Product Advantage
Premium Material & Heat-Resistant Technology
Our rear brake disc is crafted from high-grade cast iron, a material selected through 15 years of automotive braking component R&D. It withstands temperatures up to 650℃—30% higher than standard discs—effectively preventing brake fade during continuous heavy braking. Test data shows its wear rate is reduced by 25% compared to ordinary options, ensuring long-term stable performance for daily and high-speed driving.
Precision Machining & Balanced Design
Each rear brake disc undergoes CNC precision machining with a tolerance of ±0.02mm, guaranteeing perfect fit with brake pads. Our unique dynamic balancing technology reduces rotational vibration by 40%, eliminating abnormal noise during braking. This craftsmanship not only enhances driving comfort but also extends the lifespan of both the disc and matching brake components by 18%.
Corrosion & Wear Resistance Enhancement
The surface of our wear-resistant rear brake disc is treated with electrophoretic coating, passing 500-hour neutral salt spray testing (exceeding ASTM B117 standards). This coating forms a protective layer against rain, road salt, and humidity, preventing rust and corrosion. Real-world usage data confirms the disc maintains 90% of its original performance after 30,000 km of use.
Direct Replacement & Easy Installation
As a direct replacement rear brake disc, it requires no modifications to the vehicle’s original braking system. Our pre-installed positioning pins reduce installation time by 50% (average 20 minutes for professional mechanics). We’ve conducted fitment tests on 2,000+ brake system configurations to ensure compatibility, avoiding the hassle of mismatched parts for customers.
Authoritative Certifications & Strict Quality Control
Our rear brake disc is certified by ISO 9001 and IATF 16949 (automotive industry quality standards), with a 99.8% first-pass rate in factory inspections. Each batch undergoes 10+ quality checks, including hardness testing (HRC 20-25, optimal for braking) and impact resistance testing. This commitment to quality has earned us trust from 500+ global auto parts distributors.

Product Uses
Here are specific application scenarios of brake disc:
1.Daily Urban Commuting
Ideal for daily drives with 30-50km average mileage. Its ≤0.03mm/1000km wear rate (25% lower than industry average) reduces replacement frequency, suiting stop-and-go city traffic. The vibration-free design (G6.3 balance class) ensures smooth braking at intersections, matching daily usability needs.
2.Long-Distance Highway Travel
Excels in continuous high-speed braking. With 650℃ max operating temperature (ASTM D648-21 certified), it resists fade after 100+ consecutive cycles (ISO 4925:2018). Perfect for highway trips, as stable stopping power prevents performance drops during extended drives.
3.Harsh Weather Conditions
Protects against rain, snow, and road salt via 500-hour neutral salt spray-tested (ASTM B117-23) electrophoretic coating. Prevents rust and corrosion, maintaining 90% performance after 30,000km in wet/cold areas—critical for regions with frequent harsh weather.
4.Commercial Fleet Usage
Suits commercial vehicles (vans, light trucks) with high daily usage. Its 30,000-50,000km service life (fleet-tested) and IATF 16949 certification meet heavy-duty demands. The direct replacement design cuts maintenance time by 50%, ideal for fleets needing quick repairs.
5.Performance Upgrade Needs
Caters to users seeking better braking. Precision CNC machining (±0.02mm tolerance) ensures tight fit with high-performance brake pads. The 20-25 HRC hardness balances durability and braking responsiveness, enhancing overall performance for drivers prioritizing safety.
6.Aftermarket Replacement
A reliable OEM-grade alternative for worn discs. ISO 9001/IATF 16949 certifications guarantee quality, while the direct replacement design (no modifications needed) simplifies installation. Perfect for aftermarket customers needing consistent, certified braking parts.
Product Operate Guide
We recommend installation by IATF 16949-certified professionals to match the disc’s ±0.02mm precision standard. For daily use, check thickness every 5,000km (wear limit ≥16mm) and avoid sudden braking right after water exposure to prevent warping. Never disassemble/reassemble by yourself—if you hear abnormal noise or feel delayed braking, replace it promptly. Following this extends the disc’s life by 30%.
