TRW Automotive AfterMarket DF4367 Brake Disc

The TRW DF4367 brake disc is a high‑performance, ventilated rotor designed for front‑wheel braking systems in a wide range of vehicles. It delivers reliable stopping power, excellent heat dissipation, and long service life, making it an ideal choice for both everyday driving and demanding performance applications.

Key Features

• Ventilated Design: The rotor incorporates multiple internal channels that allow air to flow through the disc, reducing heat buildup during braking. This improves fade resistance and maintains consistent braking performance over extended periods of use.
• Durable Construction: Made from high‑strength cast iron with a reinforced core, the DF4367 offers superior structural integrity while keeping weight manageable for optimal handling dynamics.
• Precision Machining: Each disc is machined to tight tolerances, ensuring perfect fitment and alignment with brake pads. This precision reduces vibration and noise during operation.
• Corrosion Resistance: The rotor’s surface treatment protects against rust and corrosion, extending the life of the component even in harsh environmental conditions.
• Compatibility: Designed to fit a broad range of front‑wheel vehicles, including many models from Toyota, Geely, BYD, and other manufacturers. It is commonly paired with standard brake pads for optimal performance.

Technical Specifications

Performance Benefits

The ventilated construction of the DF4367 allows for rapid heat dissipation, which is critical during prolonged braking sessions such as hill climbs or spirited driving. By keeping the rotor temperature lower, brake fade—the reduction in stopping power due to overheating—is significantly minimized. This results in more predictable and reliable braking performance.

The high‑strength cast iron material provides excellent resistance to wear and impact forces, ensuring that the disc maintains its shape and integrity over thousands of miles. The reinforced core further enhances durability by preventing warping or cracking under extreme thermal loads.

Installation & Maintenance

• Removal: Use a standard socket set to loosen the wheel hub bolts, then remove the rotor from the caliper. A torque wrench is recommended for re‑installation to ensure proper clamping force.
• Inspection: Before installing a new disc, inspect the brake pads and calipers for wear or damage. Replace any components that do not meet manufacturer specifications.
• Tightening: Reinstall the rotor with a torque sequence that matches the vehicle’s service manual. This ensures even pressure distribution across the mounting surface.
• Break‑In Procedure: After installation, perform a gentle braking routine to allow the pads and disc to seat properly. Avoid hard stops for the first few hundred miles to prevent uneven wear.

Applications

The DF4367 is engineered to fit a wide array of front‑wheel vehicles. Common applications include:

• Toyota Corolla (various generations)
• Geely and BYD models that share similar wheel hub dimensions
• Other compact and midsize cars with standard front‑wheel brake systems

Because of its standardized size and mounting geometry, the disc can be swapped between compatible models with minimal adjustment.
