Analysis of Core Brake Pad Types
The material of brake pads determines braking safety, comfort and durability. The four mainstream types differ significantly in applicable scenarios and should be selected based on actual needs.
I. Semi-Metal Brake Pads: Cost-Effective Choice for Family Cars
Core Technology: Metal powder accounts for 30%-60%, complying with the GB 5763-2018 standard; friction coefficient ranges from 0.35 to 0.45, temperature resistance is 300-500℃, a set (4 pieces) costs 200-500 yuan, and service life is 40,000-60,000 kilometers.
Applicable Scenarios: Family cars such as Volkswagen Lavida and Toyota Corolla, used for daily urban commuting with 20-50 kilometers per day.
Notes: May produce abnormal noise at low temperatures; need to be matched with DOT4+ brake fluid; annual wear of brake discs is 0.3-0.5mm.
II. Ceramic Brake Pads: First Choice for High-End Cars (Quiet and Wear-Resistant)
Core Technology: Metal-free formula, heat dissipation improved by 40%, temperature resistance exceeds 600℃, friction coefficient ranges from 0.32 to 0.40; a set costs 800-1500 yuan, service life is 60,000-80,000 kilometers, and abnormal noise rate is less than 0.5%.
Applicable Scenarios: High-end cars such as BMW 3 Series and Mercedes-Benz GLC, or SUVs (e.g., Toyota Highlander) frequently used for high-speed driving or in mountainous areas.
Notes: Braking response is slightly slow below 0℃; initial cost is high, but cost per kilometer is equivalent to that of semi-metal brake pads.
III. NAO Brake Pads: Economical Choice for Miniature Mobility Vehicles
Core Technology: Mainly made of organic materials, 20% lighter in weight; friction coefficient ranges from 0.30 to 0.38, a set costs 100-300 yuan, and wear on brake discs is extremely small.
Applicable Scenarios: Miniature new energy vehicles such as Wuling Hongguang MINI, used for short-distance daily commuting with 10-20 kilometers per day.
Critical Limitations: Temperature resistance is below 300℃, prone to thermal fading; not allowed for high-speed driving or full-load use; service life is only 30,000-40,000 kilometers.
IV. Low-Metal Brake Pads: Balanced Choice for SUVs/MPVs
Core Technology: Metal accounts for 10%-20, with lubricant added; friction coefficient ranges from 0.40 to 0.50, temperature resistance is 550℃, a set costs 400-800 yuan, and service life is 50,000-70,000 kilometers.
Applicable Scenarios: Vehicles such as Honda CR-V and Buick GL8, suitable for full-load use and road conditions with many slopes in mountainous areas.
Notes: Requires a 500-kilometer running-in period; not suitable for small cars (prone to brake "nodding").
