TRW Automotive AfterMarket DF2767 Brake Disc – An In‑Depth Overview

The TRW Automotive AfterMarket DF2767 Brake Disc is a high‑performance, ventilated rear brake disc designed specifically for the BMW 3‑Series (E36, E46) and related models. It is engineered to deliver superior stopping power, heat dissipation, and durability under a wide range of driving conditions.

Key Design Features

• Diameter and Thickness: 276 mm outer diameter with a 19 mm thickness, providing an optimal balance between strength and weight.
• Ventilation: Multiple radial cooling vents reduce heat buildup, ensuring consistent braking performance during extended use.
• Drilling Pattern: 120 mm central bore with a precise drilling pattern that matches the original BMW mounting system.
• Material Composition: High‑grade cast iron alloy with a thermal expansion coefficient tailored to match the brake pad material, minimizing wear.
• Surface Finish: Smooth, factory‑finished surface that promotes even pad contact and reduces noise.

Compatibility Matrix

The DF2767 is engineered to fit a broad range of BMW 3‑Series variants, including:

Performance Benefits

• Enhanced Heat Dissipation: The ventilated design allows air to flow through the disc, reducing thermal stress and preventing brake fade during aggressive driving.
• Consistent Stopping Power: The disc’s geometry ensures uniform pad wear, maintaining braking efficiency over the life of the component.
• Reduced Weight: Compared to stock cast iron discs, the DF2767 offers a slight weight reduction, contributing to overall vehicle performance.
• Longevity: Built with a high‑strength alloy, the disc resists cracking and warping even under extreme temperatures.

Installation Guidelines

1. Remove Existing Disc: Carefully detach the current brake disc, noting any retained hardware such as retaining screws or anti‑rotor shims.
2. Clean the Hub: Use a brake cleaner to remove grease, dust, and old brake pad residue from the hub surface.
3. Align the Disc: Position the DF2767 disc onto the hub, ensuring that the central bore aligns perfectly with the wheel spindle.
4. Secure Fastening: Tighten the retaining bolts to the manufacturer’s specified torque (typically 80–100 Nm) using a calibrated torque wrench.
5. Reinstall Brake Pads: Fit the new brake pads, ensuring proper alignment with the disc surface.
6. Bleed the Brake System: Perform a brake bleed to eliminate air pockets, guaranteeing optimal hydraulic pressure.
7. Test Drive: Conduct a low‑speed test drive to confirm that the brakes engage smoothly and without vibration.

Maintenance Tips

• Regular Inspection: Check for signs of wear, such as uneven pad contact or disc glazing, every 10,000 km.
• Brake Fluid Check: Replace brake fluid every 2 years to maintain hydraulic integrity.
• Pad Compatibility: Pair the disc with high‑quality brake pads that match the disc’s thermal profile for optimal performance.
• Avoid Over‑Cooling: Do not use aftermarket cooling devices that may alter the disc’s heat balance.
