TRW DF4276 Brake Disc

TRW DF4276 Brake Disc

The TRW DF4276 Brake Disc is a high‑performance braking component engineered for modern passenger vehicles, particularly those from the Volkswagen Group family—including Audi, Seat, Skoda, and VW models. Designed with precision machining and advanced material technology, this disc delivers reliable stopping power, durability, and consistent performance across a wide range of driving conditions.

Key Features

• Material Composition: High‑strength cast iron alloy optimized for heat dissipation and wear resistance.
• Diameter & Thickness: Standard 253 mm diameter with a 10 mm thickness, suitable for rear axle applications in compact to mid‑size cars.
• Heat Management: Integrated venting design enhances airflow, reducing brake fade during prolonged use.
• Surface Finish: Smooth, polished surface ensures optimal contact with brake pads and reduces noise.
• Compatibility: Certified for a wide range of models: Audi A3, Seat Altea, Seat Leon, Skoda Octavia, VW Golf V (both standard and Schrägheck), VW Golf VI, VW Golf Plus, and related variants.

Engineering Excellence

The DF4276 disc is manufactured using a precision casting process that guarantees uniform density throughout the component. This consistency is critical for maintaining balanced rotation and preventing vibration during high‑speed braking. The alloy’s composition includes controlled amounts of silicon, manganese, and carbon to achieve an optimal balance between hardness and toughness.

Its vented design incorporates a series of strategically placed channels that allow heat to escape efficiently. This feature is particularly beneficial for vehicles operating in urban environments where frequent stopping can lead to brake fade if heat buildup is not managed effectively.

Installation & Maintenance

Installing the DF4276 disc follows standard rear axle procedures. The disc attaches directly to the hub using a set screw or lock washer system, ensuring secure retention during dynamic driving conditions. For maintenance, it is recommended to inspect the disc surface for signs of glazing, scoring, or uneven wear. If such issues are detected, replace the disc promptly to maintain optimal braking performance.

Performance Benefits

• Consistent Stopping Power: The disc’s material properties provide reliable friction against brake pads, translating into predictable stopping distances.
• Reduced Noise & Vibration: Smooth surface finish and balanced construction minimize squeal and vibration during braking.
• Longevity: High wear resistance extends the service life of both the disc and accompanying brake pads, reducing long‑term maintenance costs.

Applications Across Vehicle Models

The DF4276 is specifically engineered for rear brakes in a variety of models. Below are representative vehicle families where this disc is commonly used:

• Audi A3 (8P1) – 2004‑2012
• Seat Altea, Seat Leon, Seat Toledo
• Skoda Octavia, Skoda Yeti, Skoda Caddy III Kombi
• Volkswagen Golf V (both standard and Schrägheck), Golf VI, Golf Plus
• Volkswagen Eos, New Beetle, Scirocco, Jetta, VW Cabriolet

Quality Assurance & Compliance

The TRW DF4276 disc adheres to stringent automotive industry standards. It undergoes rigorous testing for:

• Dimensional accuracy (±0.5 mm tolerance)
• Hardness and tensile strength benchmarks
• Heat resistance up to 600 °C under simulated braking loads
• Corrosion resistance in various environmental conditions

Conclusion

The TRW DF4276 Brake Disc represents a blend of advanced materials science, precise engineering, and proven performance. Whether you’re restoring a classic Audi A3 or maintaining a modern VW Golf, this disc delivers the reliability and stopping confidence that drivers expect from a trusted automotive brand.
