Product Introduction
A11-3501075 Anti-Fade Rust-Proof Noise-Free Brake Disc for Chery
Our Brake Disc is built on 15+ years of expertise in automotive brake system engineering, ensuring professional-grade reliability. It adheres to strict ISO 9001 and TS 16949 certifications—industry benchmarks for quality—guaranteeing compliance with global standards.
Crafted from high-strength cast iron, it withstands temperatures up to 650℃ for stable braking even under heavy use, with a service life 30% longer than average OEM equivalents. Its precision-machined surface minimizes vibration and accelerates heat dissipation, enhancing driving safety. Each unit passes 3 rounds of quality checks, delivering consistent, durable performance.
Product Advantage
High-Strength Material & Heat Resistance
Our brake disc is made of high-purity cast iron with added manganese alloy, developed based on 18 years of automotive brake component R&D experience. It meets ISO 9001 and TS 16949 standards, and can withstand continuous high temperatures up to 680℃—20% higher than ordinary brake discs. This ensures no deformation or cracking during long-term heavy braking, greatly improving driving safety.
Precision Machining for Stable Performance
Each brake disc undergoes 5-axis CNC precision machining, with a surface roughness of Ra≤0.8μm. This reduces friction noise by 35% compared to standard products and ensures uniform contact with brake pads. The optimized vent structure accelerates heat dissipation by 40%, preventing brake fade caused by overheating. It also minimizes vibration during braking, enhancing driving comfort.
Long-Life & Wear-Resistant Design
We adopt a special nitriding surface treatment process for the brake disc, which increases its surface hardness to HV850—doubling the wear resistance of traditional brake discs. Test data shows its service life reaches 80,000 km, 30% longer than average OEM brake discs. This reduces replacement frequency for users, lowering long-term use costs.
Strict Quality Inspection & Global Compatibility
Every brake disc passes 4 rounds of quality checks (dimensional inspection, hardness test, high-temperature endurance test, dynamic balance test) with a qualification rate of 100%. It is a professional high-performance brake disc compatible with multiple automotive brake systems, and we provide 12 months of after-sales warranty. Our annual output exceeds 500,000 units, trusted by customers in 30+ countries.

Product Uses
Here are specific application scenarios of brake disc:
1.Daily Urban Commuting
Ideal for frequent start-stop driving in cities. With ≤15% thermal fade rate (meets SAE J2522), it maintains stable braking even after repeated use in traffic jams. Its precision machining (Ra ≤0.8μm) also reduces noise, enhancing driving comfort.
2.Long-Distance Highway Driving
Suitable for extended highway trips. Boasting ≥80,000 km service life, it minimizes replacement frequency during long journeys. The high-heat resistance (up to 680℃) prevents performance drop under continuous high-speed braking.
3.Mountain/Hilly Road Driving
Perfect for steep slope conditions. Its HT300 cast iron material (with Mn additive) and 180-220 HB hardness resist deformation from frequent downhill braking. The optimized vent structure accelerates heat dissipation by 40%, avoiding brake failure risks.
4.Adverse Weather Conditions (Rain/Snow)
Reliable in wet or snowy environments. The smooth surface (Ra ≤0.8μm) reduces water film formation, ensuring consistent friction with brake pads. It also meets ISO 10487 fitting standards, preventing caliper jamming in low temperatures.
5.Light Commercial Vehicle Use
High tensile strength (≥300 MPa, complies with ISO 6892-1) withstands heavy-load braking. The 100% qualified 4-stage inspection ensures durability for daily cargo transportation.
6.Aftermarket Performance Upgrades
Suitable for users seeking brake upgrades. With G6.3 dynamic balance grade, it reduces vibration at high speeds. It’s compatible with most OEM brake systems, making it a cost-effective choice for performance enhancement.
Product Operate Guide
For proper use: 1. Install per ISO 10487 standards—tighten mounting bolts to 25-35 N·m (avoids loose rotation). 2. After installation, perform 5-8 gentle brake tests to ensure alignment. 3. Maintain regularly: Check wear every 10,000 km; replace if thickness decreases by over 3mm. 4. Keep the disc surface clean—wipe off dust/oil monthly to prevent braking noise or friction loss.
