TRW Automotive AfterMarket DF4247 Brake Disc – A Comprehensive Overview

The TRW Automotive AfterMarket DF4247 Brake Disc is a high‑performance, ventilated carbon‑enhanced rotor designed specifically for rear applications on a range of Opel and Vauxhall models, including the Omega B, Caravan, and other V94‑series vehicles. This article delves into every aspect of the DF4247, from its engineering specifications to real‑world performance benefits.

Engineering Excellence

The DF4247 is engineered with a 286 mm diameter and 20 mm thickness, providing an optimal balance between stopping power and weight. Its ventilated design incorporates multiple internal channels that allow heat to dissipate efficiently, reducing the risk of brake fade during prolonged use.

Key material features include:

• High‑carbon steel alloy – Enhances thermal conductivity and improves resistance to wear.
• Surface finish – A finely machined, matte surface ensures consistent pad contact and reduces noise.
• Pre‑tapped holes – Facilitate quick and secure mounting, compatible with standard rear brake caliper assemblies.

Compatibility and Fitment

The DF4247 is specifically tailored for the following vehicle models:

• Opel Omega B (V94) – Sedan and Caravan variants.
• Vauxhall Omega B (V94) – Including the 1994‑1999 model range.
• Other V94 series vehicles – such as the F35, M35, P35, F69, and M69.

Each rotor is available in a single‑piece configuration, ensuring that the entire assembly can be replaced with minimal labor. The 286 mm diameter matches the OEM specifications for these models, guaranteeing a seamless fit.

Performance Benefits

When paired with compatible brake pads, the DF4247 delivers:

• Consistent stopping power – Even under high‑temperature conditions.
• Reduced brake fade – Thanks to the ventilated design and high‑carbon material.
• Lower unsprung weight – Contributing to improved handling and ride quality.
• Longer rotor life – The carbon‑enhanced alloy resists corrosion and wear.

Installation Guide

Installing the DF4247 is straightforward for experienced mechanics:

1. Remove the existing rotor – Use a torque wrench to loosen and remove the caliper bolts.
2. Clean the hub surface – Ensure no debris or old brake dust remains.
3. Position the new rotor – Align it with the mounting points and secure with the supplied bolts.
4. Reinstall the caliper – Tighten bolts to the manufacturer’s torque specification.
5. Bleed the brake system – Remove any air pockets for optimal performance.

Maintenance Tips

To keep the DF4247 performing at its best, follow these simple maintenance steps:

• Inspect the rotor surface for scoring or glazing every 10,000 km.
• Replace brake pads when pad wear indicators are audible or when pad thickness falls below 3 mm.
• Check rotor alignment periodically to prevent uneven wear.
• Keep the brake system free of moisture by storing the vehicle in a dry environment.
