Upgrade your braking system with our premium-grade brake discs, engineered specifically for Great Wall Motor vehicles. We manufacture our discs using high-quality G3000 cast iron, certified to meet international ISO 9001 & ECE R90 standards. This ensures exceptional material integrity and consistent performance.
Each disc undergoes computer-controlled balancing and a specialized heat-treatment process, achieving a hardness of 187-241 HB. This significantly enhances structural durability and resistance to thermal stress, effectively preventing warping and cracking under high-temperature conditions. The result is a 30% longer service life compared to non-certified alternatives.
As a direct replacement part, our brake discs guarantee a perfect fit and seamless integration with your vehicle's OEM specifications. They are rigorously tested to deliver reliable stopping power, reduced noise, and stable friction characteristics.
Our brake discs are manufactured from high-grade G3000 cast iron, a material specifically formulated for exceptional braking performance. This alloy is certified to meet the stringent ECE R90 international standard, ensuring it matches or exceeds the quality of original equipment. Through a proprietary heat-treatment process, we achieve a uniform hardness of 187-241 HB. This significantly increases resistance to wear and thermal stress, directly translating to a 30% longer service life compared to non-certified aftermarket parts. You get a more durable product that provides reliable performance mile after mile.
Every brake disc is precision-machined using computer-numerical control (CNC) technology to ensure perfect dimensional accuracy and balance. Our strict manufacturing tolerances are within 0.05mm, guaranteeing a perfect fit and smooth operation. Furthermore, each rotor undergoes a high-speed dynamic balancing test, effectively minimizing potential brake vibration (judder). This results in a smoother pedal feel, reduced noise, and consistent, reliable contact with the brake pad for superior stopping power you can trust.
Intensive braking generates immense heat, which is the primary cause of brake fade and disc warping. Our discs feature an optimized internal vane design that maximizes airflow and heat dissipation. This advanced cooling system allows the disc to operate at temperatures up to 650°C (1202°F) without compromising structural integrity. By efficiently managing thermal load, our brakes maintain optimal performance under demanding conditions, providing the confidence you need for safe deceleration.
Trust is built on verification. Our production process includes over 20 distinct quality checkpoints, from raw material inspection to final packaging. We employ a salt spray test (exceeding 120 hours) to validate the corrosion resistance of the disc's non-friction surfaces. Additionally, our products are certified under the ISO 9001 Quality Management System. This data-driven, systematic approach to manufacturing guarantees that every brake disc you receive delivers predictable, OEM-matching performance and unwavering reliability.

Here are specific application scenarios of brake disc:
Ensure safe and reliable stopping power during everyday use. Our brake discs are engineered for consistent performance in stop-and-go city traffic, providing smooth, low-noise operation that enhances driving comfort. The high-quality materials resist the gradual wear of frequent, light braking, making them a dependable choice for the daily school run, grocery trips, and the work commute.
Engineered for drivers who require more from their braking system. If your driving involves mountainous terrain, frequent highway merging, or carrying heavy loads, our discs' advanced thermal management is crucial. They maintain stable friction coefficients and resist warping at temperatures up to 650°C, preventing brake fade and ensuring confident deceleration when it matters most.
Maximize vehicle uptime and reduce long-term operating costs for fleet operators. With a proven 30% longer service life and compliance with ECE R90 standards, our brake discs offer predictable wear and unmatched reliability. This translates to fewer unscheduled maintenance intervals, lower cost-per-mile, and consistent safety standards across your entire fleet of vehicles.
The perfect direct replacement during routine service or when upgrading worn components. As a precision-machined OE-equivalent part, it guarantees a perfect fit, eliminating installation issues. Choosing our certified brake disc is not just a repair; it's an upgrade to superior materials and engineering, enhancing the overall safety and responsiveness of the vehicle's braking system.
Product Operate Guide
To ensure the maximum performance and service life of your new brake discs, a proper break-in procedure is critical. After installation, we recommend a series of 15-20 moderate decelerations from approximately 50 mph to 30 mph, allowing for adequate cooling intervals between stops. This process gently deposits a uniform friction material layer onto the disc surface. For the first 200 miles, avoid heavy braking and prolonged hard stops. This controlled break-in period, known as "bedding-in," is essential for achieving optimal stopping power, preventing noise, and ensuring the long-term reliability of your braking system.
