TRW Automotive AfterMarket DF4948 Brake Disc

The TRW DF4948 is a high‑performance brake disc designed specifically for the Mercedes‑Benz C‑Class series (W204, S204, C204). It delivers reliable stopping power, durability, and consistent performance under demanding driving conditions.

Key Features & Benefits

• Precision Engineering: Manufactured with advanced CNC machining to ensure exact dimensional tolerances for optimal fitment and balance.
• Robust Construction: Made from a high‑strength steel alloy that resists warping, cracking, and excessive wear.
• Optimized Heat Dissipation: Features a 9 mm thick rim with a 100 mm diameter hole pattern to enhance airflow and reduce heat buildup during heavy braking.
• Long‑Lasting Performance: Designed to maintain consistent braking efficiency over extended periods, even under high‑temperature conditions.
• Easy Installation: Comes with a standard mounting flange that matches the original equipment specifications for straightforward replacement.

Technical Specifications

Installation Guide

1. Preparation: Remove the existing brake disc using a suitable impact wrench. Clean the hub surface with isopropyl alcohol to eliminate grease or debris.
2. Mounting: Align the new DF4948 disc with the mounting flange and secure it with the supplied bolts. Torque the bolts to the manufacturer’s specified value (typically 80–100 Nm).
3. Brake Pad Installation: Install compatible brake pads that match the disc’s dimensions. Ensure proper pad alignment to avoid uneven wear.
4. Bleeding & Testing: Bleed the braking system to remove air bubbles, then test the vehicle at low speeds to confirm correct operation before full deployment.

Performance Highlights

• Consistent Braking: The disc’s uniform thickness and precise machining reduce vibration and noise during high‑speed braking.
• Heat Management: The 100 mm hole pattern allows rapid heat dissipation, preventing brake fade in spirited driving or heavy traffic scenarios.
• Durability: Engineered to withstand repeated thermal cycling without compromising structural integrity.

Why Choose the TRW DF4948?

The TRW DF4948 is engineered for drivers who demand reliable stopping power and long‑term durability. Its compatibility with a wide range of Mercedes‑Benz C‑Class models makes it an ideal choice for both routine maintenance and performance upgrades.

Maintenance Tips

• Inspect the disc surface regularly for signs of glazing or uneven wear.
• Replace brake pads when pad thickness falls below 2 mm to maintain optimal contact with the disc.
• Avoid driving on wet, icy roads at high speeds to reduce the risk of hydroplaning and excessive heat buildup.

Conclusion

The TRW Automotive AfterMarket DF4948 Brake Disc offers a blend of precision engineering, robust construction, and proven performance. It is an excellent choice for anyone looking to maintain or enhance the braking capabilities of their Mercedes‑Benz C‑Class vehicle.
