Product Introduction
S21-3501080 High-performance Asbestos-free Low-Vibration Brake Pad for Chery
The S21-3501080 brake pad is designed for stable, high-performance braking, backed by our 18-year expertise in auto brake systems. It meets ECE R90 certification—an international standard for brake safety—ensuring compliance with global market requirements.
Crafted from asbestos-free, low-metallic composite materials, it delivers a consistent friction coefficient of 0.38-0.42 (within ISO 815 standards) for smooth stopping power. Rigorous testing shows its service life is 12% longer than industry averages, while reducing brake noise by up to 25dB.
Ideal for daily commuting and light commercial use, it balances durability, safety, and environmental friendliness, making it a reliable choice for brake system replacements.
Product Advantage
1. ECE R90 & ISO 815 Dual Certification for Absolute Safety
This brake pad has passed the rigorous ECE R90 certification—a mandatory standard for global automotive safety—and meets ISO 815 friction performance requirements. Its asbestos-free low-metallic composite material not only complies with EU environmental regulations but also maintains a stable friction coefficient of 0.38-0.42 in -30℃ to 300℃ extreme temperatures, avoiding brake failure caused by coefficient fluctuations.
2. 15% Longer Service Life Than Industry Average
After 5,000+ simulated urban road brake tests (including frequent start-stop and high-speed deceleration), the S21-3501080 brake pad shows only 0.8mm average wear, which is 15% lower than the industry average wear rate. The reinforced steel backing plate with anti-rust coating also extends the product’s overall service life by 12 months, making it a cost-effective choice for long-lasting brake pads for commercial use.
3. Low-Noise & Low-Vibration Braking Experience
We optimize the pad’s surface groove design and add a high-density noise-reducing rubber layer between the friction material and backing plate. Test data shows that this design reduces brake noise by up to 28dB (from 75dB to 47dB) during normal braking, far below the 60dB industry noise limit. It also reduces brake vibration amplitude by 12%, ensuring a smooth and quiet driving experience for low-noise automotive brake pads users.
4. 99.8% Production Qualification Rate & Strict Quality Control
Our automated production line (with 12 precision inspection stations) ensures a 99.8% one-time qualification rate for the S21-3501080 brake pad. Each batch of products undergoes random sampling for shear strength testing (minimum 7MPa, exceeding the 5MPa industry standard) and high-temperature durability testing. We also provide a traceable production report for each order, strengthening customer trust in ECE R90 certified brake pads.
5. Wide Compatibility & Customized Adaptation Support
Based on our database of 5000+ brake system models, the S21-3501080 brake pad is designed with a universal mounting structure, compatible with multiple vehicle platforms without modifying the brake caliper. For special needs, we offer customized friction material formulas (adjusting friction coefficient or wear resistance) within 7 working days, supported by our professional engineering team with 10+ years of experience.

Product Uses
Here are specific application scenarios of brake pad:
1. Urban Daily Commuting
Ideal for users facing frequent start-stops (average 300+ cycles/day). Its low-metallic composite material reduces wear by 15% vs. industry averages, avoiding frequent replacements. The noise-reducing design keeps braking sound ≤47dB, far below the 60dB urban noise limit, ensuring a quiet ride amid city traffic.
2. Light Commercial Transportation
Suits short-haul delivery or small cargo vehicles (daily operation 12+ hours). Its stable friction coefficient (0.38-0.42) handles light loads without performance drop. The 480-hour salt spray-tested anti-rust backing plate resists corrosion from road salts, extending service life by 12 months for high-frequency commercial use.
3. Mountain/Hilly Road Conditions
Perfect for areas with long downhill sections. It withstands 300℃ continuous high temperatures (1000-cycle test without deformation) and uses 12% copper fiber for heat dissipation, preventing brake fade. The asbestos-free formula maintains consistent braking force even on 10km+ downhill slopes, complying with ISO 815 standards.
4. Low-Temperature Frigid Regions
Reliable in -30℃ to 0℃ environments. Unlike ordinary pads that harden and lose friction in cold, it retains a ≥0.38 coefficient, ensuring responsive braking on icy roads. The high-temperature adhesive layer also avoids delamination caused by extreme temperature changes, certified for cold-climate use.
5. High-Frequency Brake Scenarios
Fits parking lot shuttles or logistics park transporters (500+ daily brakes). Its wear rate (≤0.12mm/1000 cycles) ensures long-term use, while the optimized groove design expels dust and debris, reducing brake jitter. This makes it a cost-effective choice for scenarios requiring repeated, short-distance braking.
Product Operate Guide
Based on 18 years of auto brake installation experience and ECE R90/ISO 815 standards, follow these steps to ensure optimal performance and safety.
Before installation, confirm the pad model matches (S21-3501080) and clean the brake caliper contact surface—this reduces 90% of abnormal noise risks. Tighten the mounting bolts to 25-30 N·m (per SAE J2784) to avoid over-tightening damage.
For the first 200km after installation, use mild braking (avoid sudden stops) to break in the pad; this boosts its service life by 15%. Check the pad thickness every 5000km—replace it when the friction layer is below 3mm.
