Product Introduction
A21-3501090 Ceramic-Enhanced Reliable Premium Brake Pad for Chery
With over 10 years of experience in auto parts manufacturing, we present the A21-3501090 brake pad—engineered for reliable braking performance. It meets ECE R90 (the global benchmark for brake safety), ensuring compliance with strict quality standards.
Boasting a friction coefficient of 0.38-0.42 (optimal for stable stopping power), it resists fade even at 350℃. Its ceramic-enhanced formula extends service life by 15% vs. industry averages, while reducing brake noise by 20dB. Each unit undergoes 3 rounds of quality inspections to guarantee consistent performance.
Product Advantage
1. Ceramic-Enhanced Formula for Low Noise & Stable Friction
Our ceramic brake pads adopt a proprietary ceramic-silica composite formula, developed through 300+ road test iterations. It maintains a friction coefficient of 0.38-0.42 (the optimal range for safe braking) across temperatures from -30℃ to 380℃, with a fluctuation rate of only ±0.02. This design reduces brake noise by 25dB compared to standard metallic pads, and cuts down on brake dust by 40%—solving two major pain points for users.
2. ECE R90 Certified for Global Safety Compliance
As ECE R90 certified brake pads, each unit passes rigorous testing by SGS (a leading global inspection agency), including dynamometer performance tests and environmental durability tests. Our certification compliance rate has remained 100% for 8 consecutive years, far exceeding the industry average of 92%. This ensures the product meets safety standards in 50+ countries, eliminating import barriers for your overseas customers.
3. 20% Longer Service Life Than Industry Averages
We enhance durability by adding high-temperature-resistant fibers to the pad matrix, which reduces wear rate by 18%. Real-vehicle data shows the A21-3501090 pad lasts up to 65,000 km, while the industry average for similar high-performance brake pads is 54,000 km. For fleet users or frequent drivers, this translates to 1-2 fewer pad replacements per year, lowering their total ownership cost.
4. Multi-Layer Backing Plate for Vibration Reduction & Heat Dissipation
The backing plate features a 3-layer structure: a steel base layer, a heat-insulating ceramic coating (thickness 0.8mm), and an anti-vibration rubber buffer. This design blocks 60% of the heat generated during braking from transferring to the caliper, reducing caliper failure risk by 35%. It also absorbs 70% of braking vibrations, further enhancing driving comfort.
5. 5-Step Quality Inspection with 99.8% Pass Rate
Every A21-3501090 brake pad undergoes a 5-step inspection process: raw material screening, semi-finished product dimension checking, friction coefficient testing, high-temperature aging test, and final assembly inspection. Our annual product qualification rate is 99.8%, with a post-sales failure rate of less than 0.5%—backed by a 12-month global warranty to strengthen customer trust.

Product Uses
Here are specific application scenarios of brake pad:
1. Urban Daily Commuting
Ideal for stop-and-go urban driving (average 30+ starts/stops per hour), its ceramic formula reduces brake noise to ≤55dB (per DIN 40050-2) — avoiding disturbance in residential areas. The 40% lower brake dust (vs. metallic pads) also means less frequent wheel cleaning, saving users 1-2 hours of maintenance monthly.
2. High-Speed Long-Distance Travel
Certified to ECE R90, it maintains stable friction (0.38-0.42 coefficient) even during 120km/h emergency braking. It resists fade at 380℃ continuous operation, preventing performance drop on long highways. Real tests show no significant wear after 1,500km of high-speed driving — ensuring consistent safety.
3. Mountainous & Hilly Road Driving
For roads requiring frequent downhill braking, its high-temperature-resistant fibers lower wear rate by 18%. It handles 5+ consecutive steep downhill braking cycles (10° slope, 60km/h) without overheating, extending service life to 65,000km — 20% longer than industry averages for hilly-area use.
4. Commercial Fleet Operations (Logistics/Van Services)
Designed for high-frequency use (8-10 hours daily), it cuts maintenance frequency by 30%: fleets report replacing pads only once every 10 months (vs. 7-8 months for standard pads). The 99.8% pre-delivery qualification rate also reduces unexpected downtime, supporting fleet efficiency.
5. Extreme Temperature Environments
Adaptable to -30℃ (cold winters) to 380℃ (hot summers) conditions. In -30℃ low-temperature tests, its friction coefficient fluctuation is ≤±0.02 — avoiding weak braking in freezing weather. For hot regions, it prevents brake fade even after 20 minutes of continuous use at 350℃.
Product Operate Guide
Backed by 12 years of auto brake service experience, follow these steps to maximize performance (aligned with ECE R90 usage standards). First, run a 300-500km break-in period: avoid sudden hard braking, keep gentle stops to let friction material adapt. Inspect every 5,000km—replace if friction material thickness drops below 3mm. Avoid frequent hard braking to maintain 65,000km service life. Contact us for troubleshooting if abnormal noise occurs post-installation.
