Product Advantage
Authoritative Certification & Proven Expertise
Backed by 15+ years of experience in automotive braking component manufacturing, our brake discs hold ISO 9001 and ECE R90 certifications—meeting strict global safety and quality standards. Rigorously tested in simulated urban, highway, and mountain driving conditions, they maintain stable performance even after 80,000+ km of use, far exceeding the average service life of ordinary brake discs. This authority ensures customers get reliable, industry-verified braking solutions.
High-Wear Resistance with Premium Materials
Crafted from high-carbon alloy steel (S45C grade) with a specialized heat-treatment process, our high-wear resistance brake discs offer 30% better wear resistance than standard alternatives. The surface is coated with a corrosion-resistant layer that prevents rusting from rain, snow, or road salt—extending the disc’s lifespan by 25%. Precision machining (tolerance ≤0.05mm) ensures tight contact with brake pads, reducing pad wear and avoiding premature replacement costs.
Superior Heat Dissipation to Prevent Brake Fade
Equipped with an optimized ventilated structure (12 curved cooling vanes), the discs achieve 25% improved heat dissipation efficiency. During continuous heavy braking (e.g., downhill driving), they can quickly reduce surface temperature from 600℃ to 350℃ in 3 minutes—effectively preventing brake fade (a common cause of reduced stopping power). Test data shows this design maintains consistent braking force even in high-temperature environments, enhancing driving safety.
Quiet & Stable Braking Experience
Our brake discs feature a mirror-finish surface (Ra ≤0.8μm) and a chamfered edge design, which minimizes friction noise between discs and pads. Real-road tests confirm braking noise is reduced to ≤55dB (equivalent to normal conversation volume), eliminating annoying squeals. Additionally, the disc’s balanced rotation (dynamic balance ≤5g·cm) reduces vibration by 18% during braking, ensuring smooth handling and improving overall driving comfort.
Easy Installation & Long-Term Warranty
Designed with a bolt-on structure, the discs require no additional modification or machining—matching standard mounting interfaces for quick, hassle-free installation (saving 30% of installation time compared to custom-fit options). To further build trust, we provide a 2-year unlimited-mileage warranty. If any quality issues arise (e.g., premature wear, deformation), our professional after-sales team offers free replacement or repair, ensuring customers’ long-term peace of mind.

Product Uses
Here are specific application scenarios of brake disc:
1.Urban Daily Commuting
Ideal for frequent stop-and-go city driving (e.g., rush hours, traffic lights). Our high-wear resistance brake discs handle 50+ daily brake cycles easily, with 80,000+ km service life (30% longer than ordinary discs). The ≤55dB quiet braking design avoids disturbing pedestrians, while the anti-corrosion coating resists rust from urban rain/splashes—backed by 15+ years of urban commuting scenario optimization.
2.Long-Distance Highway Driving
Perfect for extended highway trips with occasional high-speed braking. The 25% enhanced heat dissipation (via 12 curved vanes) cools discs from 600℃ to 350℃ in 3 mins, preventing brake fade. ECE R90-certified, they maintain stable stopping power even after 4+ hours of continuous driving, reducing safety risks for long-haul users.
3.Mountain & Hilly Road Conditions
Excels in downhill/mountainous areas with frequent heavy braking. With 800℃ maximum operating temperature (SAE J2522-tested) and 25% better heat dissipation, they avoid performance drop during repeated braking. The high-carbon steel material resists deformation under pressure, ensuring reliable braking on steep slopes—trusted by 5000+ users in mountainous regions.
4.Harsh Weather Driving (Rain/Snow/Salt)
Reliable in wet, snowy, or coastal areas. The 8-12μm phosphating coating passes 500-hour salt spray tests (ISO 9227), preventing rust from road salt or seawater. The precision-machined surface maintains tight pad contact even on wet roads, reducing skidding risks by 18% (third-party wet-brake tests)—ideal for all-weather use.
5.Commercial/High-Frequency Use
Suitable for commercial vehicles (e.g., delivery vans) with daily high-mileage use. The 30% higher wear resistance cuts replacement frequency, while the 2-year unlimited-mileage warranty lowers maintenance costs. Bolt-on installation saves 30% time, ensuring commercial fleets minimize downtime—proven by 100+ fleet clients over 5 years.
Product Operate Guide
For safety and performance, let professionals install the disc: tighten bolts to 80-100 N·m (per ISO 898-1) to prevent looseness. Check wear every 10,000km—replace if thickness drops below 18mm. Clean disc surfaces of dust/debris monthly. Pair with standard organic/semi-metallic/ceramic pads (our 15+ years of testing proves this match boosts 25% service life) for optimal braking.
