Every batch undergoes strict factory audits, with a 99.8% qualification rate, ensuring consistent compliance with industry safety requirements and winning trust from global clients.
High-Grade Material for Enhanced Durability
Crafted from premium cast iron alloy with added manganese and chromium, our brake disc reduces wear rate by 35% compared to ordinary products. It resists corrosion from road salt and moisture, maintaining structural integrity even after 50,000+ km of use. This durability makes it a cost-effective choice for long-term automotive maintenance.
Optimized Heat Dissipation to Prevent Brake Fade
Featuring a unique vane structure (18-24 curved vanes) and precision-machined surface, our brake disc enhances heat dissipation efficiency by 40%. Even in extreme conditions (e.g., continuous downhill braking or high-speed driving), it keeps temperature below 350℃, reducing brake fade risk by 25% and ensuring stable stopping power.
Precision Fit & Easy Installation
With CNC machining technology (tolerance ±0.02mm), our brake disc achieves a 98% fit accuracy with compatible automotive brake systems. It eliminates the need for additional adjustments during installation, cutting labor time by 15% for repair shops. The standardized mounting holes also match most mainstream brake calipers, improving versatility.
Improved Braking Performance for Safety
Through dynamic balance testing (residual unbalance ≤5g·cm), our brake disc minimizes vibration during braking, reducing noise by 20%. It shortens braking distance by 15% on dry roads (at 100km/h) and enhances stability by 25% on wet roads, providing drivers with reliable safety support in various driving scenarios.

Product Uses
Here are specific application scenarios of brake disc:
1.Urban Daily Commuting
Ideal for frequent start-stop urban driving. With a wear rate of ≤0.08mm/10,000km and 20% noise reduction, it endures daily brake usage (30+ times/hour) without rapid wear. Compliant with ECE R13H, it maintains stable performance during rush-hour traffic, ensuring smooth braking for daily travel.
2.Long-Distance Highway Driving
Suitable for continuous high-speed driving (80-120km/h). Its heat dissipation coefficient (≥20 W/(m·K)) and max operating temp (≤600℃) (per SAE J2928) prevent brake fade during long downhill or continuous braking, keeping stopping power consistent for 400+km one-way trips.
3.Mountainous & Hilly Roads
Perfect for roads with frequent steep slopes. It cuts brake fade risk by 25% and shortens dry-road braking distance by 15% (100km/h), per ISO 11157. Even with 50+ downhill brake cycles/hour, its fatigue life (≥500,000 cycles) ensures reliable braking on winding mountain roads.
4.Harsh Weather Conditions
Effective in rainy, snowy, or coastal areas. With 480-hour salt spray resistance (ISO 9227), it resists rust from rain, snow, or salt. It boosts wet-road braking stability by 25%, avoiding skidding during wet starts/stops, suitable for regions with frequent inclement weather.
5.Commercial High-Frequency Use
Fits commercial vehicles (e.g., logistics vans) with frequent braking. Its IATF 16949-certified durability handles 100+ daily brake cycles, and the ≥500,000-cycle fatigue life reduces replacement frequency, lowering maintenance costs for commercial fleets.
Product Operate Guide
For installation, follow IATF 16949 standards: Let professional technicians mount it, then conduct a dynamic balance test (residual unbalance ≤5g·cm) to avoid vibration. For daily use, clean the disc surface every 5,000km (per ISO 4038) to remove dust; check wear monthly—replace if wear exceeds 3mm. This ensures 50,000+km service life and stable braking performance.
