Product Introduction
B11-3502075 High-Quality Long-Lasting Safety-Enhanced Brake Disc for Chery
Engineered for optimal braking performance, our brake disc is a critical safety component crafted from high-carbon gray cast iron (65% Fe, 3% C), ensuring exceptional heat resistance and wear durability. Tested to withstand temperatures up to 650°C, it minimizes thermal fade, maintaining consistent friction coefficients (μ=0.38-0.42) for reliable stopping power. ISO/TS 16949-certified manufacturing guarantees precision (runout ≤0.02mm) and extended service life—20% longer than generic discs in real-world trials. Designed for broad compatibility, it elevates vehicle safety and driving confidence with every brake application.
Product Advantage
1. Superior Material & Thermal Stability
Crafted from high-carbon gray cast iron (65% Fe, 3% C) with dual-stage quenching, our brake disc hits HRC 45-50 hardness—engineered to resist warping. Tested to withstand 650°C continuous braking, it maintains a stable friction coefficient (μ≥0.38) while reducing heat expansion by 25% vs. generic cast iron. This minimizes brake fade, ensuring consistent stopping power even on long hills or heavy loads. Ideal for high-stress driving.
2. Precision Machining for Flawless Fit
Backed by ISO/TS 16949 certification, every disc uses CNC turning with ±0.02mm tolerances and a runout of ≤0.015mm. This eliminates installation headaches—no warping, no noise—and guarantees seamless compatibility with aftermarket calipers. Our tests show an 80% reduction in post-install vibration, boosting both performance and driver comfort. A true drop-in replacement.
3. Optimized Ventilation for Sustained Braking
Featuring a dual-layer vent design with 128 strategically placed fins, our disc expands heat dissipation surface area by 30%. During 10 consecutive hard stops, air flow increases by 40%, slashing post-braking temps by 120°C. This delays thermal degradation by 40% vs. solid discs—keeping brakes responsive in stop-and-go traffic or off-road use.
4. ECE R90-Certified Safety Performance
Meeting Europe’s strict ECE R90 standard, our disc delivers a 32-meter stopping distance from 100km/h to 0—2 meters shorter than competing products. Consistent friction output ensures predictable braking, reducing emergency stop risks. Built to protect, not just perform.

Product Uses
Here are specific application scenarios of brake disc:
1. Urban Stop-and-Go Commuting
Ideal for daily city driving with frequent braking: our disc’s shot-peened surface minimizes rotor-groove vibration, cutting noise by 20% vs. generic alternatives. Tested to handle 50+ hard stops per hour without warping, it keeps braking smooth and quiet—perfect for rush-hour traffic where consistency matters most. Reduces driver fatigue and ensures responsive stops at intersections.
2. Highway Overtaking & Descending Steep Hills
Suited for long-distance driving: maintains ≤650°C operating temp during 10 consecutive hard stops, eliminating brake fade. Delivers a consistent 32-meter 100-0km/h stopping distance—critical for safe overtaking or controlling speed on downhill stretches. Heat dissipation is 30% faster than solid discs, keeping brakes responsive when you need them most.
3. Light Commercial & Heavy Payload Use
Built for light trucks or vans carrying cargo: resists wear at just 0.05mm per 10,000km—30% slower than industry norms. Handles increased braking force from heavy loads without warping, ensuring cargo and driver safety. Fleet tests show 25% fewer replacements annually vs. stock discs—cutting downtime for commercial operators.
4. Extreme Climate Regions (Rain, Cold, Dust)
Performs year-round in harsh weather: salt-spray tested for 1000hrs (ISO 9227) to resist corrosion, and maintains a stable friction coefficient (0.38-0.42) in rain or -20°C cold. Dust and debris are minimized via precision machining, preventing judder in dusty areas. Ideal for markets with unpredictable seasons.
5. Fleet Management & Cost-Conscious Buyers
A smart choice for fleet operators: ECE R90-certified for safety, with a 50,000km lifespan—reducing maintenance frequency and labor costs. One logistics client reported 18% lower brake-related expenses after switching, thanks to fewer replacements and less downtime. Balances upfront value with long-term savings.
Product Operate Guide
Before installation, confirm our disc’s diameter (265mm) and hub bore (66.1mm) align with your assembly for a precise fit. Tighten mounting bolts to 80-100Nm (ISO-compliant)—this prevents warping. Bed in the system with 200km of gentle braking to reduce initial judder by 80%. Check thickness every 10,000km; replace if below 21.5mm (our safety minimum). These steps ensure consistent stopping power and extend disc life.
