion yuan by 2030. The core driving force for growth comes from the increase in automobile ownership (the number of civil motor vehicles in China exceeded 340 million in 2025) and the extension of the average vehicle age (6.9 years), driving the continuous release of replacement demand in the after-sales market.
2. High-end upgrading of product structure: Semi-metallic brake pads still dominate the market (about 45%), widely used in commercial vehicles and economical passenger cars; the market share of ceramic brake pads is rising rapidly (reaching 19.5% in 2024), with the penetration rate increasing year by year in mid-to-high-end passenger cars and new energy vehicles, and it is expected to break through 25% by 2027, becoming the core engine of industry growth.
3. New energy vehicles spawn customized demand: The penetration rate of new energy vehicles in China exceeded 40% in 2025. Their energy recovery system reduces the frequency of mechanical braking use by 30%-40%, putting forward higher requirements for brake pads in terms of low noise, low dust, corrosion resistance and high temperature stability, and promoting the R&D of special products such as ceramic-based composite brake pads.
4. Environmental regulations force technological upgrading: The European Union has implemented the access standard of brake pad copper content lower than 5%, and China is expected to introduce similar environmental specifications in 2026. Copper-free/low-copper formula, low dust and recyclability have become the focus of brake pad R&D, and green manufacturing has become the core competitiveness of enterprises.
5. Significant differentiation in demand between passenger cars and commercial vehicles: Passenger car brake pads account for 66%, focusing on comfort and noise reduction; commercial vehicles account for 34%. Due to the demand for heavy-duty transportation, they maintain rigid demand for semi-metallic brake pads with high wear resistance, heat fade resistance and long service life, which is a stable demand sector of the brake pad market.
IV. Core Competitive Elements of the Brake Pad Industry
As a core segment of auto parts, the brake pad industry takes technology, quality and certification as the core competitive barriers. Especially in the overseas market, compliance and product consistency are the basis for cooperation:
1. Technological R&D: The formula of friction materials is the core, which needs to take into account multiple indicators such as stable friction coefficient, high temperature resistance and low noise, and adapt to the customized demand of different scenarios such as new energy vehicles and commercial vehicles at the same time;
2. Quality control: The production of brake pads requires high-precision molding and strict performance testing (high temperature resistance, wear resistance, braking response) to ensure product consistency and avoid braking failures caused by batch differences;
3. International certification: To enter overseas markets such as Europe, America and Southeast Asia, it is necessary to pass ECE R90 (EU), DOT (US), CCC (China) and other certifications to meet local environmental and safety standards;
4. Industrial chain integration: The prices of raw materials such as copper, resin and friction modifiers fluctuate greatly. Enterprises with vertical integration capabilities of the supply chain can effectively control costs and ensure stable production capacity.
