TRW Automotive AfterMarket DF4087S Brake Disc

The TRW DF4087S Brake Disc is a high‑performance, OEM‑grade component engineered for rear braking systems on a wide range of Mercedes-Benz, Audi, and Volkswagen vehicles. Designed with precision machining and advanced material composition, this disc delivers consistent stopping power, durability, and reliability under demanding driving conditions.

Key Design Features

• Diameter: 258 mm – a standard size that matches the rear wheel hubs of many commercial and passenger models.
• Thickness: 12 mm – provides a robust structural profile while maintaining optimal heat dissipation.
• Hole Diameter: 130 mm – accommodates the central hub and rotor mounting hardware, ensuring secure attachment.
• Material Composition: High‑strength steel alloy with a proprietary surface treatment that resists corrosion and wear.
• Heat Management: The disc’s geometry promotes efficient heat transfer away from the braking interface, reducing fade during prolonged use.

Compatibility Overview

The DF4087S is engineered to fit a broad spectrum of rear axle configurations across multiple vehicle families. Its dimensions and mounting specifications align with OEM requirements for:

• Mercedes-Benz G‑Class (W463) – models from the early 1990s through the late 2000s.
• Mercedes-Benz Sprinter series – including 3‑t, 4‑t vans and platform chassis variants.
• Audi, Volkswagen, and other German‑manufactured vehicles that share similar rear suspension layouts.

Because the disc is a direct replacement for original equipment, it integrates seamlessly with existing brake pads, calipers, and hydraulic systems without requiring additional modifications.

Performance Characteristics

• Consistent Braking: The uniform thickness and precise machining ensure even pad contact across the entire rotor surface.
• Reduced Noise & Vibration: Advanced surface finishing minimizes squeal and chatter during operation.
• Long‑Term Durability: Corrosion‑resistant coating extends service life, especially in harsh climates or high‑humidity environments.
• Heat Dissipation: Optimized cross‑sectional area facilitates rapid heat removal, maintaining braking performance during heavy use.

Installation Guidance

Installing the DF4087S is straightforward for technicians familiar with rear brake assemblies. Key steps include:

1. Remove the existing rotor and clean the hub surface to eliminate debris.
2. Align the new disc’s central hole with the mounting bolts, ensuring a snug fit.
3. Torque the mounting hardware to the manufacturer’s specifications to guarantee secure attachment.
4. Reinstall brake pads and calipers, then perform a brake fluid bleed to eliminate air from the system.

After installation, a brief test drive is recommended to confirm proper operation and to allow the disc to reach its optimal operating temperature.

Maintenance Tips

• Inspect the rotor surface regularly for signs of glazing or uneven wear.
• Replace brake pads when pad thickness falls below the manufacturer’s minimum threshold, as this can affect disc performance.
• Avoid driving on wet or icy roads at high speeds to reduce heat buildup and potential thermal stress.
