TRW Automotive AfterMarket DF4864S Brake Disc

TRW Automotive AfterMarket DF4864S Brake Disc

The TRW DF4864S brake disc is a high‑performance, ventilated rotor engineered for the rear axle of Mercedes‑Benz vehicles. Designed to replace OEM components, it delivers superior heat dissipation and consistent braking under demanding driving conditions.

Key Design Features

• Ventilated Construction: The disc incorporates a series of precisely machined channels that allow air to flow through the rotor. This design reduces heat buildup, maintaining optimal friction levels during prolonged use.
• High‑Carbon Alloy: Manufactured from a proprietary high‑carbon steel blend, the DF4864S offers enhanced strength and resistance to wear. The alloy composition also improves thermal conductivity, ensuring rapid cooling after each braking event.
• 300 mm Diameter & 22 mm Thickness: These dimensions match the original specifications for a wide range of Mercedes‑Benz models, providing a seamless fit without requiring additional modifications.
• Precision Machining: Each rotor is ground to an exact tolerance, guaranteeing uniform contact with brake pads and minimizing vibration during operation.

Compatibility Overview

The DF4864S is engineered for the following Mercedes‑Benz platforms:

• C‑Class (W204) – 2007‑2014 models, including C207 and A207 variants.
• E‑Class Coupe (C207)
• T‑Model (S204)
• C‑Class Sedan (C204) – 2007‑2014 range.

For each model, the rotor is available in a single‑piece configuration or as part of a paired set for rear axle installation. The product’s specifications align with the OEM “DF4864S” designation, ensuring compatibility across all listed variants.

Performance Benefits

• Consistent Braking: The ventilated design keeps rotor temperatures lower, preventing brake fade during high‑speed or heavy‑load scenarios.
• Extended Life: High‑carbon alloy reduces wear on both the disc and accompanying pads, extending service intervals.
• Improved Safety: Reliable heat management translates to predictable stopping distances, enhancing overall vehicle safety.

Installation Highlights

Installing the DF4864S is straightforward for technicians familiar with rear brake systems. Key steps include:

1. Remove Existing Rotor: Detach the current disc and clean the hub surface to ensure proper seating.
2. Check Hub Integrity: Inspect for scoring or damage; replace if necessary to avoid future issues.
3. Mount the New Disc: Align with the mounting flange, secure with the supplied bolts, and torque to manufacturer specifications.
4. Reinstall Pads & Calipers: Fit new brake pads (if required) and reattach calipers, ensuring proper clearance for the ventilated channels.
5. Brake Fluid Check: Verify fluid levels and perform a bleed to eliminate air pockets.

Maintenance Tips

• Regularly inspect pad wear; replace pads when thickness falls below manufacturer guidelines.
• Keep the rotor surface free of debris. Use a brake cleaner before reassembly if necessary.
• Monitor rotor temperature during extended driving sessions, especially in hot climates or heavy traffic.
