The brake disc, also known as the rotor, is a key component of a vehicle’s disc brake system. It is the part that the brake pads press against to create friction and slow down or stop the vehicle. Typically made from gray iron, it is designed to handle high heat and mechanical stress. Some discs are solid, while others feature vented designs with fins or vanes to improve heat dissipation, especially in heavy-duty or high-performance applications.
Our Advantages:
- Professional Manufacturing: We use advanced environmental foundry electric stoves and production lines, producing up to 5,000 tons per month. - Long Service Life & Quality Warranty: Our brake discs are designed for durability, with a warranty of 1 year or 100,000 kilometers. - Low Noise Performance: We ensure minimal noise during operation for a smoother driving experience. - Strict Testing: All products undergo rigorous dynamic balance testing to ensure stability and performance. - High-Quality Materials: Made from casting iron, following HT-250 and G3000 standards. - Vented or Solid Design: Available in both vented and solid styles to suit different vehicle requirements. - Custom Packaging: Neutral or color cartons, poly wood pallets available. - Fast Lead Time: 20 days for a 20' container. - Competitive Pricing: Accept small orders starting from 10–30 pieces. - Custom Production: Capable of handling complex manufacturing tasks, including size adjustments, material formula changes, surface treatments like DACROMET, zinc plating, black coloring, and more. - Global Reach: Products are exported worldwide, including countries such as Czech Republic, Lithuania, Georgia, Australia, Middle East, and Africa. - Professional R&D Team: We have an experienced team to support product development and innovation. - Compliance & Certifications: ISO 9002 and TS16949 certified, with short-term export credit insurance available. - Experience in Export: With many years of export experience, we are familiar with international certifications and customs regulations. - Support for Custom Designs: We can produce based on customer drawings or samples for new parts. Whether you need car or truck brake discs or drums, we offer a wide range of options tailored to your needs. We welcome any inquiries and look forward to building a long-term partnership with you.
